A plantar fibroma is a benign nodule that grows on the bottom of the foot that usually appears in the second through sixth decade of life. It is usually slow growing and measures less than an inch in size. More invasive, rapidly growing (aggressive), and multiplanar fibromas are considered plantar fibromatosis. Both of them are benign tumors made up of cells, or fibrocytes, found in ligaments.
Asymptomatic fibromas may be observed. Symptomatic (painful) fibromas may be treated with an off-loading insole or pad. Surgery is done for symptomatic fibromas when conservative treatment fails to give adequate pain relief. The recurrence rate is low for fibromas and significantly higher for plantar fibromatosis and in revision cases. Risks of surgery include wound complications, injury to local structures such as the digital nerves, and recurrence.
Recovery may be hastened by elevation of the foot and diligent control of swelling to help prevent hematoma (blood clot) formation and delayed wound healing. Return to unrestricted activity and shoewear is in the one to two month range.
Recurrence is rare for fibromas but more common in multiple lesions or if invasive lesions are encountered.
- Wound drainage or infection
- Healed but painful wound
- Recurrent mass
- Chronic neuritic pain, especially for an invasive lesion or in revision surgery
