Duodenal leiomyosarcomas can appear benign but often recur. Large tumors and limited surgical resection are linked to poor outcomes, highlighting the need for careful treatment strategies.

Area of Science:

  • Gastrointestinal Oncology
  • Surgical Pathology

Background:

  • Leiomyosarcomas are rare mesenchymal tumors.
  • Duodenal leiomyosarcomas are exceptionally uncommon, often presenting diagnostic challenges.

Observation:

  • Two duodenal leiomyosarcoma cases presented with benign gross and histologic features.
  • Despite initial benign appearance, both patients experienced tumor recurrence and poor outcomes.

Findings:

  • A review of six cases (including the two presented) revealed associations between large tumor size, limited surgical resection, and adverse outcomes.
  • Local recurrence was a frequent complication in cases with inadequate resection.
  • A 6% rate of lymphatic metastasis was observed, suggesting potential for systemic spread.

Implications:

  • These findings underscore the importance of considering leiomyosarcoma in duodenal tumors, even those with seemingly benign characteristics.
  • Aggressive surgical resection may be necessary for optimal outcomes, despite initial histologic assessment.
  • The potential for lymphatic metastasis warrants consideration in surgical planning and follow-up protocols.
