Abstract

Myxoinflammatory fibroblastic sarcoma and hemosiderotic fibrolipomatous tumor are rare, slow-growing soft tissue tumors of the distal extremities with recurrent potential. Recent cytogenetic studies have shown a t(1;10)(p22;q24) or der(10)t(1;10) in combination with aberrations of chromosome 3 in a limited number of cases of both entities. Here we report a case of a 42-year-old female with a soft tissue tumor of the ankle showing hybrid morphologic features of myxoinflammatory fibroblastic sarcoma and hemosiderotic fibrolipomatous tumor, a der(10)t(1;10), and abnormalities of chromosome 3. This hybrid lesion provides further evidence for a close relationship between these 2 tumor types.
