Esophageal Melanocytosis as a Rare Disease of Esophagus

Abstract

Esophageal melanocytosis is an extremely rare condition characterized by melanocyte proliferation in the esophageal squamous epithelium. The etiology and pathogenesis of the disease are unclear. Although it is thought to be a benign condition, there are publications reporting that it may be a precursor of malignant melanoma. In this report, we present a case with esophageal melanocytosis along with a literature review.
