Primary Cutaneous Mucinous Carcinoma Treated with Micrographic Surgery

Primary mucinous carcinoma of the skin (PMCS) is a rare, slow growing tumor with a high recurrence rate and occasional metastasis. It most commonly presents as an asymptomatic nodule on the face, particularly the eyelids. PMCS is resistant to radiation and chemotherapy. Historically, a wide local excision has been the treatment of choice, but it has high recurrence rates. While no current definitive treatment guidelines are available, limited data suggests that Mohs micrographic surgery (MMS) may result in significantly lower recurrence rates than excision. We report a case of recurrent PMCS treated with MMS.
