Abstract

Proliferative fasciitis is a rare reactive condition that presents with pseudosarcomatous lesions in subcutaneous tissues. Clinically, most patients present with firm, rapidly growing subcutaneous nodule and two thirds of patients complained of pain and tenderness. Most of lesions occur in the extremities, with the upper extremity (especially the forearm) affected more commonly than the lower extremity. Microscopically, proliferative fasciitis is composed of spindle cells that are deposited in a variably myxoid and collagenous stroma. It is characterized by the presence of large basophilic cells with one or two vesicular nuclei. Proliferative fasciitis could be confused with sarcomas because of intense cellularity, high mitotic index, and rapid growth. A 26-year-old woman complained of a painful nodule on her right second finger. Its size was gradually increased and pain was worsened. Histopathological examination revealed that the lesion consisted predominantly of spindle-shaped cells intermingled with a few gangliocyte-like giant cells. We herein report a rare case of proliferative fasciitis in the finger in a 26-year-old woman.
