Esophageal blue nevus: an isolated endoscopic finding.

Abstract

The occurrence of blue nevus has seldom been reported in extracutaneous sites and with no record in the esophagus. A blue nevus was reported in the esophagus of a 58-year-old Chinese woman. On endoscopic examination, the lesion presented as linear patches of bluish pigmentation in the esophagus. The patient was free of symptoms 3 years after the endoscopic examination. We believe this represents the first reported case of blue nevus in the esophagus. The clinicopathologic features, differential diagnoses, and the nature of the lesion are discussed, along with a review of the literature.
