In a case of isolated plantar fibromatosis, the lesion has recurred twice, even though postoperative radiotherapy was utilized once. Because of its locally aggressive nature and its tendency for ulceration and recurrence, plantar fibromatosis has often been mistaken for a malignant process. Complete local excision with removal of the entire plantar fascia seems to be the best treatment. Close follow-up and observation for any sign of recurrence is essential.
