Abstract
- Lipoblastoma is a rare, benign tumor arising from embryonic fat tissues that continue to proliferate in the postnatal period. So, lipoblastoma occurs almost exclusively in infants and children younger than 3 years of age. Published reports showed that 70~90% of cases occur before the age of 3. Histopathologically, lipoblastoma, mimicking liposarcoma, was composed of well-defined lobulated fat tissue with multilobulated lipoblasts, undifferentiated mesenchymal cells, such as stellate or spindle cells and minimal myxoid stromas. The diagnosis of lipoblastoma is important because its management differs from that of lipoma and liposarcoma. To our knowledge, there are only a few reports of lipoblastoma in the Korean dermatologic literature. Herein, we present an interesting and atypical case of lipoblastoma in 68-year-old woman.
