- The term malignant mesenchymoma has been applied to those tumors of the soft tissue of mesenchymal origin which are composed of tumor cells differentiating into two or more unrelated malignant forms in addition to the fibrosarcomatous element. Recently authors experienced a case of malignant mesenchymoma in the right axillary area.
Microscopically the sarcoma revealed multiple pattern of differentiation, including liposarcoma, malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma and rhabdomyoblastoma. The presence of rhabdomyblastic cells were proved by immunochemical study utilizing desmin. This patient was treated with surgical excision and radiation.

Abstract

- 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.

Abstract
PDF
- The epidermoid cyst of the testis is a rare benign lesion with a characteristic gross and microscopic appearances.
This 25 year old male who had been previously diagnosed as Klinefelter's snydrome (47/XXY) had right orchiectomy due to hard testicular nodule for a presented malignant testicular tumor. Sectioning of the testis revealed a intraparenchy matous cystic lesion, 1.5 cm in diameter, filled with cheesy white material. Histologically, stratified squamous epithelium lined the cyst. The remaining testis showed advanced tubular sclerosis and Leydig cell hyperplasia. It is necessary to submit multiple sections to rule out other histologic elements in the cyst wall or the presence of a scar. Although epidermoid cyst occurring as a solitary testicullar nodule could be regarded as a stage in the development of a teratoma, they need to be distinguished from the complex differentiated teratomas because of a distinct difference in prognosis.

Abstract
PDF
- Development of a malignant tumor within a mature cystic teratoma is a serious event, and occurs in about 1%~4% of cases. The malignant transformation occurs most frequently in the squamous epithelium with the formation of a squamous cell carcinoma. There are 10 cases reported in the literature, in Korea. We report 4 additional cases, which include 3 squamous cell carcinomas and 1 adenosquamous carcinomas, arising in cystic teratoma of the ovary.
