Summary

This study reports two cases of primary esophageal melanoma in elderly women, highlighting distinct growth patterns and diagnostic criteria for this rare cancer. Early detection relies on identifying atypical melanocytic activity and invasive growth in endoscopic and surgical samples.

Area of Science:

  • Gastroenterology and Oncology
  • Melanoma Research
  • Surgical Pathology

Background:

  • Primary esophageal melanoma is an exceptionally rare malignancy, posing diagnostic challenges.
  • Understanding its morphogenesis is crucial for accurate diagnosis and treatment strategies.
  • This report details two unique cases in elderly female patients.

Observation:

  • Two female patients, aged 63 and 68, presented with primary esophageal melanoma.
  • Histopathological examination revealed nodular and lentiginous growth patterns.
  • Diagnosis was established intraoperatively in one case and at autopsy in the other.

Findings:

  • Morphogenetic analysis indicated multiple, non-simultaneous tumor growth zones with apposition growth.
  • Early stages showed atypical borderline melanocytic activity and melanoma in situ.

  • The presence of incipient invasive growth was a key diagnostic criterion.

    • Implications:

    • Accurate diagnosis of primary esophageal melanoma requires careful evaluation of endoscopic and surgical specimens.
    • Recognizing early morphogenetic changes can improve diagnostic yield for this rare tumor.
    • Further research into the pathogenesis and treatment of esophageal melanoma is warranted.
