Soft-tissue tumors

Palmar / plantar fibromatosis

Soft tissueIntermediate / locally aggressive or rarely metastasizingFibroblastic / myofibroblastic tumours

Epidemiology

A fibroblastic lesion of the palmar or plantar fascia, more common in adults. The functional impact is measured by contracture, pain on weight-bearing, or difficulty using the hand, not only by the nodule.

Basic features

It forms nodules or cords that can cause plantar (sole) pain or a contracture in the hand.

Usual treatment

Treatment begins with conservative measures. In Dupuytren's disease (hand), needle aponeurotomy (and, where available, collagenase injection) can be used before open surgery; radiotherapy is reserved for selected early stages, and surgery for a contracture or pain that does not improve.

Outcomes and prognosis

Recurrence after surgery is common, so treatment must be indicated according to the real impact on function; it does not metastasize.

Warning signs

These signs do not necessarily mean cancer, but they warrant evaluation before operating on or needling a mass.

  • A soft-tissue mass that grows, is larger than 5 cm, or is deep.
  • Persistent, night-time or progressive bone pain, especially if it limits activity.
  • A fracture from minimal trauma, or an aggressive bone lesion on an X-ray.
  • A lump that comes back after previous surgery.
  • Neurological symptoms, rapid swelling, or pain associated with a mass.

This information is general and does not replace a medical evaluation. A musculoskeletal tumor must be interpreted together with imaging, physical examination, biopsy when appropriate and each patient's context.

Specialist evaluation

If you have a mass, a bone lesion or a report suggesting a tumor, book an evaluation.
