Giant omental lipoblastoma and CD56 expression

Abstract

We report a case of giant omental lipoblastoma in a 13-month-old boy, which was treated successfully by total excision. Tumor cells were positive for S100,
CD34 and CD56. This is the fi rst report of lipoblastoma expressing CD56, a fact that could be used to differentiate lipoblastoma from liposarcoma.

Key words: CD56, lipoblastoma, liposarcoma
