Area of Science:

  • Gastroenterology
  • Oncology
  • Pathology

Background:

  • Primary malignant melanoma of the esophagus is an exceptionally rare neoplasm.
  • It carries a typically fatal prognosis, with limited documented cases globally.

Observation:

  • A 76-year-old male presented with dysphagia and weight loss.
  • Esophagoscopy revealed a large, pigmented, polypoid mass in the lower esophagus.
  • No prior history of cutaneous melanoma or ocular abnormalities were noted.

Findings:

  • Histological and immunohistochemical analysis (HMB-45, S-100 positive) confirmed primary esophageal malignant melanoma.
  • The diagnosis was established preoperatively through endoscopic biopsies and confirmed post-resection.

Implications:
