A Case for a Local Flap as Primary Reconstruction for Hidradenocarcinoma of the Leg.

Hidradenocarcinomas are rare, aggressive sweat gland tumors typically occurring in the scalp and upper extremities. They have rarely been described in the lower extremity. Due to their rarity, there is little consensus on optimal adjuvant therapy for these tumors after resection. Regardless, it is important to plan tumor excision and subsequent reconstruction with adjuvant therapy in mind. This case report describes a patient for whom a local muscle flap with skin graft provided adequate wound coverage after excision of hidradenocarcinoma and negative-pressure wound therapy. The surgical site then withstood adjuvant radiation therapy. When radiation is planned to a wound bed after tumor excision, a local muscle flap is the excellent first choice over skin graft alone regardless of wound bed characteristics.
