Diagnosis and Surgical Outcomes for Primary Malignant Melanoma of the Esophagus: A Single-Center Experience

Despite the similarity in lymph node metastatic patterns to squamous cell carcinoma, PMME is more inclined to distant metastasis. Clinical staging was inconsistent with pathological staging for PMME based on endoscopy and computed tomography. Surgical therapy was the optimal treatment for PMME at an earlier stage. Early diagnosis and aggressive lymph node dissection were beneficial for accurate staging, potentially reducing recurrence and thus improving survival.
