Soft-tissue tumors

Superficial CD34-positive fibroblastic tumor

Soft tissueIntermediate / locally aggressive or rarely metastasizingFibroblastic / myofibroblastic tumours

Epidemiology

A rare superficial neoplasm of adults, described mainly in the limbs and subcutaneous tissue. The microscopic appearance can seem alarming, so review by expert pathology avoids overtreatment.

Basic features

It can show striking atypia under the microscope despite a relatively indolent clinical course.

Usual treatment

It is managed with complete removal and expert pathology review to distinguish it from more aggressive sarcomas.

Outcomes and prognosis

Recurrence and metastasis are uncommon, but follow-up is advised because of its rarity.

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.
