[Metastatic Basal cell carcinoma in the axilla: reconstruction with a lateral pectoral island flap]

Although basal cell carcinoma (BCC) is one of the most common forms of cancer worldwide, it rarely occurs in the axilla. Only 31 cases have been reported in the literature. The incidence of metastatic BCC, particularly in areas not exposed to the sun, is very low. We present a new case of axillary BCC with lymph node metastases and the results of an extensive review of cases previously reported in the literature. BCC in the axilla is rare and metastasis is exceptional. Factors other than UV radiation probably contribute to its development. The lateral pectoral island flap was used for surgical closure. This method is useful for the reconstruction of axillary defects, obtaining excellent cosmetic and functional results. This flap should therefore be considered for the repair of large surgical defects in the axilla.
