BACKGROUND
The Korean Bone and Soft Tissue Pathology Study Group of the Korean Society of Pathologists conducted a nationwide retrospective analysis of soft tissue sarcoma (STS) to provide the clinicopathologic characteristics of STS within the population of the Republic of Korea.
METHODS
The cases of STS were collected during a 7-year period (2001-2007) from 19 institutes in Korea. All cases were classified according to the histologic criteria proposed by the World Health Organization. Clinicopathologic data were reviewed.
RESULTS
Data from 722 patients (median age, 50 years) were collected. Data showed a slight male predominance. The most frequent types of STS in decreasing order were liposarcoma, malignant fibrous histiocytoma, leiomyosarcoma, and synovial sarcoma. STS occurred throughout the body, although approximately half (47.8%) were located in the extremities. The majority of STS was histologically classified as high grade with a large tumor size (>5 cm). The overall survival rate for the patients was 76.3% (median follow-up time, 26 months; range, 1 to 89 months). Histologic grade, tumor size, American Joint Committee on Cancer stage, tumor site, and resection status were prognostic. Significant independent adverse prognostic factors were large tumor size (>5 cm) and tumor site other than extremities.
CONCLUSIONS
We reported the distribution and characteristics of STS in the Republic of Korea.

Abstract PDF: We present the cytologic findings observed in a fine needle aspiration biopsy specimen of a rare myxoid variant of leiomyosarcoma with epithelioid features and the tumor had metastasized to the abdominal wall. The aspirate showed hypercellularity in a hemorrhagic background. Some large 3-dimensional aggregates of spindle cells were observed. Each cell had a solitary ovoid-to-elongated nucleus with finely granulated chromatin, one or two small distinct nucleoli and an irregular nuclear membrane. There were irregular fascicles of spindle cells with cigar-shaped, blunt-ended nuclei admixed with inflammatory cells. Epithelioid cells with a rather narrow, dense cytoplasmic rim and a well-defined cell border were embedded in a myxoid matrix in a cord-like and cluster arrangement. The matrix appeared as a pale green substance with sharply defined edges. There were very few mitoses. These cytologic features were the same as those of a uterine myxoid leiomyosarcoma that was surgically excised 7 years ago, and immunohistochemical staining revealed the smooth muscle origin of the tumor.

Loss of Heterozygosity on Chromosome 15q15 Near Thrombospondin-1 Gene in Breast Carcinomas.: Jeana Kim, Kyoung Mee Kim, Heejeong Lee, Kyungji Lee, Mun Gan Rhyu, Anhi Lee, Seok Jin Kang, Kyo Young Lee; Korean J Pathol. 2009;43(3):221-230.; DOI: https://doi.org/10.4132/KoreanJPathol.2009.43.3.221

Abstract PDF: BACKGROUND
Chromosome 15q15 near the thrombospondin-1 (THBS-1) gene may be associated with tumor progression and metastasis. To clarify the potential role of the15q15 region in progression of breast carcinoma, we investigated the loss of heterozygosity (LOH) and the microsatellite instability (MSI) status of chromosome 15q15. Methods : LOH and MSI were detected in 84 breast carcinoma specimens using PCR-based microsatellite analysis with three microsatellite markers.
METHODS
LOH and MSI were detected in 84 breast carcinoma specimens using PCR-based microsatellite analysis with three microsatellite markers.
RESULTS
Of 77 breast carcinomas containing the heterozygous alleles, 25 (32%) showed LOH in at least one microsatellite marker. Partial LOH and total LOH were detected in 14 (18.27%) and 11 (14.3%) cases. The total LOH were inversely correlated with node metastasis. A single LOH at D15S514 was inversely correlated with nuclear grade and a single LOH at the D15S129 allele was associated with increased expression of the THBS-1 gene. MSI-positive breast carcinomas detected in 14 (17%) cases showed no correlation with any clinicopathologic feature.
CONCLUSIONS
These results indicate that loss of the chromosome 15q15 region delays the progression of breast carcinoma because the magnitude of LOH is large and involves the THBS-1 gene and additional genetic elements. The genes located on chromosome 15q15 probably play a tissue-type-dependent role in malignant growth of the tumor.

