Proliferative Fasciitis : Intro & Clinical
Introduction: Proliferative fasciitis is a benign, reactive, pseudosarcomatous lesion that is related to nodular fasciitis. It is characterized by proliferation of ganglion-like myofibroblasts in the subcutaneous tissue. It is often misdiagnosed as embryonal rhabdomyosarcoma, ganglioneuroblastoma, or other sarcomatous processes. Clinical Features: The most commonly affected age group is 40 to 70 years (mean 54 years) with no sex or race predilection. It is uncommon in children.. The most common site is subcutaneous tissues of upper extremity followed by lower extremity and trunk. The usual presentation is with a small (median size 2.5 cm), firm, freely mobile subcutaneous nodule that may be accompanied by pain or tenderness. The lesion shows rapid growth and there is history of trauma in about one-third of cases. This low power scan shows an irregular, poorly-circumscribed mass in the subcutaneous tissues.
