Herein we describe a rare case of acute appendicitis associated with localized aspergillosis in an 8-year-old boy with acute lymphoblastic leukemia. During chemotherapy, the patient complained of mild abdominal pain in the peri-umbilical area and displayed an increased C-reactive protein level. Abdominal ultrasonography disclosed appendicitis and consequently an appendectomy was done. Histologically, acute appendicitis and Aspergillus hyphae were identified in the lumen and necrotic mucosa. However, there was no evidence of systemic aspergillosis. While aspergillosis is a common fungal infection in immunocompromised patients treated with chemotherapy, acute appendicitis associated with localized aspergillosis without systemic infection is a very rare occurrence.

Abstract PDF

We describe here a 67-year-old man who was diagnosed with a rare case of intraductal papillary mucinous tumors that occurred simultaneously in the liver and pancreas. Abdominal computed tomography showed a tubular and cystic dilatation of the pancreatic duct in the pancreas tail, which suggested an intraductal papillary mucinous tumor (IPMT), and multiple intrahepatic duct stones. The patient underwent a distal pancreatectomy with splenectomy and a lateral segmentectomy of the liver. Microscopic examination showed an intraductal papillary mucinous neoplasms of borderline malignancy in the pancreas and a non-invasive intraductal papillary mucinous tumor with moderate dysplasia of the bile duct. Although several cases of intraductal papillary mucinous neoplasm of the liver (IPNL) without any pancreatic association have been described, the simultaneous presentation of both IPMT of the pancreas and IPNL is very rare. The patient has been doing well for 10 months postoperatively.

Abstract PDF

We present a case of mandibular involvement with Langerhans cell histiocytosis (LCH), diagnosed by ultrasound-guided aspiration and subsequently confirmed by incisional biopsy and immunohistochemistry in an eight-year-old boy. The cytologic findings included the presence of characteristic Langerhans cells of both mononucleate and multinucleate form. Diagnostic confirmation was obtained by immunopositivity for S-100 protein and CD1a of Langerhans histiocytes on paraffin-embedded sections obtained during incisional biopsy of the right mandibular area. By reporting a case of childhood LCH, we correlate the cytologic findings with histologic features and discuss the role of aspiration cytologic diagnosis in such a rare and cytomorphologically characteristic case.

Abstract PDF: We report a case of nasal chondromesenchymal hamartoma. A 14-year-old boy presented with a 5 cm sized mass in the left maxillary sinus, facial swelling and a loose tooth. A subtotal left maxillectomy with a bone graft was performed. The excised mass was composed of partly encapsulated, solid and cystic fragments of soft tissues. The mass contained chondroid and myxoid areas consisting of mesenchymal tissues including hyaline cartilage, osteoid and spindle cells in various proportions. The hyaline cartilage component was the most prominent. The spindle cell component had a fibrous matrix with variable myxoid or sclerotic changes. Thick hyalinized eosinophilic osteoid-like trabeculae were focally present. Immunohistochemically, all the mesenchymal cells tested positive for vimentin. The chondrocytes tested positive for the S-100 protein, and the spindle cell component showed focal immunoreactivity for smooth muscle actin and desmin. However, the cells were negative to pan-cytokeratin and p63.

Abstract PDF: Background
: Carcinoma of the pancreas is a fatal malignant disease with limited therapeutic options. Cyclooxygenase-2 (COX-2) and c-erbB-2 are known to be involved in the carcinogenesis, differentiation and invasiveness of various neoplasms. We studied the immunohistochemical expressions of c-erbB-2 and COX-2 and the correlation between these expressions and the clinicopathologic parameters and the relation between the expressions.
Methods
: Immunohistochemical staining for c-erbB-2 and COX-2 were performed on the paraffin embedded sections of 36 cases of surgically resected ductal adenocarcinoma of the pancreas and 10 cases of non-neoplastic pancreas tissue.
Results
: The non-neoplastic control group showed a c-erbB-2 expression in the acini (8/10) and ducts (2/10), and a COX-2 expression in the acini (6/10) and ducts (3/10). The overexpression of c-erbB-2 was observed in 58% (21/36) of the carcinoma specimens. No significant correlation was found between c-erbB-2 and age, gender, tumor size, gross type, histologic grade, vascular invasion, perineural invasion, lymph node metastasis, and the TNM stage. The overexpression of COX-2 was observed in 41.7% (15/36) of the carcinoma specimens. The COX-2 expression was significantly high in the lymph node metastasis group (p<0.05), but it was not correlated with the other clinicopathologic parameters. Also there was no significant correlation between the c-erbB-2 and COX-2 expressions.
Conclusions
: In pancreatic ductal adenocarcinomas, c-erbB-2 and COX-2 were frequently overexpressed, and COX-2 overexpression was correlated with lymph node metastasis.

Abstract PDF: Metastasis to the thyroid gland is very rare in clinical practice. We recently encountered a 65-year-old woman who presented with a large thyroid nodule that mimicked the cytologic features of a papillary thyroid carcinoma on fine needle aspiration biopsy (FNAB). Although initially diagnosed as a papillary thyroid carcinoma, a thorough clinical work-up revealed multiple lesions in the bones, liver, and nasal cavity, which were confirmed as metastases of a malignant melanoma. Despite a thorough physical examination, however, the primary skin lesion could not be identified. Although FNAB shows a high degree of accuracy in diagnosing primary thyroid tumors, it is less accurate in diagnosing metastases to the thyroid gland. A thorough clinical history with appropriate immunohistochemical staining assays is necessary for the accurate diagnosis of metastatic malignant melanoma.

