Summary
A rare solitary neurofibroma of the transverse colon was found in a patient without neurofibromatosis. This intussuscepting tumor caused massive lower gastrointestinal bleeding, representing a unique clinical presentation.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Background:
- Solitary neurofibromas of the colon are rare tumors.
- Neurofibromas typically occur in patients with neurofibromatosis.
Observation:
- A patient presented with massive lower gastrointestinal bleeding and an intussuscepting tumor prolapsing transanally.
- Imaging and subsequent surgical resection confirmed a solitary neurofibroma of the transverse colon.
Findings:
- Histopathological examination confirmed the diagnosis of a solitary neurofibroma.
- The tumor was successfully resected, and the patient recovered without complications.
Implications:
- This case highlights the importance of considering rare colonic tumors in the differential diagnosis of lower gastrointestinal bleeding.
- It underscores the rarity of isolated colonic neurofibromas, with this being only the second documented case.
