 Abstract

- Cytologic features of the fine needle aspiration of metastatic epithelioid sarcoma are presente. The patient was a 48 year-old male who had been sufferring from recurrent and metastatic tumors of the right upper extremity for 6 years. The aspirate from the axillary mass cytologically consisted of isolated large polygonal cells with abundant, cyanophilic, slightly granular cytoplasm. Eccentrically located large round nuclei showed finely dispersed chromatin, small nucleoli, occasional convolution and folding of nuclear membrane, and frequent binucleation.
Although both histologic and cytologic similarity of epithelioid sarcoma to squamous cell carcinoma is well known, findings of cyanophilic granular cytoplasm, convoluted nuclei, and binucleation appeared to be the differential points.

Abstract

- We report a case of malignant tumor of the stomach showing both carcinoma and sarcoma components in a 47 year-old woman. The resected stomach revealed two tumors which were in different location. The one mass was a 2 x I cm, poorly demarcated tumor at the body, along the lesser curvature and the other was a 6 x 7 cm, well demarcated polypoid tumor with a central depression at cardia of the posterior stomach wall. The tumor at the body was a poorly differentiated adenocarcinoma which showed strong reactivity for CEA. The tumor at the cardia was composed of epithelioid or spindle shaped cells with abundant eosinophilic cytoplasm and revealed 5-6 mitoses per ten high power field. The tumor at the cardia was diagnosed as epithelioid leiomyosarcoma and showed reactivity for vimentin but none for actin, desmin,keratin, and CEA. This is different from the usual carcinosarcoma.

Abstract
- Malignant glomus tumor is a rare neoplasm arising from the glomus body, comprising categories of locally infiltrative glomus tumor, sarcoma arising in benign glomus tumor and de novo glomangiosarcoma. We report one case of locally infiltrative glomus tumor arising in nail bed of the right thumb of a 50 year-old woman. The tumor showed the architectural features of glomus tumor but cytologically bizarre, pleomorphic features without mitosis and infiltrative growth pattern to adjacent connective tissue and nerve. Immunohistochemical results were consistent with glomus tumor. This category of malignant glomus tumor must be distinguished from other round cell tumors because of its good prognosis.
