A newborn with nodular ulcerated lesion on a giant congenital nevus.
The proliferative nodule is a lesion that develops within a congenital nevus. It is usually small (less than 5 mm), sometimes multiple, with a slow growth rate, and has a black or dark brown, smooth, shiny surface. It usually involutes spontaneously. We report a newborn infant who, at birth, had a giant congenital nevus with a nodular, ulcerative, hemorrhagic lesion within it. Physical and neurologic examinations were normal. Radiologic studies at birth and subsequently were normal. A fragment of the lesion was biopsied and histologic findings were compatible with a diagnosis of proliferative nodule in a giant congenital nevus. The rest of the nodule regressed spontaneously after 4 months.
