Summary
Colonic lipomas are rare, benign tumors. This case highlights a large, ulcerated cecal lipoma mimicking malignancy, necessitating surgical removal.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Colonic lipomas are uncommon mesenchymal tumors originating from adipose tissue.
- Typically asymptomatic and incidentally discovered, large lipomas can cause significant symptoms.
- These large lesions can mimic malignant tumors, leading to misdiagnosis and unnecessary surgeries.
Purpose of the Study:
- To report a case of a large, ulcerated cecal lipoma.
- To discuss the diagnostic challenges and management of symptomatic colonic lipomas.
- To emphasize the role of surgery in managing large or complicated colonic lipomas.
Main Methods:
- Case report of a 68-year-old woman with abdominal pain and weight loss.
- Radiological and endoscopic evaluation revealing a lesion suspicious for malignancy.
- Surgical intervention via laparoscopic right-hemicolectomy.
Main Results:
- A large, broad-based, ulcerated cecal lipoma was identified.
- The lesion was histopathologically confirmed as a submucosal lipoma.
- Laparoscopic right-hemicolectomy was successfully performed.
Conclusions:
- Large colonic lipomas, particularly when ulcerated, can present diagnostic challenges.
- Surgical resection is the definitive treatment for symptomatic or complicated colonic lipomas.
- Early and accurate diagnosis is crucial to avoid aggressive, unwarranted interventions.

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
