Ulcerated Basal Cell Carcinoma. These lesions are moist ulcers which may not have the characteristic rolled, translucent border of a nodular basal cell carcinoma. They can be much larger than the pre-auricular lesion seen here, and represent neglected lesions. pre-auricular basal cell carcinomas are more likely to recur after treatment. Therefore Mohs surgery surgery is recommended to lessen the likelihood of recurrence.
