Useful techniques for the resection of foot melanomas

Surgical Management of Plantar Melanoma: A Retrospective Study in One Center

Cutaneous melanoma is a highly malignant skin tumor, and in China, the planta pedis is a commonly involved site. The sites of plantar melanomas are a challenge to reconstruct after wide excision. Our experience with surgical management of melanomas was based on the 4 different anatomic subunits of the planta pedis. From January 1, 2002 to December 31, 2016, 35 patients who had had plantar melanoma had undergone surgical treatment in our clinic. The tumor locations were as follows: the toe in 6, the ball of the foot in 5, the arch in 15, and the heel in 9. Surgical management involved extended resection of the tumor, repair of defects with skin grafts or flaps, and inguinal lymphadenectomy. The skin flaps included a residual toe flap, an anterograde or retrograde medial plantar flap, and a retrograde sural neurocutaneous vascular flap. Of the 35 cases of flaps and skin grafts, 33 (94.29%) survived, and the wounds had healed by first intention. After a follow-up period of 6 months to 7 years, 24 patients (68.57%) were free of local and systemic disease and 30 patients (85.71%) were ambulatory using shoes, and all the flaps and skin grafts showed a good appearance. The personalized surgical treatments we used for melanoma in the planta pedis resulted in overall satisfactory outcomes and adequate disease clearance, and allowed the patients to resume normal lives. The function of the foot was maintained or restored to the greatest possible degree, and the patients' quality of life improved postoperatively.
