ABSTRACT
Primary cutaneous mucinous carcinoma is a rare malignant tumor that originates from the deepest portion of the eccrine sweat duct. Common sites of involvement are the face and scalp. Biopsy shows dermal epithelial cell islands embedded in mucin pools separated by fibrous septae. It is difficult to differentiate this tumor histologically from metastatic adenocarcinoma. Recurrence after excision is common but metastases are rare. We report a primary cutaneous mucinous carcinoma with neuroendocrine differentiation on the right cheek of a 63-year-old man.

Primary mucinous carcinoma is a rare malignant tumor that arises from the deepest portion of the eccrine duct. This tumor consists of large mucinous pool with fibrous septae and clusters of tumor cells. Immunohistochemical staining was studied for the differentiation, but has only limited value. We present a case of mucinous eccrine carcinoma in 56-year-old man and review the literature.