Abstract PDF: BACKGROUND
The incidence of Crohn's disease in the upper digestive tract, and especially in the stomach, is recently increasing. Focal inflammatory reaction without Helicobacter pylori (H. pylori) infection is thought to be the characteristic pathologic findings suggesting Crohn's disease in the stomach. Yet gastric involvement of Crohn's disease has not been studied in Korea. We studied the endoscopic and pathologic findings of patients with Crohn's disease in the stomach by taking biopsies.
METHODS
Thirty patients with Crohn's disease who underwent gastroduodenoscopy followed by biopsies were included in the study. The pathology of the gastric biopsy specimens and the presence of H. pylori were evaluated.
RESULTS
Among 30 cases, 22 cases (73.3%) were H. pylori negative and 8 cases (26.7%) were H. pylori positive. For the H. pylori negative cases, all but one cases showed pit abscess and focal lymphocytic collections in the antrum. Granulomas were found in 6 cases (20%) and they were exclusively located in the antrum.
CONCLUSIONS
In the stomach, pit abscess and focal lymphocytic collections that are not associated with H. pylori infection are the characteristic pathologic findings found in Crohn's disease.

Abstract PDF: BACKGROUND
Matrix metalloproteinase-9 (MMP-9) is a matrix-degrading enzyme that's believed to play a crucial role not only for tumor invasion and metastasis, but also for a variety of stromal reactions, including neovascularization. The aim of this study was to investigate the expression of MMP-9 and to compare its expression with the angiogenesis activity in human osteosarcoma.
METHODS
Archival tumor tissue samples from 20 patients with osteosarcoma were analyzed by performing immunohistochemistry for the expression of MMP-9 and CD34. The vascularity was measured as the average microvascular density (MVD) of the CD34-positive vessels. The clinical information was obtained through searching the computerized retrospective database from the tumor registry.
RESULTS
MMP-9 was expressed in 90% (18/20) of the tumors we examined. The MVD ranged from 10.5 to 179.7 with a mean of 64.9. There was no significant correlation between the MMP-9 expression and the MVD (p=.613). The MMP-9 expression was not associated with any of the clinicopathologic variables, whereas the MVD showed an increasing tendency according to the metastasis status (p=.073).
CONCLUSIONS
We demonstrated that MMP-9 activation is likely to occur in human osteosarcoma. However, there was no direct involvement of MMP-9 with tumor angiogenesis. It is noteworthy that MVD may aid physicians to predict the presence of distant metastasis in osteosarcoma patients.

Abstract PDF: Inflammatory (xanthomatous) pseudotumors of the breast are very rare and this case is the first reported case in Korea. A healthy, pregnant 29-year-old woman presented with a right breast mass. Ultrasonography of the breast revealed a 1.8 x 1.9 x 1.1 cm, sized lobulated, partially spiculated mass in the upper and outer quadrant of the breast. Macroscopically, the mass was well circumscribed, bright yellow, and lobulated. Microscopically, the tumor was composed of foamy histiocytes with multifocal neutrophilic infiltration, accompanying chronic inflammatory cellul infiltration, fibrosis and ductal-lobular atrophy.

Abstract PDF: Aspergillous hypophysitis is an unusual cause of sella turcica enlargement, and this malady has a clinical presentation as a pituitary tumor, and especially as a pituitary adenoma. We report here on a case of aspergillous hypophysitis that developed in a 37-year-old healthy woman. She first experienced a blurred vision with amenorrhea and galactorrhea. Three months later, the CT scan revealed an intrasellar mass. The patient underwent a transsphenoidal exploration of the sella turcica for a presumed pituitary tumor. Histologically, the pituitary displayed necrotizing granuloma with the acutely branching fungal hyphae of Aspergillus.

