Abstract:
Calcifying fibrous pseudotumor is an uncommon tumor first described in 1988 as a childhood fibrous tumor with psammoma bodies. The typical pathological findings are those of a densely collagenized fibrous tumor with psammomatous and dystrophic calcification accompanied by a lymphoplasmacytic infiltrate. To date these tumors are reported in subcutaneous and deep soft tissues of the extremities and trunk, groin, scrotum, pleura, mediastinum, paratracheal region, peritoneum, neck, mesentery, omentum, serosa, lung, bone, and gallbladder. We describe a 17-year-old girl with a myocardial calcifying fibrous tumor, and we review the English literature.
