Sclerosing epithelioid fibrosarcoma with der(10)t(10;17)(p11;q11)

Abstract

Sclerosing epithelioid fibrosarcoma is a recently described, rare mesenchymal neoplasm. We report a case of sclerosing epithelioid fibrosarcoma that occurred in the lower leg of a 48-year-old man. The karyotype of the tumor exhibited der(1)t(1;10)(p31;p11), der(10)t(10;17)(p11;q11), and der(17) t(11;17)(?;q11). Rearrangement of 10p11 was also found in one previous reported case of this uncommon tumor.
