Basal cell carcinomas (BCC) arise from DNA damage to cells of the basal layer of the epidermis and most commonly in areas of the skin exposed to sunlight or ultraviolet radiation. BCC is the most common skin cancer seen in humans with over 4.3 million cases reported in the United States and is responsible for 3-10% of all cancers annually. We report what we believe to be the first case of this very prevalent skin cancer arising in the nasal vestibule. The lesion was treated with Mohs micrographic surgery and required three stages to obtain histological clearance. Given the location of the tumor, Mohs surgery was chosen due to the procedure’s effectiveness for achieving the highest cure rate with the lowest incidence of tumor recurrence and for preserving as much adjacent healthy tissue as possible

Standard of care for squamous cell carcinoma (SCC) is usually surgical, with either excision or Mohs micrographic surgery. However, surgery may not be ideal for elderly patients with numerous lesions, who are poor surgical candidates or who refuse surgery. Topical 5-fluorouracil (5-FU) and imiquimod have been studied off-label as monotherapies in the treatment of SCC in situ with promising results. However, long-term tumor-free survival rates are still less than with surgical management.
