title: Primary malignant melanoma of the esophagus.
abstract: Primary malignant melanoma of the esophagus is an uncommon but aggressive tumor with fatal prognosis. We present 2 male patients with a history of dysphagia for a period of time and describe the imaging features of esophagograms and chest computed tomography (CT) scan. Both were proved by endoscopic biopsy. One of them underwent surgical resection. Primary malignant melanomas of the esophagus should be included in the differential diagnosis of bulky and polypoid masses that expand the esophagus without causing obstruction on esophagograms and chest CT scan.
