Microcystic Adnexal Carcinoma: Report of a case.: Eun Deok Chang, Young Hee Jee, Sun Moo Kim; Korean J Pathol. 1993;27(3):290-292.

Abstract PDF: 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.

Abstract PDF: A clinico-pathological study on the true skin appendage tumors was carried on the accumulated cases during pat 11 years from 1976 to 1986 years in the Department of Pathology, Seoul National University Hospital. The results was as follows; 1) Among various benign skin appendage tumors pilomatricoma was the most common benign tumor consisting of 72 out of 244 cases (30.1%), followed by dermoid cyst 48 cases (20.0%), steatocystoma multiplex 37 cases (15.5%), syringoma 33 cases (13.8%) and trichilemmal cyst 19 cases (0.8%). Other benign skin appendage tumors were rarely noted under 3%. Sebaceous carcinoma was most common among malignant skin appendage tumors and no malignant tumor of sweat gland origin was noted. 2) The sex ratio of male to female of the pilomatricoma was 1 : 2.6 and on the face, neck, and extremeties in 1st and 2nd decades. The sex ratio of dermoid cyst was 1 : 1.2 on the face in 1st decade. The sex ratio of steatocystoma multiplex was 1 : 1.9 and on the trunk in 3rd decade. The sex ratio of syringoma was 1 : 7 and on the face in 5th decade. The sex ratio of trichilemmoma was 1 : 1.6 and on the trunk in 5th decade. Other tumors were not avaiable for analysis because of small number. The sex ratio of sebaceous carcinoma was 1 : 2 and on the eyelid in 6th decade
