Colonic lipomas are rare submucosal tumors. This case highlights a colonic lipoma covered by hyperplastic epithelium, initially misdiagnosed as an epithelial lesion during colonoscopy.
Area of Science:
- Gastroenterology
- Gastrointestinal Pathology
- Surgical Oncology
Background:
- Colonic lipomas are benign submucosal tumors, typically asymptomatic.
- Mucosal alterations over lipomas are uncommon but can include hyperplasia, adenoma, atrophy, ulceration, and necrosis.
Observation:
- A 68-year-old woman presented with a colonic lesion identified during colonoscopy.
- The lesion was initially presumed to be an epithelial neoplasm based on endoscopic appearance.
Findings:
- Histological examination revealed a submucosal colonic lipoma.
- The lipoma was covered by hyperplastic colonic epithelium, mimicking an epithelial lesion.
Implications:
- This case underscores the importance of histological examination for accurate diagnosis of colonic submucosal lesions.
- Understanding the varied mucosal presentations of colonic lipomas is crucial for appropriate endoscopic and surgical management.
