Enteric duplication cyst associated with melanosis peritonei.
Melanosis peritonei is usually associated with benign cystic teratomas of the ovary. We describe a one-and-a-half-year-old girl with melanosis peritonei associated with enteric duplication cyst. Melanophages were seen in aggregates in and around the serosal blood vessels, nerve bundles, and scattered within the muscular wall of the cyst. Presence of hyperplastic nerve bundles associated with melanophages suggests their origin from the neural crest.
