Benign lipoblastomatosis is a tumor consisting of fetal-embryonaladipocytes, frequently confused with a liposarcoma, affecting exclusively infants and young children, with approximately 90% of cases occurring before 3 years of age.: 626 The term lipoblastomatosis was first used by Vellios et al. in 1958, at which point the tumor became generally accepted as a distinctive entity. Today Diffuse lipoblastoma is the preferred term for Lipoblastomatosis. The tumor is rare, accounting for less than 1% of all childhood neoplasm, and it has been found to be more common in males than females. It often presents as an asymptomatic rapidly enlarging mass, occurring more often in the soft tissues of the extremities.
