Primary Cutaneous Mucinous Carcinoma of the Nasal Bridge

Mucinous carcinoma is a rare appendage tumor that is resistant to surgery, chemotherapy, and radiotherapy.  It has an unremarkable appearance and must be distinguished as a primary tumor or as a metastasis from distant sites.  Detailed imaging studies and immunohistochemical investigation are often essential.  Here, we report a case of surgery-refractory primary mucinous carcinoma on the left nasal bridge in a 62-year-old female that ultimately required removal by Mohs surgery.
