An endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare skin tumor that most commonly occurs on the eyelids of elderly women. This tumor is morphologically analogous to endocrine ductal carcinoma in situ and solid papillary carcinoma of the breast. We describe one case of a 51-year-old male with an EMPSGC co-existing with mucinous carcinoma of the eyelid. The tumor was composed of dilated ducts with a smooth border and was partially filled with a papillary proliferation. Tumor cells were uniform, small-to-medium in size, and oval-to-polygonal with light eosinophilic cytoplasm. Nuclei were bland with diffusely stippled chromatin and inconspicuous nucleoli. Tumor cells expressed chromogranin, synaptophysin, estrogen and progesterone receptors, cytokeratin 7, and epithelial membrane antigen.

Abstract PDF: Coccidioidomycosis, which results from inhaling the spores of Coccidioides species, is endemic in the southwestern United States. The primary infection site is the lung, and dissemination of the disease can occur. We report a case of cutaneous coccidioidomycosis in a 79-year-old Korean woman who presented with purpura on both lower extremities, but no pulmonary symptoms and no history of visiting an endemic area. Microscopically, skin biopsy showed multiple aggregates of granulomas in the dermis. Numerous multinucleated giant cells were associated with the granulomas. Mature and immature fungal spherules, which were 20 to 30 micrometer in diameter, were present inside and outside the multinucleated giant cells.

Abstract PDF: We report here on a case of fibrovascular polyp arising in the hypopharynx of a 62-year-old man. Laryngomicroscopic surgery with laser ablation was performed to excise the mass. Histopathologically, the surface of the polyp was covered with mature squamous epithelium. The polyp showed a characteristic lobular proliferation of mature adipose tissue that was separated by myxoid or collagenous connective tissue. Some scattered skeletal muscle bundles were seen in the central portions of the polyp and these bundles were surrounded by a concentric proliferation of the spindle cells; this was reminiscent of Pacinian corpuscles. Regarding their location and the intermingled pattern of proliferating tissues, it is more plausible that the skeletal muscle is a hamartomatous component rather than entrapped, preexisting tissue.

Abstract PDF: We describe a case of an infarcted adenomatoid tumor of the epididymis that was challenging to diagnose. A 20-year-old man presented with acute left scrotal pain. He was found to have a 2x1.5x1 cm tumor that was relatively well circumscribed on gross examination. There was a central necrotic area that exhibited gaping spaces and ghost outlines of epithelial cells. The periphery of the necrotic lesion showed focally viable adenomatoid tumor. The majority of the tissue adjacent to the necrosis consisted of granulation tissue, fibroblastic and myofibroblastic proliferation, and neutrophils. The fibroblasts and myofibroblasts showed plump nuclei, often with small nucleoli. No mitotic activity was present. The differential diagnosis for an infarcted adenomatoid tumor includes malignant mesothelioma, inflammatory myofibroblastic tumor, and inflammatory conditions. The key to diagnosing an infarcted adenomatoid tumor is to consider it in the differential diagnosis of any spindle cell tumor with necrosis occurring in the genital tract.

Abstract PDF: Vascular malformations associated with neoplasms are extremely rare. Herein we report an extraordinary coincidence of arteriovenous malformation (AVM) and gastrointestinal stromal tumor (GIST) in the jejunum. A 44-year-old woman presented with melena and anemia. Abdominal computed tomography revealed a highly vascularized, strong early arterial enhancing soft tissue mass in the jejunum, which was confirmed by angiography to be an AVM supplied by the distal jejunal branch of the superior mesenteric artery. An emergency operation was performed due to active gastrointestinal (GI) bleeding. The resected jejunum showed a protruding, mostly solid subserosal mass. The mass was confirmed to be a spindle cell type GIST and was intermingled with the AVM located in the overlying submucosa and muscularis propria. To our knowledge, this is the first reported case of an AVM associated with a GIST. This case masqueraded radiologically as an AVM alone and presented clinically with GI bleeding.

