 Abstract

- Cranial fasciitis is a rare fibroblastic tumor which shows a predilection for the scalp of young children. We present a child with a rapidly growing mass and lytic skull lesion which on pathologic evaluation was diagnosed as cranial fasciitis. Histologically this lesion was identical to nodular fasciitis which was typically found in the trunk and extremities of adults. Cranial fasciitis is unique in that it may present as a lytic lesion in the skull, but this disease entity is not widely known to pathologists and radiologists, and should be included in the differential diagnosis of fibroblastic lesion occurring in the cranium of young children.

- We evaluated the frequency of genetic alteration of chromosome 3p in lung cancer, and analyzed the patterns of genetic alterations between two distinct histologic types, squamous cell carcinomas (SCC) and adenocarcinomas (AC).
PCR-LOH analysis for 40 Korean non-small cell lung cancer including 20 SCC and 20 AC was performed using microsatellite markers, D3S1300, D3S1029 and D3S1038. These markers represented the loci of FHIT gene (3p14), mismatch repair gene hMLH1 (3p21) and VHL gene (3p25), respectively.
For SCC, the frequency of LOH at D3S1300, D3S1029 and D3S1038 was 78.6%, 61.5% and 64.3%, and for AC, was 62.5%, 62.5% and 46.7%, and for total 40 cases of SCC and AC, was 70.0%, 62.1% and 55.2%, respectively. Among 27 cases showing heterozygosity at three examined loci, 7 cases (25.9%) revealed LOH at only one locus and 16 cases (59.3%) revealed LOH at two or three loci. The differences of incidence of LOH and the patterns of genetic alterations at chromosome 3p between two distinct histologic types of lung cancer were not significant. The genetic deletion of relatively broad area, including more than two loci, was more frequent than that of small area, including only one locus.

Abstract
- Recently, p53, c-erbB-2 and nm23 proteins have been studied in breast cancer. The expression of p53 protein indicates the mutation of p53 gene known as a tumor supressor gene, and c-erbB-2 gene amplification has been considered an indicator of poor prognosis and nm23 a metastsis suppressor gene. In order to elucidate the roles and relations of these proteins in the develpoment, progression and metastasis in breast cancer, we studied 89 cases of invasive breast cancer and 32 cases of lymph node metastasis for the expression of p53, c-erbB-2 and nm23 proteins using an immunohistochemical method. The results were as follows: 1) The expression rates of p53, c-erbB-2, and nm23 proteins in breast cancer were 40.4%, 34.8% and 55.1%, respectively. Co-expression of p53 protein and c-erbB-2 protein was found in 20.2% of cases, showing the highest incidence in poorly differentiated type (40%). 2) p53 protein expression was increased in poorly differentiated type but was not statistically significant.
On the other hand, the expression of nm23 protein was decreased in poorly differentiated type, which was statistically significant (p<0.05). 3) The correlation of p53 protein expression with c-erbB-2 protein expression was statistically significant (p<0.05) but that with nm23 protein was not. 4) In the cases with lymph node metastasis, discordant expression of p53, c-erbB-2 and nm23 proteins between primary tumor and the lymph node metastatic tumor was found in 9.4%, 3.1% and 18.8% of cases, respectively.
The above results suggest that overexpression of p53 and c-erbB-2 proteins and downregulation of nm23 protein are associated with the tumor progression in the breast cancer.

Abstract
- Prolymphocytic leukemia is a chronic lymphoproliferative disorder, characterized by prominent splenomegaly, prolymphocytes accounting for more than 55% of circulating lymphocytes, no significant peripheral lymphadenopathy and short term survival with terminal fatal multi-organ failure.
We report a case of B-cell prolymphocytic leukemia in a 57-year-old woman who presented with easy bruising and arthritis for 1 year and low abdominal pain for 2 months.
Physical examination revealed gingival hypertrophy and mild splenomegaly. On peripheral blood smears the leukocytes were markedly increased in number due to leukemic cells that count about 62% of leukocytes. The bone marrow aspiration smear and biopsy revealed diffuse infiltration of medium to large prolymphocytes having moderate amount of basophilic cytoplasm, round to oval nuclei with coarse chromatin, and prominent nucleoli. Abdominal pain aggravated despite chemotherapy, and pelvic computed tomography (CT) revealed a huge lobular pelvic mass which had increased in size on the follow-up CT. Total hysterectomy with bilateral adnexectomy was performed. Microscopic findings included massive infiltration of prolymphocytic cells in the uterus, upper vaginal wall, bilateral ovaries, and bilateral mesosalpinges. On immunohistochemistry, the leukemic cells showed B cell gamma light chain phenotype.

