Pigmented basal cell carcinoma over trunk: An unusual location

Abstract

Basal cell carcinoma, also known as “ulcus rodens”, was first described by Jacob in 1827. It is the most frequent type of skin cancer, accounting for approximately 80% of all non-melanoma skin cancers. No precursor lesions have been described for BCC. In 80-85% of the cases, BCC commonly develops over head and neck. Rarely, basal cell carcinoma has been reported over unusual locations such as axilla, groins, umbilicus, trunk, palm and soles. Only ten percent of tumors are seen over trunk. We report a case of pigmented basal cell carcinoma in a 22-year-old female located on trunk, highlighting its dermoscopic, histopathological and immunohistochemistry findings.
