ABSTRACT
This report presents an unusual case of primary malignant melanoma in the midesophagus. The patient was a 36-year-old woman presenting with dysphagia and odynophagia. The resected esophagus and proximal stomach showed a dark purple large polypoid mass, measuring 6.0 3.3 2.0 cm, with a diffuse tan pigmentation of surrounding mucosa in the mid-esophagus and two small daughter nodules, up to 1.2 0.3 cm, in the lower esophagus near the gastro-esophageal junction. A microscopic examination revealed a malignant melanoma of epithelioid cell type confined to mucosa and submucosa with a diffuse melanosis. Cytoplasmic immunoreactivity for HMB 45 and S-100 protein were noted. An electron microscopic examination revealed large, loosely cohesive variable shaped cells with a few cytoplasmic premelanosomes.
