Abstract
- Lipoblastoma is a rare benign mesenchymal tumor that exhibits a tendency to invade locally but not to metastasize, and develops from embryonic remnants of white fat tissue. We experienced a case of lipoblastoma occurring in a 7-month-old girl. A small nodule developed on her right inguinal region at the age of 4 months. It had grown to be a 1.2x2.0cm in size, well-defined, volcano-like, ovoid erythematous nodule. Histopathologically it was composed of well-defined lobulated fat tissue with multivacuolated lipoblasts, undifferentiated mesenchymal cells such as stellate or spindle cells and minimal myxoid stroma. Electron microscopic findings demonstrated lipoblasts with eccentric nuclei and coarse chromatins. Complete local excision was done.
