Giant lymph node hyperplasia (Castleman's disease) was first described by Castleman and associates. In the first accounts of giant lymph node hyperplasia, the lesions were described as solitary and localized to the mediastinum. Recently, we have experienced three cases of Castleman's disease, first of which is a 54 year old male with plasma cell type in the mesentery, second is 27 year old femal with hyaline vascular type in the inguinal region and third is a 29 year old female with hyaline vascular tye in neck.

Meningeal carcinomatosis as the initial clinical manifestation of a tumor is a very rare event and difficult to make diagnosis. Lumbar puncture is a single and useful diagnostic method, and meticulous cytologic study of cerebrospinal fluid specimen is needed for correct diagnosis. A case of meningeal carcinomatosis diagnosed by cytologic study of CSF and later confirmed primary carcinoma of the stomach by, fiberscopic biopsy is briefly presented. Meningeal signs and symptoms were the primary clinical manifestation in case.

Cancer of the alimentary tract in children is an extremely rare occurence, and it accounts for no more than 5% of all pediatric neoplasms. Malignant neoplasms of the stomach are particularly uncommon in childhood. The majority of such lesions are malignant lymphomas or soft tissue sarcomas, with less than 5% identified as carcinomas. We report a case of signet ring cell carcinoma of stomach in 15-year-old girl. This patient had a clinical manifestation of cough with sputum, fever, abdominal distension due to ascites, hepatomegaly, and cervical lymphadenopathy for 40 days. There was no known gastrointestinal symptoms. Metastatic signet ring cell carcinoma was suspected by aspiration biopsy cytology of cervical lymph node, and confirmed later by excisional biopsy. Endoscopy confirmed a small mucosal erosion in the anterior wall of the antrum and histopathology confirmed the diagnosis of signet ring cell carcinoma.

Estrogen receptor(ER) is a soluble form of hormone receptor protein which is located in the nucleus and cytoplasm of a cell is found in 60% of cases of the cells of breast carcinoma. Fifty to sixty percent of ER positive breast carcinoma responds to antihormone therapy wheres the response rate is only 5% in ER negative tumors. Currently, the ER assay has become a standard index in the management and prediction of the prognosis of advanced breast carcinoma. Semiquantitative biochemical assay, dextran-coated charcol(DCC) assay, to measure ER from fresh tissue was first developed by Korenman in 1970 using isotope-labled ertradiol, has been widely utilized. In 1978, Kurzon newly developed immunocytochemical assay(ICA) employing monoclonal antibody against those hormone receptors to detect intracellular localization of ER and progesterone receptor (PR). The results of the assay have been reported by many investigators thereafter. The purpose of this study was to evaluate the hormonal receptors with a monoclonal antibody using an immunoperoxidase procedure to detect both estrogen and progesterone receptors (ER-immunocytochemical assay:ER-ICA and PR-immunocytochemical assay:PR-ICA) in 59 cases of paraffin embedded sections from formalin-fixed and routinely processed breast carcinoma tissue. Concomitantly, fine-needle aspiration biopsy cytology of the breast cancer from 29 women were assayed for ER/PR receptors. Results were compared with quantitative biochemical values determined from dextran-coated charcoal(DCC) assay on the fresh tumor tissue obtained subsequently from the surgery. ER-ICA showed positive result in 22 out of 36 DCC-positive cases(sensitivity, 61.1%) and negative in 23 out of 23 DCC-negative cases (specificity, 100.0%). PR-ICA was positive in 33 out of 35 DCC-positive cases(sensitivity, 94.3%) and negative in 16 out of 24 DCC-negative cases(specificity, 66.7%). The value of ER-ICA or PR-ICA positivity were roughly correlated with the concentration of ER/PR receptors analyzed by DCC method. The results of both methods were correlated with the nuclear grade of the tumor(ICA:p=0.002, DCC: p=0.015) but were not correlated with histologic grade(ICA: p=0.323, DCC: p=0.0164). ER-ICA positivity was correlated with lower incidence of axillary node metastasis (p=0.021) but no significant correlation between PR-ICA positivity and node metastasis(p=0.171). Both ER/PR-ICA positivity were not correlated with age(p=0.924) and tumor size(p=0.663). The score of ICA particularly ER was proportional to DCC level(ER: r=0.5, p=0.000, PR: r=0.2, p=0.000). ICA concordance with DCC of ER and PR were 76.3% and 83.1%, respectively. The concordance of PR-ICA and DCC was proportional but was statistically less significant. In aspiration biopsy cytology the concordance of ER/PR-ICA and DCC were 72.4% and 65.5%, respectively. Immunocytochemical staining to identify ER/PR receptors from the tissue of breast carcinoma would be tested as a mean to substitute for the conventional DCC method.

