Two young girls with lipoblastoma and a review of the literature.

Lipoblastoma is an uncommon, benign tumor of embryonic adipose tissue that occurs predominantly in the pediatric population. It most often presents on the extremities. Biopsy of the lesion is standard for diagnosis, as clinical and radiologic diagnoses can be misleading. A complete yet conservative surgical excision is the preferred treatment modality. We describe two young girls with lipoblastoma and review the dermatologic literature. Initial biopsy of the lesion in these two patients was not diagnostic. Both tumors were excised and subsequent gross and histopathologic examination demonstrated features of lipoblastoma.
