Plantar Verrucous Carcinoma. Report of a rare case

Abstract

Background: Verrucous carcinomas rarely mentioned in the literature its location on the soles of feet, being a distinct variant of squamous cell carcinoma seen in mucosa and skin, including the feet. Objective: To describe the clinical, histopathological and laboratory and clinical results of an unusual case of a verrucous carcinoma on the sole.

Methods: We present a rare case of a verrucous carcinoma in the left sole, at the first metatarsal, which was completely resected and remained without evidence of tumor recurrence or metastasis during follow-up over a period of four years. On this basis, we reviewed the published cases of verrucous carcinoma in the foot, to define the characteristics of this rare tumor and give diagnostic and therapeutic recommendations.

Results: Verrucous carcinoma is characterized by a slow but inexorable clinical presentation similar in appearance to large plantar wart, histology is typical minimal local invasion with low incidence of metastases and good prognosis. For the correct diagnosis, both physical examination and must be comprehensive and complementary performed by surgical biopsy. Radical resection is the treatment of choice with histological confirmation of free resection margins of the tumor.

Conclusions: The plantar verrucous carcinoma may present diagnostic difficulty, complete surgical resection of the lesion allows the diagnosis, prognosis and has good early healing.