A case of extrastkeletal Ewing's sarcoma on lower extremity in a 60-year-old male is reported. Extraskeletal Ewing's sarcoma is a rare malignant neoplasm that shows similar histologic and ultrastructural features to Ewing's sarcoma of bone. Histologically, the neoplasm was composed of small, round to oval cells with scant cytoplasm that were arranged in sheets with large area of necrosis. Electron microscopy of the neoplastic cells revaled scant cytopasm containing glycogen rosettes and a paucity of organelles. There is no ultrastructural evidence to indicate the origin of the cells.

Sebaceous carcinoma is uncommon and usually presents in the ocular adnexa as a cancer of the meibomian glands. They are frequently mistaken for chalazion. Considerable time often elapses before a diagnosis is made. We present a case of sebaceous carcinoma of the left eye lid in 59 year old female who had a history of 3 repeated surgical resections clinically diagnosed as chalazion during last 3 years.

A histopathologic study including iramunohistochemical stains was made in 30 patients who were presented with gastrointestinal lymphoma. The occurrence was 13 in the stomach, 8 in the ileocecum, 7 in the small intestine and 2 in the colon. The disease more frequently affected males than females and the average ages were 53 years in the patients of gastric lymphoma and 44 years in the patients of intestinal lymphoma. Gastric lymphomas were usually presented with a single lesion, and the antrum and/or body were the most common sites. But intestinal lymphomas were presented with a single or multiple lesion, and the ileocecum was the most common site. The most common gross type of gastrointestinal lymphomas was the ulceroinfiltrating type and most are of the diffuse large noncleaved cell type of B-cell lymphoma, histologically. There were 2 cases of T-cell lymphoma presented in the intestine as the superficially ulcerative gross pattern and diffuse immunoblastic cell type. The distinct MALToma was seen in only one case of stomach but the feature was partially remained in each two cases of stomach and intestine. Their coexistent findings may suggest that diffuse large of immunoblastic component arises through blastic transformation of the low-grade M ALToma component.

Primary hepatic carcinoid tumors are extremely rare although the liver is a frequent site of metastases from intestinal carcinoids. Recently we investigated a case of primary hepatic atypical carcinoid in a 47-year-old man who had infested with Clonorchis sinensis for 20 years. The resected right lobe of the liver was almost completely occupied by a huge tumor, measuring 20 x 19 x 12 cm. The cut surfaces of the mass were solid, soft and pale yellow, accompanied by several small satellite nodules, measuring up to 1.5 cm in diameter. Microscopically, the tumor consisted of polygonal to columnar cells with eosinophilic granular cytoplasm forming Lym-numerous small acini and large trabeculae. Their nuclei were round to polygonal with coarse stone chromatin, had obscure to small nucleoli and frequent mitoses. There were multiple necrotic foci of varing sizes. The surrounding dilated bile ducts contained several degenerating worms on in of Clonorchis sinensis. The tumor cells were argyrophil-positive but argentaffin-negative. Immunohistochemically, the tumor cells were positive for cytokeratin, chromogranin and somatostatin but were negative for CEA, AFP, insulin, glucagon, ACTH, growth hormone and volve-prolactin. Ultrastructually, the tumor cells contained variable-sized numerous electron dense of neurosecretory granules.

Historically, gastrointestinal stroma tumors (GIST) have been considered as smooth muscle tumors, but the controversy over this histogenesis is provoked due to various results with utilizing immunohistochemical methods. In andeffort to further clarify the histogenesis of GIST, we performed the immunohistochemical study, as well as histopathologic reexamination, of 24 cases, all diagnosed as smooth muscle tumors of gastrointestinal tract, from Seoul Paik Hospital and Ewha University Hospital between 1980 and 1989, and the main results were as follows; 1) In the histopathologic features by light microscopic study, 11 benign and 13 malignant lesions (including one high grade malignancy and 12 low-grade malignant lesions) were disclosed. 2) In the immunohistochemical study, all tumors showed Vimentin positivity (100%), but no tumor showed S-100 protein positivity (0%), and 7 cases (29.1%) showed Desmin positivity. Positive reaction for Desmin made it possible to suggest that the histogenesis of GIST be in smooth muscle, and neurogenic origin would be excluded by all negativity for S-100 protein. In summary, we would like to conclude that GIST would be smooth muscle tumors on account of their morphological characteristics and their intramural location, but most of them appear poorly differentiated by immunohistochemical method.

Although the mediastinum is the second favorite location of primary teratoma in adults, primary malignant teratoma in mediastinum is rare in incidence. Malignant teratoma includes teratocarcinoma, immature teratoma and malignant transformation in benign teratoma. The latter is rarer than others types, and undifferentiated or squamous cell carcinoma are the major incidence. We experience a case of unique adenocarcinoma composed of signet ring cells in mature teratoma of mediastinum and brief review of the literatures are included.