Abstract PDF

In an attempt to better define the cytologic characteristics of schwannomas, we have reviewed aspirates and corresponding histologic sections from 23 schwannomas. Of this number, the original cytologic diagnoses were: schwannoma in 14 cases (61%), benign soft tissue tumor in 2 cases (9%), and insufficient specimen in 7 cases (30%). The cytologic findings common to all cases of schwannoma included fragments of tightly cohesive fascicles with variable cellularity and corresponding Antoni type A area. The Antoni type B area, consisting of scattered spindle cells and some histiocytes and lymphocytes against a myxoid background, was seen in 14 cases. Fibrillary stroma was seen in 12 cases. The tumor cells had spindle- or oval-shaped nuclei, with pointed ends and indistinct cell borders. Nuclear palisading was seen in 10 cases, and distinctive Verocay bodies were seen in 5 cases. In ancient schwannomas, there were no Verocay bodies. Most schwannomas have distinct cytomorphologic features that allow correct diagnosis. The major problem with fine needle aspiration cytology of these tumors is the high frequency of poor cellularity, particularly in lesions with cystic degeneration. Of 7 cases with insufficient specimen, 4 showed marked cystic changes and 1 showed marked hyaline changes on histologic sections. In conclusion, we believe that if cytopathologist reminds the situation such as cystic degeneration or hyaline degeneration, the correct diagnosis of the schwannoma will be easily made.

Abstract PDF: BACKGROUND
The abnormal expression of c-kit is implicated in the pathogenesis of a variety of solid tumors. The Rb pathway and p53 act as cell cycle regulators. The purpose of this study was to assess the expression of c-kit, Rb, p53, p16 and cyclin D1 and their relationship to clinical and pathological parameters in patients with non-small cell lung carcinomas (NSCLC(s)).
METHODS
Tissue microarrays consisting of 2 mm cores from the corresponding blocks were constructed from 54 NSCLC(s). Immunohistochemical staining for c-kit, Rb, p53, p16 and cyclin D1 was performed. C-kit immunostaining was considered positive if > or =10% of tumor cells were immunoreactive along the membrane and/or in cytoplasm. For Rb, p53, p16 and cyclin D1, tumor cells showing a nuclear staining pattern were interpreted as positive.
RESULTS
We found that c-kit was expressed in 13 (24%) cases, Rb was lost in 39 (72%) cases, p53 was expressed in 28 (52%) cases, p16 was lost in 42 (78%) cases and cyclin D1 was expressed in 33 (61%) cases. The c-kit expression was significantly higher in adenocarcinoma (39%) than in squamous cell carcinoma (8%). We did not find any correlation between c-kit, Rb, p53, p16 and cyclin D1 expression and clinicopathological parameters such as: age, tumor size, lymph node involvement, disease stage and distant metastasis. There was a direct correlation between p53 expression and Rb loss.
CONCLUSIONS
These results suggest that c-kit may be a useful therapeutic target for patients with c-kit positive tumors, and that the disruption of Rb and p53 pathways may play an important role in the development and progression of NSCLC(s).

Abstract PDF: Urachal adenocarcinoma is a rare tumor, and it has similarities with nonurachal adenocarcinoma; therefore, it is sometimes difficult to make a diagnosis. We present a typical case of urachal adenocarcinoma that had all the diagnostic criteria including the presence of an urachal remnant. A 65-year-old woman presented with complaints of a painless gross hematuria. Pelvic CT and cystoscopy showed an intraluminal protruding mass centered in the bladder wall. When diagnosed as adenocarcinoma with a signet ring cell component being noted by frozen biopsy, partial cystectomy with resection of the median umbilical ligament and peritoneum was carried out for a suspected urachal adenocarcinoma. The tumor morphology showed as typical mucinous adenocarcinoma. Characteristic tubular structures showing the typical histology of an urachal remnant was found in the perivesical fat. On immunohistochemical staining, the urachal adenocarcinoma showed a pattern similar to colonic adenocarcinoma, while the urachal remnant showed strong positivity for CK7 and Chromogranin A.

Abstract PDF: BACKGROUND
The most consistent chromosomal abnormality in ependymomas, is loss of 22q (17-75%) and gain of 1q (0-50%). However, significance of this abnormality is uncertain.
METHODS
Genomic imbalances in 27 Korean ependymomas, including 21 low grade ependymomas, 4 anaplastic and 2 myxopapillary ependymomas, were analyzed by degenerate oligonucleotide primed-PCR-comparative genomic hybridization.
RESULTS
Common gains were found in 17 (63%), 20q (59%), 9q34 (41%), 15q24-qter (33%), 11q13 (30%), 12q23 (26%), 7q23-qter (26%), 16q23-qter (30%), 19 (26%), and 1q32-qter (22%). DNA amplification was identified in 12 tumors (44%). Chromosomal loss was a less common occurrence in our study, but was found in 13q (26%), 6q (19%), and 3 (11%).
CONCLUSION
The recurrent gains or losses of the chromosomal regions which were identified in this study provide candidate regions that may be involved in the development and progression of ependymomas.
