Summary
Gastrointestinal haemangiomas are rare intestinal neoplasms. This case report details a unique instance of a small bowel haemangioma with associated mesenteric lymph node involvement, a previously unreported finding.
Area of Science:
- Gastroenterology
- Pathology
- Surgical Oncology
Background:
- Gastrointestinal haemangiomas are uncommon intestinal neoplasms, accounting for 0.05% of all such tumors.
- These benign vascular tumors typically manifest with symptoms like pain, bleeding, and obstruction.
- Previous literature has not documented hemangiomatous changes in regional lymph nodes associated with gastrointestinal hemangiomas.
Observation:
- A 21-year-old female presented with abdominal pain and vomiting.
- Imaging studies (ultrasound and CT scan) revealed a lower abdominal mass.
- Laparotomy identified a small bowel tumor causing intussusception and enlarged mesenteric lymph nodes.
Findings:
- Pathological examination confirmed a small bowel hemangioma.
- Mesenteric lymph node involvement by hemangiomatous change was identified.
- Hamartomatous change was determined to be the likely cause of lymph node involvement.
Implications:
- This case expands the known clinical presentation of gastrointestinal hemangiomas.
- It highlights the possibility of mesenteric lymph node involvement in these rare tumors.
- Understanding the pathogenesis of lymph node hemangiomatosis is crucial for accurate diagnosis and management.
