title: Nevus cell aggregates in the placenta. A histochemical and electron microscopic study.
abstract: This is a report of the histochemical and ultrastructural analysis of nevus cell aggregates in the placenta from a neonate with a giant pigmented nevus. Although the distinction between aberrant migration of neural crest elements and blood-borne metastasis from the giant pigmented nevus is not readily resolved, the authors favor the former as an explanation of this unusual placental lesion.
