Plantar Fibromatosis


- See:
         - Fibroma
         - Desmoplastic Fibroma 
         - Soft Tissue Menu

- Discussion:
    - refers to multiple fibrous benign tumors which are locally aggressive;
    - these are more aggresive than solitary fibroma;
    - these lesions often develope in the proximal limbs or the trunk;
            - in abdomen, the tumor is called a desmoid tumors;
            - in the foot, plantar fibromatosis is common;
    - although generally superficial, tumors are locally invasive, frequently involving adjacent neurovascular structures;


- Non Operative Treatment:
    - begins w/ construction of a well molded, padded shoe & orthosis;
    - transference of weight away from prominent nodules is important;
    - may require custom-made insoles;
    - radiation therapy:
           - may be used as an adjunct to surgical excision in treatment of aggressive fibromatosis;


- Surgical:
    - indications for surgical treatment:
           - major indication for operative intervention is pain;
           - when nodules become large and painful enough to be disabling while patient is standing or walking;
    - plantar fibromatosis: operative treatment:
           - these tumors may involve neurovascular structures as well as infiltrating surrounding muscle;
           - care must be taken to place the incision away from wt-bearing region;
           - use a longitudinal medial incision  use longitudinal, s-shaped incision made on plantar surface of foot;
                  - incision can be made two centimeters posterior to head of first metatarsal, w/ extension posterolaterally, then posteromedially, & again posterolaterally,
                            finishing anterior to weight-bearing surface of calcaneus;
           - total excision of the fascia is necessary to reduce the chance of recurrence;
           - in some cases the skin will be heavily adherent to the mass, which then requires removal of a portion of the skin along with the mass;
    - resection & recurrence:
           - recurrence after incomplete excision is very common;
           - consider wider excision - even if this will require STSG;
           - use at least 2-cm  margin of normal fascia proximal and distal to nodule;
           - recurrance are difficult to distinguish from scarring of previous excisions, thus making excision even more hazardous;
           - adjuvant radiation therapy reduces that recurrence rate after marginal or even after intracapsular excision;
           - consider using of XRT as adjunct to surgical excision
