Insights
Malignant lymphoma causing ileocecal intussusception is rare in adults. Laparoscopic surgery offers a safe and effective option for diagnosis and treatment of these rare adult intussusception cases.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Intussusception is the telescoping of one segment of the intestine into another.
- While common in children, adult intussusception is rare and often associated with underlying pathology, such as malignancy.
- Malignant lymphoma as a cause of intussusception in adults is particularly uncommon.
Observation:
- A 22-year-old male presented with right lower abdominal pain, leading to the discovery of a ball-like ileal tumor.
- Imaging revealed ileocecal intussusception, with biopsy confirming malignant lymphoma.
Findings:
- Histologic examination identified the tumor as diffuse large B-cell lymphoma.
- Laparoscopic ileocecal resection was performed successfully.
Implications:
- Malignant lymphoma is a rare cause of intussusception in adults.
- Laparoscopic resection is a safe and viable option for diagnosing and treating ileocecal intussusception in adults when feasible.
Abstract:
A 22-year-old man was admitted with right lower abdominal pain. Colonoscopy revealed a ball-like tumor at the ileum. Abdominal sonography and computed tomography showed ileocecal intussusception. Microscopic examination of the biopsy specimen showed malignant lymphoma. Laparoscopic ileocecal resection was performed. Histologic diagnosis of the resected tumor was diffuse large B cell-type malignant lymphoma. Intussusception due to malignant lymphoma is relatively rare in adults. If contraindications of laparoscopy are not present, laparoscopic resection can be performed safely and should be considered for diagnosis and treatment for intussusception in ileocecal lesions in adults.
