Calcifying aponeurotic fibroma is a relatively rare, benign soft tissue tumor that is one of the superficial fibromas and typically occurs in the distal extremities of children and adolescents. We report a case of calcifying aponeurotic fibroma developing in the lower back region, which is a fairly uncommon site. This is the first reported case of a multiple calcifying aponeurotic fibroma occurring in the back. Histologically, poorly marginated proliferation of fibroblasts and cartilage formation accompanied by central calcification were characteristic features.
Calcifying aponeurotic fibroma is an ill-defined mass and has a tendency to infiltrate into the surrounding tissues. Because of its high local recurrence rate (50%), an appropriate excision is required and long-term postoperative follow-up is recommended.
