This study details a rare esophageal leiomyosarcoma case, possibly originating from the muscularis mucosae. The unusual intraluminal polypoid tumor presented diagnostic challenges, highlighting the need for thorough histopathological evaluation.

Area of Science:

  • Gastroenterology
  • Surgical Pathology
  • Oncology

Background:

  • Esophageal leiomyosarcomas are rare mesenchymal tumors.
  • Distinguishing leiomyosarcoma from other esophageal tumors can be challenging.
  • Tumors arising from the muscularis mucosae are exceptionally uncommon.

Observation:

  • A 68-year-old male presented with dysphagia due to a large, intraluminal, polypoid lesion in the distal esophagus.
  • Initial computed tomography (CT) suggested carcinosarcoma due to lack of exophytic component, despite biopsy confirming leiomyosarcoma.
  • Subtotal esophagectomy was performed for definitive treatment.

Findings:

  • Microscopic evaluation confirmed esophageal leiomyosarcoma without muscularis propria invasion or carcinomatous components.

  • The tumor exhibited a pedunculated, intraluminal growth pattern, originating unusually from the muscularis mucosae.
  • Review of this case and three prior reports provides insights into pedunculated esophageal leiomyosarcomas.

    • Implications:

    • This case expands the understanding of esophageal leiomyosarcoma origins and presentations.
    • Accurate preoperative diagnosis is crucial for appropriate surgical planning and management.
    • Further research into rare esophageal mesenchymal tumors is warranted.
