Primary Cutaneous Mucinous Carcinoma

**Semantic type:** Neoplastic Process

**Definition:** A rare low-grade carcinoma of the sweat glands. The most common sites are eyelids, scalp, axilla, face and trunk. It is histologically characterized by proliferating ducts until the overproduction of mucin creates islands of tumor cells, essentially floating in mucinous pools (Rosai J. Ackerman's Surgical Pathology).

**Synonyms:** - Adnexal Mucinous Adenocarcinoma - Adnexal Mucinous Carcinoma - Sweat Gland Mucinous Carcinoma