Abstract PDF: In the investigation of superficial lymphadenopathy of unknown cause, fine needle aspiration (FNA) cytology plays an invaluable role. It enables the differentiation of benign lymphadenopathy from lymphoid and non-lymphoid malignancies, obviating the need for open biopsy, and allowing the triage of patients. Cytopathologists should be familiar with the typical FNA patterns of benign lymphadenopathy, and recognize and differentiate among categories. In a minority of cases of benign lymphadenopathy, FNA can render a specific diagnosis. Benign lymphadenopathies are generally categorized into reactive lymphoid hyperplasia (RLH), inflammatory or infectious processes, and benign lymphoproliferative disorders. RLH characteristically presents with a heterogeneous and polymorphous smear composed of normal cellular constituents of lymph nodes, in contrast with the homogeneous or monomorphic smear of most lymphomas. The caveat is that various malignant disorders may also present with polymorphous populations. It is also important to recognize thatbenign lymphoid smears may sometimes contain atypical cells that raise the suspicion of malignancy. Clinical information should always be the integral part of the diagnostic criteria in FNA of lymphadenopathy. If there is any doubt about the benign nature of the smear, it is prudent to suggest biopsy and ancillary studies.

Superficial Endometriosis of the Uterine Cervix as a Source of Atypical Glandular Cells of Undetermined Significance in the Cervicovaginal Smear: A Report of Two Cases.: Hye Jeong Choi, Seung Koo Lee, Kyu Rae Kim; Korean J Pathol. 2001;35(3):263-266.

Abstract PDF: Superficial endometriosis of the uterine cervix refers to a lesion in which endometrial stroma and/or gland is located immediately subjacent to the surface epithelium. The cells on the cervicovaginal smear shed from the lesion can be a significant source of atypical glandular cells of undetermined significance (AGUS), or can be easily mistaken for glandular dysplasia or adenocarcinoma in situ. Not infrequently it occurs at the conization site for cervical neoplasia. We describe the cytologic and histologic features of 2 cases of superficial endometriosis of the uterine cervix, which were discovered during an evaluation for AGUS detected on the cervicovaginal smears, with an emphasis on the utility of trichrome and reticulin staining for the diagnosis of superficial endometriosis. The cervicovaginal smears show sheets and clusters of glandular cells having mild to moderately pleomorphic oval nuclei with inconspicuous nucleoli and indistinct cytoplasmic border. Single cells or tumor diathesis were not present. Diagnostic histologic findings were the absence of thick or abundant collagen bundles, the encasement of individual stromal cells by a fine reticulin network and thick reticulin fibers around the spiral arterioles within the endometriotic foci. Therefore, superficial endometriosis should be considered as a potential source of AGUS, especially during follow-up after conization for cervical intraepithelial neoplasia.

Abstract PDF: Cellular angiofibroma is a recently described, distinctive soft tissue tumor of the vulvovaginal region which is characterized by small, well-circumscribed tumors with fibroblastic differentiation. We report three cases of cellular angiofibroma of the vulva in middle-aged women. All three patients presented with painless swelling in the labium majora. The age of the three patients ranged from 43 to 56 years old (mean: 48 years old) and the size of the tumor ranged from 2 to 5 cm. The microscopic appearance was characterized by a cellular, well-circumscribed mass composed of uniform, bland, spindle stromal cells, numerous thick-walled, hyalinized vessels, and a scarce component of mature adipocytes. Immunohistochemical stains of the tumor cells show positivity for vimentin but negativity for smooth muscle actin, S-100 protein, desmin, factor VIII-related antigen and epithelial membrane antigen. The tumor should be differentiated from aggressive angiomyxoma and angiomyofibroblastoma because of its different clinicopathologic features, cells of origin and immunohistochemical findings.

Abstract PDF: We report a case of mucinous cystadenoma of uncertain malignant potential and carcinoid of appendix associated with bilateral mucinous cystadenoma of ovary and pseudomyxoma peritonei. The patient was a 46-year-old female. She suffered from dyspnea and lower abdominal palpable masses for several months. Ultrasonogram showed multilocular huge ovarian cysts. Appendectomy, transabdominal hysterectomy, bilateral salphingo-oophorectomy and biopsy of omentum were performed. The bilateral ovaries measured 16 11 cm and 7X5 cm in size, respectively. The both ovaries showed multilocular cysts filled with thick mucus material. The ovarian cysts were covered by a single layer of columnar epithelium with focal proliferation. Mucus materials dissected through the ovarian stroma (pseudomyxoma ovarii). The tip of appendix was dilated and covered by mucus material. The cut surface showed a cyst and a yellowish solid mass proximal to the cyst. Microscopically, the appendiceal cyst was lined by stratified columnar epithelium with moderate cytologic atypia. Mucus material dissected through the wall. In the proximal portion of the appendix, a classic carcinoid with focal tubular form was present in submucosa and muscle layer. The omentum was covered by thick mucus material. Microscopically, the omentum showed mucinous epithelium and mucus material (pseudomyxoma peritonei).

Abstract PDF: Intraosseous lipoma is a very rare primary tumor of the bone. We report four cases of intraosseous lipoma. The patient ranged in age from 34 to 59-year-old (median age: 35 year-old). There were three men and one woman. All of four cases presented with pain. The involved bones were calcaneus in two cases, tibia in one case and ilium in one case, respectively. In all cases plain x-ray film revealed well-defined lytic lesion. Their size ranged 2 to 4.5 cm (mean size: 3.5 cm). Histologic examination showed mature adipose tissue. Three cases showed secondary changes such as atrophic bone, fat necrosis, fibrosis, dystrophic calcification, and reactive ischemic bone formation. The clinicopathologic and roentgenographic correlation are necessary in establishing correct diagnosis of this tumor.
