Mature benign lipoblastoma: A rare case

Abstract

We report here a case of lipoblastoma in a 14 year old boy along with a brief review of literature. He presented with multiple soft tissue swellings averaging 1 to 2 cm in maximum dimension over his right thigh and upper limbs with no other apparent constitutional symptoms. These were present since 2 years and were slowly enlarging. Ultrasonography revealed lipoid like density of these masses. Excision of one of his thigh swellings was carried out and histopathological examination revealed presence of lipoblasts in a myxoid background, which was unusual at this age of presentation. The final diagnosis was made as mature benign lipobastoma. Myxoid liposarcoma was considered as a differential diagnosis, however, it was ruled out on account of absence of any nuclear atypia or pleomorphism. Patient was subsequently discharged with no evidence of recurrence at the excision site even at one year of follow up.
