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 report a case of chondroblastoma arising in the lumbar spine in a 25-year-old man who presented with low back pain of 5 years duration. Plain radiography and computed tomography revealed a well-defined osteolytic mass surrounded by marginal sclerosis in the third lumbar vertebra. The mass encroached on the left neural foramen on magnetic resonance imaging. Histologically, the tumor consisted of round to oval cells with eosinophilic cytoplasm and randomly scattered osteoclastic type giant cells. There were characteristic chicken-wire calcification and aneurysmal bone cyst-like changes. Chondroblastomas of the lumbar spine are extremely rare, and only nine cases have been reported. Spinal chondroblastoma should be distinguished from other benign bone tumors, because it tends to show aggressive biological behavior with high recurrence and mortality rates.

Abstract PDF

We describe a 69-year-old woman who presented with a dedifferentiated extraskeletal myxoid chondrosarcoma arising in the left masticator space. Computed tomography and magnetic resonance imaging revealed a 5 cm sized mass in the left masticator space. Histologically, the tumor consisted of two distinct areas. The less cellular area was a low-grade extraskeletal myxoid chondrosarcoma, composed of strands or cords of uniform spindle cells and abundant myxoid stroma. The more cellular, dedifferentiated area corresponded to a high grade myxofibrosarcoma, consisting of anaplastic tumor cells in myxoid stroma and geographic necrosis. The tumor cells of the former area were positive for S-100 protein, microtubule-associated protein-2 (MAP-2) and class III beta-tubulin, but negative for cytokeratin, smooth muscle actin, and desmin. The tumor cells in the latter, pleomorphic area showed MAP-2 and beta-tubulin immunoreactivity with a high Ki-67 labeling index. Based on its histologic and immunohistochemical features, the tumor was considered a dedifferentiated extraskeletal myxoid chondrosarcoma.

Abstract PDF

Solitary fibrous tumor (SFT) is a benign mesenchymal neoplasm usually occurring in the pleura. Kidney is one of the rarest sites for SFT. We report here on two cases of renal SFT found in 30-year-old and 33-year-old men with review of the literatures. Both cases manifested as well-enhanced solid masses in kidney and radical nephrectomies were done. The tumors consisted of bland-looking spindle cells arranged in short, ill-defined fascicles and storiform pattern with characteristic hemangiopericytoma-like blood vessels. The tumor cells were strongly positive for CD34 and CD99, focally positive for bcl-2, and negative for cytokeratin and human melanoma black-45 on immunohistochemical stainings. Possibility of SFT should be considered in the differential diagnosis of a renal mass which consists of benign-looking spindle cells and hemangiopericytomatous blood vessels. Immunohistochemical staining for CD34 is essential to confirm the renal solitary fibrous tumor.

Abstract PDF: We report here on a case of combined hepatocellular and cholangiocarcinoma (CHC) with neuroendocrine differentiation and sarcomatoid transformation. A 59-year-old male who had had HBV-associated chronic liver disease presented with hepatic masses. The explanted liver showed three small masses, two in the right lobe and one in the left lobe. The largest one in the right lobe was a 2.0 cm sized binodular mass,consisting of a yellowish tan nodule and an abutting reddish brown nodule. Microscopically, the reddish brown nodule was a cholangiocarcinoma (CC) showing neuroendocrine differentiation and sarcomatoid tranformation. The yellowish tan nodule and the remaining two masses were hepatocellular carcinoma (HCC)s. On immunohistochemistry, both the adenocarcinoma and spindle sarcomatoid cells were positive for pancytokeratin, but only the adenocarcinoma cells were positive for chromogranin and carcinoembryonic antigen (CEA). Mitotic and Ki67 labeling indices as well as p53 immunopositivity were significantly increased only in the CC component. We report here on the first case of CHC in which the CC displayed neuroendocrine differentiation and sarcomatoid transformation with high mitotic and Ki67-labeling indices, as well as having p53 overexpression.

Abstract PDF: Primary mucinous cystic neoplasms of the retroperitoneum in women are rare and show histologic features similar to their ovarian or pancreatic counterparts. We present three cases of primary retroperitoneal mucinous neoplasms of variable malignant potentials including a cystadenocarcinoma in a 50-year-old woman, a cystic neoplasm of borderline malignancy in a 31-year-old woman, and a cystadenoma in a 67-year-old woman. All cases showed histologic features similar to mucinous tumors of the ovary. Immunohistochemical study demonstrated positivity for calretinin in case 3. The histogenesis of these neoplasms can be assumed most likely to be mucinous metaplasia of the mesothelium or undetected heterotopic pancreatic tissue. Appropriate management is thought to be the same as for analogous ovarian neoplasms.

Abstract PDF: Although the liposarcoma is a common malignant mesenchymal tumor of the retroperitoneum, its occurrence in the kidney is very rare. A few cases involving only the renal parenchyma have been reported. The histologic features of these cases are not different from those of other body sites. We report a case of pleomorphic liposarcoma arising in the kidney of a 36-year-old man. He had been suffering from pain in the right flank for two weeks. A computed tomographic scan demonstrated a large mass in the right kidney. He underwent a radical nephrectomy under the clinical impression of renal cell carcinoma. There was a 11 cm-sized well demarcated solid mass in the lower pole of the right kidney. Microscopically, the tumor consisted of pleomorphic spindle and epithelioid cells with focal areas showing distinct adipocytic differentiation and geographic necrosis. A few diagnostic lipoblasts were present. Despite extensive search on samples, no carcinomatous component was found. Immunohistochemically, all of the tumor cells were negative for cytokeratin but positive for vimentin. Lipoblasts were positive for S-100 protein as well as for vimentin. When the kidney tumor is exclusively sarcomatous, a generous sampling with proper immunohistochemical staining is recommended to differentiate a primary sarcoma of the kidney from a sarcomatoid carcinoma.

