Primary cutaneous mucinous carcinoma is a rare malignant neoplasm of sweat duct origin, with the eyelid being the most common location. Secondary cutaneous mucinous carcinoma represents metastases, and it is thus imperative to differentiate primary mucinous carcinoma of the skin from metastatic lesions to the skin. Distant metastases of primary cutaneous mucinous carcinoma are rare. Surgical excision, including Mohs micrographic surgery, is recommended for treatment.