Abstract

- Sometimes a pilomatrixoma on upper neck can be misdiagnosed as primary salivary gland tumor, skin adnexal tumor or metastatic carcinoma. On fine needle aspiration cytology(FNAC), characteristic features are ghost cells, basaloid cells, and calcium deposits, among which presence of ghost cells seems to be the key to recognize it. Here we present a cytologically misdiagnosed case of pilomatrixoma.
A 32-year-old man presented a subcutaneous mass on the right posterior neck. It has grown slowly for 1 year, and was nontender, well circumscribed, hard, and movable mass. An initial FNAC yielded only monomorphic population of highly mitotic basaloid cells, without anucleated ghost cells, chronic inflammatory cells or foreign-body giant cells, suggestive of a poorly differentiated carcinoma. However, that was inconsistent with patient's clinical findings. For further correct diagnosis, FNAC was repeated, which yielded the basaloid cells and foreign-body giant cells. The diagnosis of pilomatrixoma could be made and the mass was excised. This case demonstrates that the pilomatrixoma should be considered in the differential diagnosis of subcutaneous aspirates containing not ghost cells but a dominant population of basaloid cells.

Abstract
- Serratia marcescens is the most important member of the genus Serratia and causes opportunistic infections, particularly pneumonia and septicemia in patients with malignancy, renal failure (acute and chronic), and diabetes mellitus. The most common portals of entry are known to be, in descending order, lung, genitourinary tract, intravenous line, gastrointestinal tract, and skin. S. marcescens rarely causes skin infection because it does not normally colonize human skin. Only six cases of S. marcescens cellulitis were reported. Five of them were immunocompromised patients. We have experienced a case of skin abscess caused by S.
marcescens, which was found in a 59-year-old woman. She was undergoing prior antibiotic treatment after insulinoma surgery. S. marcescens was isolated from the skin abscess as a sole organism. She was treated with appropriate antibiotics that exhibited sensitivities for the organism and cured without any complication. The authors report a case of S. marcescens infection on the skin of a 59-year-old woman and review the literature concerning this organism as a causative agent.

Abstract
- Heterotopic brain tissue is a developmental anomaly of neurogenic origin with no malignant potential, and is usually present around the nose of children and infants. So it has been called nasal glioma. But, even more rarely, heterotopic glial tissue may be found in various sites other than nasal cavity, such as the ethmoidal sinus, palate, tonsillar area, pharynx, ear, subcutaneous tissue, lung, and female genital tract. We experienced a more unusual case of a polypoid heterotopic brain tissue in the soft palate in a 3-year-old boy. The mass was microscopically reminiscent of "gliosis" of the central nervous system and interestingly contained choroid plexus focally. The glial nature of the lesion was confirmed by glial fibrillary acidic protein immunostain.

Abstract
- Paneth cell-rich carcinoma is essentially an adenocarcinoma with a predominance of Paneth cells. A 60-year-old male patient was admitted with a history of abdominal distension for several months. Endoscopic examination revealed a large ulceroinfiltrative tumor involving most of the areas of the stomach. The biopsy of the lesion confirmed poorly differentiated adenocarcinoma and total gastrectomy was followed. The submitted total stomach contained a diffuse infiltrative Borrmann type IV mass with ulceration, 8.0 3.5 cm, at the body along the lesser curvature. Microscopically, it was composed of Paneth cell differentiated cancer cells and poorly differentiated tubular adenocarcinoma cells. The Paneth cell differentiation was characterized by cytoplasmic coarse eosinophilic granules, which were PAS-positive and positive reaction for lysozyme. Electron microscopic examination showed numerous, spherical, electron-dense, homogeneous granules corresponding to those in Paneth cells as well as mucin granules in the signet-ring cells, and various intermediate forms in some cancer cells, which might be immature in the Paneth cell lineage.

