Abstract

Proliferative fasciitis (PF) of the hand is a rare condition, which typically occurs in adulthood. To date, only two dozen cases of PF have been reported in children. This benign condition can mimic malignant soft tissue tumors such as soft tissue sarcoma. We present a case of histopathologically confirmed PF of the fifth right finger in a nine-year-old girl, along with the imaging workup. We also provide a review of the previous literature on PF in children.

Summary

Introduction

Proliferative fasciitis (PF) is a benign pseudosarcomatous myofibroblastic proliferation of the soft tissues [1]. Ultrasound (US), and MRI findings correlated with histopathological specimens in this case report on a nine-year-old girl with PF of the right hand. Ultrasound revealed a 22-mm oval mass located in the palmar aspect of the fifth MCP joint, contiguous to the fifth flexor tendons and surrounded by diffuse soft tissue edema. A) radiograph demonstrating periosteal reaction (white arrow) in the ulnar aspect of the proximal phalanx of the fifth finger; B) ultrasound B-mode imaging shows a central echogenic region, with a hypoechoic rim; C) Doppler interrogation demonstrates minimal vascularity associated with the hypoechoic region, as well as surrounding hyperemia. A) coronal T1-weighted demonstrates a mass which is homogeneously isointense to muscle (white arrow); B) axial T2-weighted FS demonstrates heterogeneous signal, hyper-intense in the periphery (black arrow); C) contrast-enhanced axial T1-weighted FS image demonstrates rim-like enhancement (curved discontinuous arrow), as well as enhancement of some central foci.
