Esophageal melanocytosis is a rare entity defined by the proliferation of a melanocytic basal layer of the esophageal squamous lining and deposition of melanin in the esophageal mucosa. Esophageal melanocytosis is considered a benign entity of unknown etiology; however, it has been reported as a melanoma precursor. We report a case of esophageal melanocytosis in a diabetic and hypertensive 67-year-old male with recurrent dizziness and syncope for the past 6 months.

Article Synopsis
- A 62-year-old man was diagnosed with right hypopharyngeal cancer in 2019 and subsequent esophageal melanosis was found during an upper GI endoscopy.
- In February 2021, follow-up testing revealed that he had developed esophageal primary malignant melanoma, though scans showed no spread of the cancer.
- He underwent surgery to remove the affected area and is now regularly monitored as an outpatient without any signs of recurrence, highlighting the importance of careful follow-up for esophageal melanocytosis to catch any early signs of melanoma.