Abstract PDF: Primary clear cell adenocarcinoma of uterine cervix is rare and cytomorphology in the vaginal smear have not been previously described in Korean literatures. The cytologic characteristics of clear cell adenocarcinoma of the uterine cervix include : malignant cells with abundant, finely vacuolated cytoplasm ; hobnail appearance ; and distinctive basement membrane-like hyaline materials within cellular aggregates. A 36-year-old woman presented with vaginal bleeding. Cytologic examination of vaginal smear and histopathologic examination of a radical hysterectomy specimen allowed the diagnosis of hemorrhagic tumor in the uterine cervix as a clear cell adenocarcinoma. Cytologic findings were very characteristic. The tumor cells had abundant, pale, finely vacuolated cytoplasm with indistinct cytoplasmic membrane. The nuclei were round to oval with finely dispersed chromatin. Extracellular basement membrane-like hyaline substance, which stained a light green color in Papanicolaou's preparation, was frequently observed within the cancer cell clusters.

Abstract PDF: Development of an invasive squamous cell carcinoma within a branchial cleft cyst (branchiogenic carcinoma) is very rare and this case is the first description of cytologic findings in Korea. A 62-year-old man presented with a 5-month history of an enlarged right neck mass. Fine needle aspiration cytology of the mass showed low cellularity and the background containing proteinaceous debris, inflammatory cells, and histiocytes suggested a cystic nature. Abundant lymphocytes, a few anucleated squames, and rare atypical squamous cells with pyknotic nuclei and abnormal keratinization were also noted. After excision of the mass, histologic findings were consistent with a branchiogenic carcinoma. We recommend to raise the possibility of carcinoma (primary or metastatic) when we observe a few dyskeratotic cells in a cystic mass within the neck area, especially in an old male.

Abstract PDF: Primary adenocarcinoma of the seminal vesicle is an extremely rare tumor, and its prognosis has been known to be poor. Herein, we report an adenocarcinoma of the seminal vesicle. The patient was a 50-year-old man who complained of a two-month history of terminal hematuria and lower abdominal discomfort. A pelvic magnetic resonance imaging study. Indicated a seminal vesicle cyst with focal intraluminal growth. Right seminal vesiculectomy was performed. Grossly, the seminal vesicle revealed a markedly cystic change with focal, friable, intraluminal papillary growth. The intraluminal mass showed a noninvasive adenocarcinoma with a tubular and tubulopapillary pattern, accompanied by necrosis. Immunohistochemically, the tumor was positive for cytokeratin and carcinoembryonic antigen and negative for prostate specific antigen and prostatic acid phosphatase.

Abstract PDF: Trichogenic tumors are a very rare group of primary cutaneous neoplasms and a few tumors have been recognized. Trichofolliculoma is a benign, papular, organoid adnexal tumor of the skin and presents as a solitary skin-colored nodule. We report six cases of trichofolliculoma occurred in Korean patients consisting of three male and three female patients. The duration of disease was variable from 3 months to 5 years. The site of tumor was limited to the face and included eyelid in two cases, nose in two cases, cheek and posterior aspect of ear in each one case. The size of the mass varied from 4 to 8 mm in diameter. Microscopically, all the cases showed large central cystic hair follicle with numerous secondary follicular buds, producing a radiating pattern. The stroma was fibrotic and well demarcated from the adjacent dermis.

Abstract PDF: During tumor progression, a subset of cells acquires metastatic properties, presumably through a series of genetic alterations. CD44 variant glycoproteins containing sequences encoded by exon v6 are related to tumor progression of human colorectal cancer. But their expression in normal colonic epithelium is controversial and studies of CD44 on each step of colorectal carcinogenesis are scanty. We studied CD44v6 expression in the normal colonic mucosa, adenoma, carcinoma in situ, and invasive colorectal carcinomas of different Astler-Coller stages. Endoscopically or surgically resected 36 normal colonic mucosa, 19 adenomas, 8 cases of carcinoma in situ, and 25 cases of carcinoma were selected. After immunohistochemical stain with CD44v6 antibody, positivity was graded as 0 to 4 based on the estimated percentage of positively stained tumor cells. The intensity of positive staining cells was also graded as 0 to 3. In all but one cases (97.2%), normal colorectal mucosa was negative for CD44v6. Positive rates in adenoma, carcinoma in situ, Astler-Coller stage A/B and C/D carcinoma were 73.6%, 88.9% and 87.5%, respectively. There was no statistically significant difference in the positivity between these groups. The staining intensity was significantly higher in the cases of stage C/D carcinoma group than those of adenomas (p<0.05). The percentage of positivity for CD44v6 was higher in stage C/D carcinoma group than adenoma, carcinoma in situ, and stage A/B carcinoma group (p<0.05). Expression of CD44v6 in the normal colonic mucosa was extremely rare and the positivity was increased according to the progression of colorectal tumors. Furthermore, it is more important to interpret the CD44v6 positivity according to the estimated percentage of positively stained tumor cells.