Abstract

- The bone marrow biopsy is an integral part of the staging process in patients with malignant lymphomas. Bone marrow(BM) involvement indicates stage IV disease, but there are always a lot of cases in which clear separation is not possible when based on morphology alone. Additional difficulties are caused by morphologic discordance between the BM and the primary lymphoma. Immunohistochemical stain, mRNA in situ hybridization (ISH) for light chain restriction and polymerase chain reaction (PCR) for IgH CDR3 and TCRgamma were performed to find a minimal lesion and the clonality in formalin fixed paraffin embedded tissues of 39 primary lymphomas and corresponding BM biopsy specimens. As a result, nine morphologically negative bone marrows of 18 lymphomas were positive by PCR (Group I). Among the 6 lymphoma cases with morphologically suspicious BM involvement (Group II), one was confirmed to be positive for marrow involvement by both mRNA ISH and PCR and the other four by PCR alone. The positive bone marrows of Group I and II revealed gene rearrangement at the same site as the primary lesion, suggesting the same clonality. Thirteen of 15 lymphomas with morphologically positive BM (Group III) had the same clonality in the primary lymphomas and the BM lesion. Three cases among the Group III with morphologic discordance also revealed the same clonality by PCR. This study shows that a combination of mRNA ISH and PCR in addition to an immunohistochemical stain improves the diagnostic sensitivity in the detection of BM involvement and identification of clonality. Among the three different methods used, PCR is the most sensitive in detecting a minimal lesion.

Abstract
PDF
- Considerable controversy exists concerning the value of histomorphological data in the assessment of the malignant potential of prostate carcinomas. Mutations in the p53 gene resulting in the accumulation of altered p53 proteins with prolonged half-life have been found in a large variety of human malignancies. E-Cadherin is a specific epithelial cell-to- cell adhesion molecule which has previously been found to be expressed in well-differentiated non-invasive carcinoma cell lines, but it is lost in many poorly differentiated invasive cell lines. We performed immunohistochemical staining of p53 and E-cadherin in formalin fixed paraffin embedded tissues of 58 primary prostatic carcinomas. The expression rates of p53 and E-cadherin proteins in prostate carcinoma were positive in 15.5% and 44.8% of the cases, respectively. Histologically high-grade prostate carcinoma shows an increased expression of the p53 protein and a decreased one of the E-cadherin protein (P<0.05). The expression rates of the E-cadherin protein in prostate carcinoma decreased significantly according to the higher clinical stages and PSA levels (P<0.05). There was no accordance between the expression rate of p53 and E-cadherin. There were no significant correlation between each of the clinical stages and the expression rate of p53 protein or the PSA levels and the expression rates of p53 protein (P<0.05). Based on the present study, the expression of p53 and down regulation of E-cadherin are correlated with tumor progression and metastasis, and may be a useful prognostic factor in prostate carcinoma.

Abstract

- Infection by pseudallescheria boydii is an occasional cause of mycetoma, corneal ulcers, endophthalitis, sinusitis, pneumonia, endocarditis, meningitis, arthritis, and osteomyelitis. But, it also causes serious disseminated or localized infection in immunocompromised patients. We report a case of pulmonary pseudallescheriasis developed in a 32-year-old man who has been a sofa manufacturer for several years. He presented with a cystic mass in the lung, 5cm in the largest dimension. Dark green necrotic material was evacuated from the cavity. Microscopically, the cystic wall and adjacent lung parenchyme were infiltrated by histiocytes rather than eosinophils and there was little fibrosis in the wall. The P. boydii was isolated from the cystic contents, which revealed white floccose colonies in Sabouraud dextrose agar and revealed single or multiple-celled oval conidia being produced on short hyalinated hyphae and on the elongated annellides in the slide culture. The differential findings with aspergillosis are discussed.

