ABSTRACT
Microcystic adenxal carcinoma is an unusual, locally aggressive neoplasm that has recently been recongized as a clincopathologic entity. Its histologic appearance includes both pilar and eccrine differentiation. Microscopically, the tumor consisted of small cysts and gland-like structures in superficial portion. In other area, basaloid cell nests and abortive hair follicles in the sclerotic stroma were seen. The cysts were filled with secretory eosinophilic material, which was positively stained with Periodic acid-Schiff and carcinoembryonic antigen. Immuno-peroxidase staining for carcinoembryonic antigen supported the dual differnetiation of this neoplasm. Despite the benign histologic appearance, there was deep and extensive infiltration of the subcutaneous tissue.

A primary skin adenoid cystic carcinoma first described by Boggio in 1975, is one of the rarest type of eccrine sweat gland carcinoma. Histologically, a tumor with typical morphologic features closely resembles adenoid cystic carcinoma was found in other tissues but in the skin must be distinguished from aggressive basal cell carcinoma. The natural history of this tumor is not yet fully determined but suggests a long indolent and progressive course. We report a case of a 77-year-old male with a small skin nodule in the abdomen.

Malignant mixed mullerian tumor of the fallopian tube is an extremely rare neoplasm. To date, only 26 cases of primary malignant mixed mullerian tumor of the fallopian tube have been reported, and no report has been published in Korea. This is not surprising, since as a group these meoplasms are least likely to occur in the fallopian tube; the most common sites being the endometrium, vagina, cervix and ovary. We report a case of malignant mixed mullerian tumor of the fallopian tube ina 63-year-old woman with brief review of the literatures.

Malignant acanthosis nigricans is very rare disease. The disease is related with internal malignancy, especially gastrointestinal tract malignancy. Reported occurrence rate of malignant acanthosis nigricans associated internal malignancies are 64% of stomach adenocarcinoma, 27% of other organs of abdomen (liver, gall bladder, small intestine, rectum, uterus, ovary), 9% of non-abdominal organs(breast, lung). We report a case of malignant acanthosis nigricans associated with stomach adenocarcinoma from 20-year-old female and discuss review of literature on a acanthosis nigricans briefly.