Abstract PDF: Adenoid cystic carcinoma constitutes 4 percent of all benign and malignant epithelial salivary gland tumors and is a highly malignant tumor of the salivary glands. The cytologic presentation in aspirates is usually characteristic with spherical clusters(balls) of small tumor cells filled with hyaline material. But in case of the poorly differentiated variety(solid type), it is difficult to differentiate from other tumors because sheets of small, fairly monotonous malignant cells, with somewhat larger and more conspicuous nuclei are only seen. The cytologic findings of fine needle aspiration of solid type adenoid cystic carcinoma of buccal mucosa in a 51-year-old man are presented. On cytologic findings, solid sheets of monotonous tumor cells with focal necrosis was noted on a hemorrhagic background and the characteristic cytologic features of adenoid cystic carcinoma was absent.

Abstract: This report presents an unusual case of primary malignant melanoma in the midesophagus. The patient was a 36-year-old woman presenting with dysphagia and odynophagia. The resected esophagus and proximal stomach showed a dark purple large polypoid mass, measuring 6.0 3.3 2.0 cm, with a diffuse tan pigmentation of surrounding mucosa in the mid-esophagus and two small daughter nodules, up to 1.2 0.3 cm, in the lower esophagus near the gastro-esophageal junction. A microscopic examination revealed a malignant melanoma of epithelioid cell type confined to mucosa and submucosa with a diffuse melanosis. Cytoplasmic immunoreactivity for HMB 45 and S-100 protein were noted. An electron microscopic examination revealed large, loosely cohesive variable shaped cells with a few cytoplasmic premelanosomes.

Abstract: Adrenal pseudocysts are rare benign cystic lesions resulting from a hemorrhage into a normal parenchyme of the adrenal gland. Although the frequency of adrenal cysts are increasing due to improved radiologic imaging techniques, only two cases have been reported in Korean literatures. A 63-year-old man was presented with a 10-year history of a mass in the right abdomen. Abdominal computed tomogram and a magnetic resonance image study showed a 9 cm sized well defined heterogeneous low attenuated mass in the right suprarenal area. Gross examination revealed an ovoid rubbery mass measuring 10 9 8 cm and weighing 355 gm. The content of this lesion was tan to deep brown, necrotic, and creamy with myxoid areas. Histologic examination revealed compressed, thin layers of adrenal cortex embedded in the fibrous tissue, and the cystic contents were eosinophilic fibrinoid materials with a few dilated cavernous vascular spaces lined by endothelial cells.

Abstract: Leiomyomas are benign tumors of smooth muscle origin and are very rare in the female genital tract. To date, approximately 35 cases of urethral leiomyoma have been reported in the literature. A 34-year-old woman presented with a 3-year history of a mass at the urethral meatus. Physical examination showed 2 x 1.5 cm lump at the urethral meatus, posterior lip. Histologically the tumor was mainly composed of benign cigar shaped smooth muscle izells which were arranged in interlacing fascicles without cellular atypia or mitosis. Immunohistochemistry confirmed leiomyoma with positive staining for vimentin, desmin and muscle specific actin.

