Epidermal nevus and rhabdomyosarcoma.

A child with an epidermal nevus was diagnosed at the age of 15 months as having an embryonal rhabdomyosarcoma of the bladder. This child also had pigmentary abnormalities characteristic of the epidermal nevus syndrome. The question is again asked whether patients with epidermal nevi have an increased incidence of tumors. It is suggested that the thorough evaluation of these patients as recommended by Solomon should also include an alertness for the development of earlier-than-anticipated neoplasms.
