title: Esophageal Melanocytosis - An Unusual Melanocytic Entity.
abstract: Esophageal melanocytosis is a rare benign condition characterized by melanocytic proliferation in esophageal squamous epithelium and melanin deposition in the mucosa. Because of its uncommon nature, pathologists and gastroenterologists lack experience with this entity. We present a case of esophageal melanocytosis in a 66 years old male patient who presented with atypical chest pain and dysphagia. Endoscopic guided biopsy was done, provisional diagnosis of esophageal melanocytosis was made. Bleaching and immunohistochemistry confirmed the diagnosis.
