Lipomatous tumors in pediatric patients are rather rare and a recent histopathological study on lipomatous tumors in 50 pediatric patients in a single institution showed 26 cases of lipoma (52%), 19 cases of lipoblastoma (38%), 3 cases of liposarcoma (6%), and 2 cases of ALT (4%) [26]. This evidence concerns the gene GPT and liposarcoma.