Abstract

- Expression of the nm23 and E-cadherin proteins has been studied in a number of tumors. Reduced expression of the nm23 and E-cadherin proteins seems to be associated with metastasis or disease progression in some tumors, including breast carcinoma. To assess the role of nm23 and E-cadherin in tumor differentiation and metastasis of breast carcinoma, immunohistochemical staining for the nm23 and E-cadherin proteins was performed in paraffin embedded tumor samples from 86 breast carcinomas. The results were as follows: 1) Expression of the nm23 protein in breast carcinoma was strong positive in 32 cases (37.2%), weak positive in 26 cases (30.2%), and negative in 28 cases (32.6%) of the cases. Expression of the nm23 protein in breast carcinoma decreased according to histological grade and lymph node metastasis, but was not statistically significant. 2) Expression of the E-cadherin protein in breast carcinoma was strong positive in 50 cases (58.1%), weak positive in 24 cases (27.9%), and negative in 12 cases (14%) of the cases.
Expression of the E-cadherin protein in breast carcinoma decreased according to histological grade and lymph node metastasis, but was not statistically significant. 3) There was a statistically significant correlation between the expression of the nm23 protein and the E-cadherin protein in breast carcinoma (p<0.05). These results suggest that the expression of the nm23 and E-cadherin proteins is related to tumor differentiation, and may also be an useful prognostic factor in breast carcinoma.

Abstract

- Adenoma malignum is an extremely well-differentiated variant of cervical adeno carcinoma in which the cells composing the tumor lack the typical cytological features of malignancy. The prognosis of this rare tumor is poor in spite of high degree of differentiation. The cytologic characteristics are extremely bland, so frequently make a confusion of adenoma malignum with endocervical glandular hyperplasia.
We report a case of adenoma malignum in a 36-year-old woman who complained of mucoid vaginal discharge and vaginal bleeding.
The cervicovaginal smear showed endocervical cells exhibiting a spectrum of atypical changes. The cells were arranged in multilayered strips and monolayered sheets. Individual cells ranged from cuboidal to columnar; typically the columnar cells had abundant lacy or vacuolated cytoplasm. The smear showed the majority of only atypical cells and small numbers of frankly malignant cells.

- Cytologic features of a poorly differentiated "insular" carcinoma of the thyroid are presented. In fine needle aspiration cytology, the aspirates were highly cellular and tumor cells were arranged in loose clusters or singly dispersed on focally necrotic background. Occasional microfollicles were evident. The tumor cells had poorly defined, scanty cytoplasm and most of the nuclei were fairly uniform with coarse chromatin pattern. A few large pleomorphic cells were also noted. The cytologic findings of the present case were correlated well with the histologic findings, which showed typical insular pattern and the presence of uniform cells with occasional pleomorphism.

- We present a case of mucous gland adenoma arising from the main bronchus of the lower lobe of the left lung in terms of clinicopathologic, immunohistochemical, and ultrastructural aspects as well as review of related literatures. The patient, a 31-year-old female, was admitted to Catholic University Medical College Hospital with complaints of coughing and purulent sputum for about seven years. The chest CT showed a severely calcified tumor in the left lower lobe of the lung. Grossly, the calcified tumor arising from the main bronchus protruded into the lumen and showed bronchiectasis of the lower lobe and atelectasis of the upper lobe of the lung. The tumor was pale brown-gray and sharply circumscribed and showed some small cystic spaces filled with mucoid material. Microscopically, most of the tumor showed dystrophic calcification. The growth pattern of the tumor is composed of cysts, tubules, and glands lined by cytologically bland columnar, cuboidal, or flattened mucus secreting cells. Electron micrograph of tumor cells showed some round or oval mucous granules measuring 0.5-1.8 micrometer.

