AbstractThe patient was a 79-year-old male. At three years and eight months after his initial presentation, upper gastrointestinal endoscopy revealed a black-flattened elevated lesion in the middle third of the esophagus, which was diagnosed as malignant melanoma on biopsy. No lymph node or distant metastasis was found. A diagnosis of cT1bN0M0 Stage I was thus made. We performed a robot-assisted, minimally invasive esophagectomy and D2 dissection. The postoperative diagnosis was pT1a-MM, N0, M0, vascular invasion+, stage 0. The patient was recurrence-free for 14 months after surgery. We presume that an aggressive biopsy diagnosis is important for the early detection of malignant melanoma.
