Surgical treatment of primary malignant melanoma of the esophagus: a case report.

Primary malignant melanoma of the esophagus (PMME) is an extremely rare tumor with only scattered cases reported. Although surgical resection has been considered as the best possible option, the prognosis has been nonetheless poor. We report a case of PMME which was treated by surgical resection and additionally followed by chemotherapy. A 60-yr-old man underwent an esophagoscopy due to a 3-month history of dysphagia and upper abdominal discomfort. A pigmented polypoid mass in the lower third of the esophagus was discovered, and a biopsy identified the mass as a malignant melanoma. Consequently, a subtotal esophagectomy and intrathoracic esophagogastrostomy was carried out. At follow-up four months after discharge, lymph node enlargements in the cervical area and celiac axis area were found. As a result, the patients was started on systemic chemotherapy treatment, which included Dacarbazine. The patient has been doing well and is now 35 months post-operative.
