ALVAREZ U, RIMSKY et al. Primary esophageal melanoma. Report of one case. Rev Chil Cir [online]. 2009, vol.61, n.2, pp. 168-170. ISSN 0718-4026. doi: 10.4067/S0718-40262009000200010.
Primary malignant melanoma of the esophagus is an extremely rare tumor. Less than 300 cases have been published worldwide. Although surgical excision is the best possible therapeutic option, the prognosis is poor. We report a 70 years oíd man, who underwent an esophagoscopy due to a 6-months history of dysphagia and upper abdominal discomfort. There was no history of previous cutaneous melanoma. A polypoid and pigmented mass (of 5 cm diameter) almost completely occluding the lumen in the lower fhird of the esophagus, was found. The histological diagnosis of the initial biopsy was melanoma. Transhiatal esophagectomy was performed and the esophagus was replaced by an isoperistaltic gastric tube with cervical esophageal anastomosis. The excised specimen showed a polypoid tumor with black pigmentation of 5.5 cm. The diagnosis of pathological and immunohistochemical studies was a primary esophageal malignant melanoma. The resection margins of esophagus were free of tumor. He received no postoperative adjuvant therapy and signs of recurrence were observed 3 months after the operation.
