Benign Müllerian Papilloma of Childhood

Abstract

Benign müllerian papilloma of the female reproductive tract is a rare childhood tumor that can easily be mistaken by those unfamiliar with the entity for botryoid rhabdomyosarcoma. Ultrastructural findings have been mentioned only in two individual case reports, and these both were issued many years ago. The aim of this update is to familiarize the reader with the clinical, light, and electron microscopic features associated with this distinctive entity, and thereby hopefully preclude the risk of making a serious diagnostic error. Two cases are illustrated, one very typical in its presentation and the other less so.
