Abstract
- Lipoblastomas are rare benign tumors of infancy originating from embryonic fat cells that continue to proliferate in the postnatal period. Lipoblastomas usually affect children younger than 3 years of age. Lipoblastomas may mimic other infantile tumors, including hemangiomas, lymphangiomas, lipomas, and liposarcomas. A correct diagnosis is necessary to ensure appropriate treatment. We witnessed a case of a 5-month-old boy who presented with a very firm, round, well-circumscribed mass on the posterior part of the right lower leg. On magnetic resonance imaging, a hemangioma was suspected. However, histopathological examination revealed a lobulated adipose tissue composed of a mixture of immature multivacuolated lipoblasts and mature adipocytes without nuclear atypia. Based on the clinical and histopathological findings, the diagnosis of benign lipoblastoma was made.
