Abstract
Primary malignant melanoma of the esophagus is a rare disease with a severely poor prognosis. Here, we report a patient with primary malignant melanoma of the esophagus surviving without recurrence after surgery and adjuvant therapy with nivolumab. The patient was a 60-year-old female with dysphagia. Esophagogastroscopy showed an elevated dark brown tumor in the lower thoracic esophagus. A histological examination of the biopsy revealed human melanoma black 45 and melan-A positivity. The patient was diagnosed with primary malignant melanoma of the esophagus and was treated with radical esophagectomy. As postoperative treatment, the patient was given nivolumab (240 mg/body) every 2 weeks. Although bilateral pneumothorax occurred after 2 courses, she recovered after chest drainage. Nivolumab treatment is still ongoing over 1 year after the surgery, and the patient has survived without recurrence. We conclude that nivolumab is an optimal option as a postoperative adjuvant treatment for PMME.

Abstract
Primary malignant melanoma represents the fifth most common cancer in the United States. It is subdivided into two forms: cutaneous (90%), visceral (8%, including ocular and mucosal) and of unknown primary (2%). The vast majority of gastrointestinal melanomas are secondary lesions until proven otherwise. Primary esophageal melanoma in particular is exceedingly rare, less than 200 cases have been documented in the literature to date. It is highly prevalent in Japan and occurs twice as much in men than women around the 6th decade of life. It has a predilection for the middle and lower esophagus, with only 6 cases occurring at the gastroesophageal junction worldwide. Its etiology and pathogenesis are poorly understood, and no curative treatment has been established given the paucity of cases. We present a case of primary melanoma of the gastroesophageal junction which represents the 2nd incident case in the united states and 7th worldwide.
