Primary mucinous carcinoma of the skin. Report of case.

The authors report a case of a primary mucinous carcinoma of the skin. This is a rare adnexial tumor arising from the eccrine secretory coils. The histologic characteristic finding of this lesion is the heap of abundant mucinous material (sialomucin) in the dermis in which rare epithelial islands are free-floating. In this study we also value the importance of a correct diagnosis for an appropriate therapy.
