ABSTRACT

Objective:

Basal cell carcinomas (BCC) are the most common cutaneous malignancy and most often seen in the head and neck region, only 1.2% occur in unusual localizations. We aimed to analyze the incidence and clinicopathologic features of our unusual localizations between 2006-2016 in our study.

Methods:

BCC findings in excisional biopsies from 2006 to 2016 were rewieved retrospectively.

Results:

Of 1140 patients with BCC diagnosis, only 11 (2 vulva, 2 inguinal region, 2 umbilicus, 1 acral-periungual region, 1 anal region, 1 areola, 1 sacral region and 1 axilla) were unusual localized. Lesions at a unusual localization accounted for 0.96% (11 cases) of all cases. Nodular, superficial and cystic variants were observed in these cases.

Conclusion:

BCC should be considered in unusual localizations due to its local aggression and tissue destruction however the risk of metastasis is very low.
