Lipoblastomatosis: a tumor of children.

A 10-month-old boy with circumscribed lobular lipoblastomatosis of the trunk was examined and treated at the Mayo Clinic. This is only the third case of lipoblastomatosis at our institution. The diagnosis depends on the pathologist, and the lesion must be differentiated from low-grade liposarcoma. Effective treatment involves adequate local excision and local reexcision for recurrence.
