Basal Cell Carcinoma of the 2nd Digit Treated With the Reverse Cross-Finger Flap: A Case Report

Basal cell carcinoma (BCC) is the most common form of skin cancer but rarely presents on the finger with few cases described in the literature. We present the case of a 77-year-old female with a nine-month history of biopsy-proven BCC on the dorsal aspect of her left index finger. Following the complete surgical excision of the tumor, a two-stage reverse cross-finger flap was performed, resulting in minimal impact on mobility and aesthetics and prompting a discussion on the efficacy of this approach in treating BCC of the hand. We explore the various treatment modalities available for BCCs, underscoring the importance of tailored interventions for optimal patient outcomes. The successful outcome in our case emphasizes the significance of considering alternative surgical techniques in managing uncommon presentations of BCCs, contributing to the evolving armamentarium of options available to hand surgeons.