Abstract PDF: Helicobacter pylori(H. pylori) infection is considered the most important cause of chronic active gastritis and peptic ulcer. To determine the prevalence, distribution and it's relationship to degree of inflammation, gastric biopsy specimens were obtained from 331 nonulcer dyspepsia(NUD) patients consisting of 52 H. pylori negative normal volunteers and 279 H. pylori infected patients. Lymphoid follicles, degree of acute and chronic inflammation(Grade 0 to 3), and degree of H. pylori(Grade 0 to 4) were observed. The prevalence of H. pylori in NUD was 84.29%. The lymphoid follicles were found in 138 patients(41.7%) and only 5 patients(l.5%) without H. pylori showed lymphoid follicles. There was strong a relationship between lymphoid follicles and degree of acute and chronic inflammation and intensity of H. pylori infection(P<0.001). Acute and chronic inflammation were more serious in the antrum than body in H. pylori infected patients. There was no relationship between lymphoid follicles and the site in the stomach of H. pylori infection(P<0.078), but the body portion had an increased frequency of lymphoid follicles compared to the in antrum. Our results indicate that the prevalence of H. pylori infection in Korea is higher than in Western people and the degree of acute and chronic inflammation are strongly correlated with the presence of lymphoid follicles. The lymphoid follicles are believed to be absent from the normal stomach and their presence is strongly associated with H. pylori infection. The fact there is an that increased frequency of lymphoid follicles in H. pylori infected patients, and that they are more prevalent in the body of the antrum, support the concept that H. pylori may be a precursor in the development of primary gastric lymphoma.

Abstract PDF: Teratocarcinoma is a form of mixed germ cell tumor composed of a mixture of teratoma and embryonal carcinoma. It is rarely found in the brain, but when present it is most commonly found in the pineal region. We investigated a case of primary teratocarcinoma in the pineal region. The patient was a 10 year old boy who had suffered from a bitemporal headache for one month. Brain CT and MRI revealed a rather well defined ovoid heterogenous mass in the pineal gland region, measuring 4.3 x 3.8 x 3.0 cm in size. Microscopically the tumor contained areas of immature teratoma and embryonal carcinoma. Immunohistochemical staining revealed positive reactions for cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, and alpha-fetoprotein in the embryonal carcinoma component.

Abstract PDF: Eosinophilic cellulitis is a rare dermatosis first described by Wells, and characterized by recurrent episodes of sudden outbreaks of erythematous cutaneous swellings often painful or pruritic. Microscopically, the lesion shows diffuse tissue eosinophilia and fibrinoid flame figures, evolution of associated focal necrobiosis, and formation of focal microgranulomas associated with eosinophils. The cause is still unknown but the triggers which have been thought to precipitate the disease include insect bites, parasitic infections such as toxocara, onchocerciasis, nasopharyngeal carcinoma, rheumatoid arthritis and spider bites. However many cases are idiopathic. The author experienced a case of eosinophilic cellulitis of a 52-year-old woman with multiple cutaneous tender plaques of cellulitis for approximately 10 years with history of repeated remission and recurrent episodes. Biopsy was taken from ulcerated edematous nodule of inguinal region under the clinical impression of deep fungal infection, pyoderma gangrenosum and polyarteritis nodosa. Cultures for fungal and common organisms were negative. Histologically, the entire dermis was infiltrated by numerous eosinophils and scattered histiocytes. There were scattered flame figures showing necrobiotic foci in the collagen with accumulation of eosinophils, granulated free cosinophilic granules and histiocytes.

Abstract PDF: The glomus tumor or glomangioma is an uncommon benign tumor that arises from the modified smooth muscle cells of the glomus body, a neuromyoarterial receptor sensitive to temperature, that regulates arterial flow. It is most commonly found in the skin particularly in the nailbeds or fingertips, but approximately 70 cases described in the stomach. The author experienced a glomus tumor of the stomach was found in a 43 year old female patient who had discomfort in upper abdomen for 40 days. Clinically, this uncommon gastric tumor mimics most of the benign and malignant lesions of the stomach and the most important aspect of this tumor is its histologic identification and differentiation from the more common gastric lesion. Microscopically the tumor was composed of cellular lobules of various sizes separately by irregular fibrous and muscular trabeculae. Ultrastructural study showed basal lamina, pinocytotic vesicles and numerous subplaomalemmal plaque.
