A Case of Fibrous Xanthoma Developed in Metaphysis of Long Bone

Abstract

Fibrous Xanthoma- a rare primary bone tumor developed in the femoral metaphysis of a twenty-six years old male is described. Histologically, stromal storiform pattern, spindle shaped cells, foamy cells and giant cells are found. This feature is similar to fibrous xanthoma classified to soft tissue tumor, but it is not clear whether fibrous xanthoma of bone is different from non-ossifying fibroma or not. And it is difficut to distinguish histologically this case from malignancy, too.
