Plantar fibromatosis is a benign proliferative neoplasia of the plantar fascia.

Corticosteroid injections directly into the nodule may be tried (see Considerations for Using Corticosteroid Injections Considerations for Using Corticosteroid Injections Most foot problems result from anatomic disorders or abnormal function of articular or extra-articular structures (see figure ). Less commonly, foot problems reflect a systemic disorder (see... read more ).

Surgery usually results in recurrence and sometimes painful scar tissue necessitating further surgery. Excessive fascial removal may also result in unintentional instability of the foot and the loss of arch height.
