Summary

This study reports a rare case of gastrointestinal stromal tumors (GISTs) with metastasis exclusively to the mesentery. The unusual presentation mimicked leiomyomatosis peritonealis disseminata, highlighting a unique GIST spreading pattern.

Area of Science:

  • Oncology
  • Gastroenterology
  • Pathology

Background:

  • Malignant gastrointestinal stromal tumors (GISTs) can metastasize, often to the peritoneum.
  • Diffuse mesenteric metastasis as the sole site of spread is exceptionally rare in GIST.

Observation:

  • A 69-year-old woman presented with multiple nodules confined to the mesentery.
  • The nodules spared the surfaces of the small and large bowel, omentum, and abdominal wall.
  • The presentation resembled leiomyomatosis peritonealis disseminata.

Findings:

  • Histological and immunohistochemical analyses confirmed the diagnosis of GIST.
  • The GIST exhibited a unique and rare pattern of mesenteric-only dissemination.

Implications:

  • This case expands the understanding of GIST metastatic patterns.
  • Recognizing this rare presentation is crucial for accurate diagnosis and treatment planning.
  • Further research may elucidate the mechanisms behind this specific GIST spread.
