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

Systemic plasmacytosis is an uncommon disorder characterized by widely disseminated macular skin eruptions composed of polyclonal lymphoplasmacytic infiltrates associated with variable extracutaneous involvement. An aggressive clinical course has been observed in a small number of patients, but most cases have followed chronic and benign clinical course without spontaneous remission. Previously reported cases of this entity have been described almost exclusively in Japanese patients. We recently experienced a case of systemic plasmacytosis in a 48-year-old Korean female patient. Initial skin biopsy specimen revealed patchy perivascular and periadnexal infiltrates of mature plasma cells. Serum immunoelectrophoresis revealed polyclonal hypergammaglobulinemia, and polyclonal plasmacytosis was noted on the subsequent biopsy specimens of left supraclavicular and axillary lymph nodes. Multiple tiny pulmonary nodules appeared six years after the initial cutaneous presentation and were found to be of the same histologic appearance. We herein report a rare case of systemic plasmacytosis with a review of the literature.

Abstract PDF

Cutaneous myoepithelial neoplasms and papillary eccrine adenomas (PEA) are rare conditions. Malignant tumors within a PEA are even rarer, with only one case reported to date. Herein, we present an extremely rare case of a cutaneous myoepithelial carcinoma arising in a PEA in a 70-year-old man presenting a solid mass in the left buttock. Histopathologically, most of the resected tumor revealed features consistent with the diagnosis of PEA. Some small nests and nodules were intermixed with the PEA and were present adjacent to the PEA. The tumor cells of nests and nodules showed ovoid to spindle shaped nuclei and slightly eosinophilic cytoplasm. Immunohistochemically, they were positive for both epithelial and myogenic markers, consistent with myoepithelioma. An inguinal lymph node with a metastatic lesion showed the same findings of myoepithelioma despite inconspicuous atypia. Our case showed malignant transformation of the myoepithelial cells at the outermost layers of the PEA.

Abstract PDF: Acinic cell carcinoma(ACC) is the third common malignancy in major salivary gland. Fine needle aspiration cytology is a useful tool for the diagnosis of salivary gland lesions. However, some low grade malignancies, such as ACC and mucoepidermoid carcinoma show relatively high false negative rate, mainly due to deceptively benign cytomorphologic appearance. We experienced a papillary-cystic variant of ACC, having different cytopathologic features compared with those of classic ACC. Our case showed monolayered sheets and papillary clusters without any acinic structures or naked nuclei of the tumor cells. Foamy proteinaceous material was seen in the background. The tumor cells had a large amount of granular cytoplasm and eccentric nuclei. Many vacuolated or clear cells were also noted.

Abstract PDF: Trichoblastic fibroma is a benign trichogenic tumor that has both epithelial and mesenchymal components and exhibits partial follicular induction. We studied 4 cases of trichoblastic fibroma and reviewed their clinical and histologic features. Two tumors were present in the face. The remaining two were in the vulva and perianal area, respectively. The age of the patients ranged from 53 to 68 years, with an average age of 62. All were female. Histologically, the lesions showed a well circumscribed mass, located at dermo-subcutaneous junction in three patients and subcutaneous in one. They demonstrated mesenchymal induction evidenced by hair germ-like structure and perifollicular sheath. There was no connection between the tumor and epidermis. Differentiation toward hair structure led to the formation of the infundibulum through inner root sheath. Trichoblastic fibroma may be confused clinically and/or histologically with basal cell carcinoma. Identification of the mixed epithelial and mesenchymal components, and the absence of epidermal connection and cleft within the stroma are important in differentiating this benign neoplasm from basal cell carcinoma.

Abstract: Immature teratoma accounts for less than I percent of all ovarian teratomas and occurs commonly in young individuals, the peak incidence being in the second decade. It contains a variable mixture of mature and immature tissues in which neuroectodermal elements almost always predominate. Gliomatosis peritonei, miliary implants of mature glial tissues on the peritoneum or omentum, is an infrequently reported complication of mature or immature ovarian teratomas. We describe the first case in Korea of a 12-year-old girl with an immature teratoma and numerous glial peritoneal implants.

Abstract PDF: This report describes a case of ileal obstruction in a 31-year-old male with acute abdominal pain. A plain film of the abdomen showed segmental obstruction of small intestine. The patient underwent laparoscopic resection of the segment. Microscopic examination demonstrated foci of ulceration, submucosal edema, transmural inflammation, mural and neural hyperplasia and noncaseating granulomas, mimicking Crohn's disease. However, there were microabscesses predominantly composed of eosinophils. Furthermore, a section of an adult heterophyid trematode was identified in the crypt. Heterophydiasis usually causes diffuse enteritis. Therefore, this case with intestinal obstruction seems to be a rare manifestation of intestinal heterophydiasis.
