Calcifying aponeurotic fibroma with osseous involvement of the finger: a case report with radiologic and US findings

Soo Jung Choi et al. Korean J Radiol. 2008 Jan-Feb.

Abstract

Calcifying aponeurotic fibroma is a rare soft tissue tumor that occurs in the distal extremities of children and adolescents. We report ultrasound and X-ray findings of a calcifying aponeurotic fibroma in the finger of a 36-year-old woman, associated with distal phalangeal bone involvement.

Fig. 1
Left middle finger AP (A) and lateral (B) views show eccentrically located well-defined osteolytic lesion in the base of the distal phalanx (arrows). Calcific foci are noted in the mass and soft tissue mass component is obvious. On these radiographs, soft tissue mass with large cortical erosion is indistinguishable with eccentrically locating osteolytic mass with soft tissue extension.

A. High-resolution US demonstrates lobulated soft tissue mass (arrows) with internal punctate hyper-echoic foci (calcifications). The mass is adhered and scalloped the cortex of the phalanx (arrowheads). B. Color Doppler US shows hypo-vascularity of the mass.

Fig. 3
Histological section shows scattered calcifications (solid arrows) with surrounding chondroid differentiation (arrowheads) on the background of the fibrosis with interlacing bundles of spindle cells (open arrows) (Hematoxylin and Eosin staining, ×40).