- To elucidate the role of p53 and nm23 in the development, progression, and metastasis of non-small cell lung cancer, we studied 91 paraffin sections of the primary non-small-cell lung cancers and the 34 paraffin sections of their metastatic lymph nodes using the immunohistochemical method. The results are as follows: 1) The incidence of p53 protein expression was positively correlated with the staging of lung cancers (p<0.025). 2) The incidence of p53 protein expression was higher in the lung cancers with lymph node metastasis than in those without lymph node metastasis (p=0.009). 3) The incidence of nm23 protein expression was lower in the adenocacinomas than in the squamous cell carcinomas (p=0.032). 4) The incidence of nm23 protein expression was lower in the lung cancers with lymph node metastasis than in those without lymph node metastasis (p=0.026). The expression of nm23 protein between the primary lung cancers and corresponding metastatic lymph nodes showed positive correlation (Kendall's Tau-b correlation coefficient=0.47140, p=0.0068). 5) The expression of p53 was not correlated with the expression of nm23 protein (Kendall's Tau-b correlation coefficient=0.11387, p=0.2800). The above results suggest that an overexpression of p53 protein and a downregulation of nm23 protein are associated with tumor progression and metastasis in non-small-cell lung cancer.

Abstract
PDF
- Sertoli-Leydig cell tumors of the ovary are rare, accounting for no more than 0.5% of all ovarian neoplasms. These tumors occur predominantly in women 10 to 30 years of age.
Heterologous elements are found in over 20% of the moderately and poorly differentiated Sertoli- Leydig cell tumors. The most common element is gastrointestinal mucin-secreting epithelium, found in approximately 20% of all cases. Approximately 4% of Sertoli-Leydig cell tumors contain immature skeletal muscle and/or cartilaginous elements. The origin of these neoplasms is regarded as neometaplasia of the mesodermal neoplastic element. While the degree of differentiation of Sertoli-Leydig cell tumors is probably of greater importance in determining prognosis than the presence of heterologous components, recent evidence does point to an unfavorable effect on clinical outcome when heterologous mesenchymal components such as cartilage and striated muscle are present. We experienced two cases of ovarian heterologous Sertoli-Leydig cell tumors with gastrointestinal type epithelium and striated skeletal muscle in 20 and 21 year-old females, respectively. One case involved a patient who had complained of amenorrhea for 3 years while the other case involved a patient who had complained of left lower abdominal tenderness and amenorrhea for one and one half years. It was determined by ultrasonography of the pelvis that the two patients suffered from right and left ovarian masses. Both patients underwent adnexectomy. These tumors were large with partly solid and partly cystic areas. Based on light microscopic examination one case was classified as an intermediate Sertoli-Leydig cell tumor with heterologous gastrointestinal type epithelium, while the other case was classified as a poorly differentiated Sertoli-Leydig cell tumor with heterologous striated skeletal muscle.

Abstract
PDF
- The principal significance of the urothelial changes caused by polyomavirus activation is in an erroneous diagnosis of urothelial cancer; however, the clue to their benign nature is the smooth structureless nuclear configuration and the relative paucity of affected cells. Though virologic studies and electron microscopy are usually needed to firmly establish the diagnosis, cytology is the most readily available and rapid means of establishing a presumptive diagnosis of human polyomavirus infection. A urine specimen of a 24-year-old man with hemorrhagic cystitis beginning two months after bone marrow transplantation for acute myeloblastic leukemia(M2) was submitted for cytologic evaluation. Cytologic findings revealed a few inclusion-bearing epithelial cells intermingled with erythrocytes, neutrophils, lymphocytes, and macrophages.
Most of the inclusion-bearing -cells had large, round to ovoid nuclei almost completely filed with homogeneous dark, basophilic inclusion. The chromatin was clumped along the periphery and the cytoplasm was mostly degenerated. The other cells exhibited irregular inclusions attached to the nuclear membrane surrounded by an indistinct halo. These findings were consistent with polyomavirus infection.

