Summary
A rare rectal cavernous hemangioma mimicked rectal cancer in a 59-year-old woman. This case highlights the importance of considering benign vascular lesions in rectal cancer differential diagnoses.
Area of Science:
- Gastroenterology
- Vascular Surgery
- Oncology
Background:
- Rectal cancer is a common malignancy requiring accurate diagnosis.
- Cavernous hemangiomas are rare benign vascular tumors that can occur in the rectum.
Observation:
- A 59-year-old woman presented with symptoms leading to a rectoscopic examination.
- The rectoscopic examination suggested a diagnosis of rectal cancer.
Findings:
- Histopathological examination revealed a diffuse rectal cavernous hemangioma, not rectal cancer.
- The hemangioma's appearance mimicked malignant rectal tumors.
Implications:
- This case underscores the necessity of including rare benign conditions in the differential diagnosis of rectal masses.
- Accurate differentiation between hemangioma and rectal cancer is crucial for appropriate patient management and treatment planning.
