Two rapidly growing fatty tumors of the upper limb in children: lipoblastoma and infiltrating lipoma.

Abstract

One case of lipoblastoma and another case of infiltrating lipoma of the upper limb in infancy are reported. These rare benign fatty tumors may be congenital and may grow rapidly soon after birth. The classification of these fatty tumors and their management are presented to increase awareness of the benign nature of these tumors despite their rapid growth and to demonstrate that complete surgical excision should be done to prevent local recurrence.
