Area of Science:

  • Oncology
  • Pediatric Oncology
  • Gastrointestinal Surgery

Background:

  • Mesenteric leiomyosarcoma is a rare malignancy, typically affecting middle-aged adults.
  • Primary mesenteric tumors are uncommon in pediatric and adolescent populations.
  • Accurate preoperative diagnosis of mesenteric soft tissue tumors presents significant challenges.

Observation:

  • A 13-year-old boy presented with a rare case of leiomyosarcoma originating from the ileal mesentery.
  • The tumor's location and rarity in this age group complicated initial assessment.
  • Clinical presentation often lacks specific indicators for early detection.

Findings:

  • Histopathologic evaluation was crucial for definitive diagnosis.
  • Immunohistochemical staining confirmed the neoplastic nature and cell type.