Abstract

- Gaucher's disease is an autosomal recessive disorder resulting fror i mutation at the glucocerebrosidase locus on chromosome 1q21. As a result, glucocerebroside accumulates principally in the phagocytic cells known as Gaucher ce Is.
In our case, a five-year old girl was admitted with seven days history of fever and abdominal distension. At physical examination the patient had hepatosplenomegaly. Laboratory tests revealed a hemoglobin concentration of 2.8g/L: platelet counts of 23,0001?l: normal range of white cell and differential counts, and negative Coombs' test. Liver enzymes were normal. For the evaluation of hepatosplenomegaly, fine needle aspiration was aerformed blindly against the palpable spleen. Wet-fixed hematoxylin and eosin-stained smears are made. The smears from the spleen showed predominantly macrophages with abundant cytoplasm and rather small, uniform, often eccentric nuclei with small nucleoli. The multinucleated cells were often found. The cytoplasm was pale, with more or less distinct fibrillarity. The cells had the characteristic appearance of Gaucher cells. Gaucher cells were also found it the tissue section from the liver, spleen and lymph node and the bone marrow aspirate. The diagnosis was later confirmed by determination of beta-glucosidase activity in peripheral blood leucocytes. Fine needle aspiration of the spleen is considered as a convenient procedure with a low complication rate for the diagnosis of lysosomal storage disease.

Abstract

- The cytologic findings of endodermal sinus tumor of the ovary are reported. The cytologic preperations were obtained from ascitic specimens. The findings on Papanicolaou-stained smears included a clean background and poorly preserved atypical cells loosely arranged in irregular or papillary groups. At high magnification, the cells had ill-defined and microvacuolated cytoplasms, with an increased nuclear-cytoplasmic ratio and prominent nucleoli. Hyaline globules characteristic of the alpha-fetoprotein (AFP)-synthesizing cells of endodermal sinus tumor were observed within the cells with periodic-acid-Schiff (PAS) stain. The presence of PAS - positive hyaline globules can be regarded, therefore, as a diagnostic clue to endodermal sinus tumor in an appropriate clinical setting and in the presence of AFP production. The cytologic findings in a cell block is important, in addition to smears, to obtain more diagnostic clues. A preliminary cytomorphologic diagnosis of this highly malignant tumor is valuable as a guide in planning further immunocytochemical and serologic studies.

Abstract
PDF
- A fine needle aspiration biopsy specimen of a retroperitoneal mass in a 26-year-old man who had had an orchiectomy for seminoma was submitted for cytologic evaluation. Cytologic features of the specimen included uniform neoplastic cells found singly or in groups of several cells intermingled with lymphocytes in a characteristic foamy, lacelike background. These cells varied from 10 to 20 m in diameter. The nuclei were round to ovoid with fine or reticular chromatin and one or more prominent nucleoli. The poorly defined cytoplasm stained pale-blue or blue with cytoplasmic vacuoles. The cytologic appearance was consistent with seminoma. Documented reports of the cytological appearance of seminoma are rare. The diagnosis of primary gonadal seminoma by fine needle aspiration biopsy is probably not indicated since the treatment of a primary gonadal tumor, regardless of its histogenesis, requires surgical resection. However, fine needle aspiration biopsy is extremely valuable in the diagnosis of extragonadal as well as metastic and recurrent seminoma.

- The eccrine poroma was described first by Pinkus et al. in 1956 as a subgroup of benign solid hidradenoma with the histologic structure resembling acrosyringium. The histologic appearance of eccrine poroma greatly resembles that of seborrheic keratosis and basal cell carcinoma. But the clinical lesion is fairly unique and the tumor is most commonly found almost exclusively on the foot, in the skin of the plantar surface. During the past four years, the authors experienced five cases of eccrine poroma which were diagnosed by histopathological examination of the tumor mass. All the cases occurred in the sole and lateral sides of the foot as well. Clinical and pathological features were reviewed and a brief review of the literatures was done.

- Neurosarcoidosis without systemic manifestation is vary unusual condition. Solitary lesion in the spinal dura is exceptional. The diagnosis of the neurosarcoidosis is very difficult, because the efficacy of Kveim test is low in neurosarcoidosis. The histologic examination is considered as confirmative diagnostic tool. The authors reported a case of neurosarcoidosis involving the dura of the cervical spine, in a fifty-nine year old female who had suffered from mid-back pain for six months and paraparesis for two weeks.
There was a dumbbell shaped mass in the D4-5 dura. It showed tan gray color with rubbery consistency. With histological examination, it revealed diffuse non-caseating granuloma.
Occasionally asteroid bodies were observed within the cytoplasm of the multinucleated giant cells. After operation, she was treated with steroid, and she has been well about nine month period.