Abstract PDF: Gonadoblastoma is a neoplasm containing an intimate mixture of germ cells and elements resembling immature granulosa or Sertoli cells. It has been considered as in situ germ cell malignancy that can be overgrown by more malignant germ cell neoplasms. The tumor has been reported to almost exclusively develop in various types of gonadal maldevelopment syndromes containing the Y chromosome, such as in pure or mixed gonadal dysgenesis and, less commonly, in male hermaphroditism. However, occurrences in phenotypically and chromosomally normal, menstruating women are exceptionally rare. We report two cases of gonadoblastoma overgrown by dysgerminoma occurring in the ovaries of phenotypically and cytogenetically normal menstruating women. One of the two cases showed an area composed of granulosa cell tumor-like elements. This type of combination has been very rarely described, and exemplified that gonadoblastoma may progress to sex cord-stromal tumors as well as to the malignant germ cell tumors.

Abstract PDF: Splenic lymphangioma is a very rare and benign neoplasm. We report three cases of splenic lymphangiomas found in three women aged 71-years-old, 50-years-old, and 46-years-old. All of the three cases consisted of solitary lesions in the spleen and they were not represented as a part of lymphangiomatosis. Splenectomies were done in all cases and enlarged spleens revealed multicystic masses with variable-sized cysts. Histologically, the cysts were lined by flat endothelial cells and filled with acellular pinkish fluid. The cyst walls mainly consisted of hypocellular fibrous tissue with occasional smooth muscle components. The walls were shared by neighboring cysts, or intervened by interspersed splenic parenchymal components. On immunohistochemical stainings, the lining cells were diffusely positive for CD31 and factor VIII-related antigen (FVIII-RAg), while focally positive for CD34 in all cases.

Abstract PDF: Fibrolamellar carcinoma (FLC) is a rare variant of hepatocellular carcinoma (HCC). A 26-year-old female presented a hepatic mass and mild elevation of liver enzymes. Viral markers were negative, and levels of tumor markers were normal. Radiologically, the mass was well demarcated with central dot-like calcification and hypervascularity. Under the diagnosis of hepatocellular carcinoma, right lobectomy was performed. The tumor was grayish yellow with central fibrosis and focal hemorrhage and invaded a septal bile duct. Non-neoplastic liver was unremarkable. Microscopically, the tumor consisted of large polygonal cells in sheets, cords, and pseudoglands that were interwound by dense collagenous stroma. Tumor cells had abundant deeply eosinophilic cytoplasm and large nuclei with prominent nucleoli. Intracellular bile pigments and pale bodies were present. Tumor cells were diffusely immunostained for cytokeratin 7 (CK7), but not for cytokeratin 20 (CK20). Strong expression of CK7 in the present case suggests dual differentiation of FLC.

Abstract PDF: Tailgut cyst of retrorectal space is uncommon and its classification and prognosis are unclear. The lesion usually consists of a multiloculated cyst lined by squamous, transitional, and glandular epithelium. Disorganized fascicles of smooth muscle may be seen in the wall. Glomus coccygeum, normally located at the tip of coccyx, is incidentally discovered in the presacral mass including tailgut cyst. We report a case of tailgut cyst in a 35 year old female who had internal hemorrhoid and intermittent anal pain for 3 years. Pelvic computerized tomography revealed a 3x2 cm sized mass in the presacral area. The mass was multicystic and lined by squamous, transitional, and peudostratified ciliated columnar epithelium with inflammatory cells and scattered smooth muscle in the wall. Dermal adnexal structures were not present, which excluded dermoid cyst. A glomus body was identified in the surrounding soft tissue.

Abstract: It is well documented that cardiac myxomas are associated with immunologic features that can simulate systemic autoimmune diseases. Recently, it was reported that cardiac myxomas produce IL-6 constitutively, which could partly explain the immunologic features observed in these patients. However, only a few investigators have studied cytokines in regards to symptoms they may cause in patients with cardiac myxoma. Also there is very little information in the literature on the immunohistochmical localization of IL-6. We performed immunobistochemical stains for IL-4, TNF, and IL-6 on paraffm embbeded tissue of cardiac myxoma tissue. A bioassay of IL-6 activity in patient's serum and in cultured cells from fresh myxoma tissue was performed to ascertain the role of these cytokines in myxomas. In this study, we demonstrated inununohistochemically that there was a local overproduction of IL-4, TNF, and IL-6 in cytoplasm of the tumor cells in about half cases. Bioassays of the serum and cultured tumor cells revealed elevated IL-6 activities. Also these findings correlate to production of patient's constitutional symptoms with statistical significance (P<0.05). In conclusion, these results are of considerable importance in understanding the role of IL-4, TNF, and IL-6 in cardiac myxoma patient with constitutional symptoms, and have an impact on strategies for diagnosis and therapy of cardiac myxoma.

Abstract PDF: Therapeutic management of brain tumors is based on accurate knowledge of their size, location and histologic type. Stereotaxic cytology under CT guidance has been applied to the investigation of brain tumors, especially in the sellar turcica, third ventricle, and pineal regions. In the present case, the tumor protruded into the nasal cavity, so we were able to get cytologic material via fine needle aspiration.
