Congenital lipoblastoma of the scalp

Lipoblastoma is a unique tumor of infancy and early childhood that can occur congenitally. It commonly occurs in trunk and extremities, but also rarely in head and neck. We have not encountered any report of congenital lipoblastoma of scalp in published literature. Here we describe the case of an infant who presented with a rapidly growing large scalp mass that measured 15 × 15 × 10 cm. At birth, the mass was located on the bregma but progressed to extend into the left upper eyelid and eyebrow. The mass was resected in two stages: the first stage consisted of resecting the scalp mass and the second stage consisted of excising the eyelid extension of the lesion. The histology of both resection specimens was similar and showed lobular adipose tissue separated by fibrous septae, which was consistent with a lipoblastoma. The child is free of recurrence at follow-up 3 years after the resection.
