Plantar fibromatosis: surgical considerations with case histories

Plantar fibromatosis characteristically is found in the central and medial bands of plantar fascia, although it has been reported in other areas of the foot and, through continued growth and extension, has become adherent to tendons and overlying structures. Clinically, the lesion is somewhat uncommon, usually accompanied with minimal pain and benign in nature. However, it must be distinguished from other possibly malignant lesions that may also localize in the foot. The treatment of choice is surgical extirpation of the mass. Unfortunately, the outer limits of the lesion are difficult to define, and incomplete excision often results in return of the lesion postoperatively. Therefore, a complete fasciectomy of the involved fascia is the procedure of choice in order to reduce markedly the possibility of recurrence of the fibromatosis lesion.
