Can colon lipomas be cancerous?
Large lipomas may develop superficial ulceration and bleeding and may present with a combination of symptoms. Due to similarities in age and symptoms, colonic lipomas may mimic malignancy in presentation.
Can lipoma cause bowel problems?
The most common presentations of symptomatic patients with lipomas greater than 2 cm in size include abdominal pain, hemorrhage, diarrhea, or constipation. Lipomas that grow more than 4 cm in size can lead to obstruction and intussusception requiring surgical or endoscopic resection.
What is a lipoma in the sigmoid colon?
Lipomas of the colon are relatively rare benign tumors of mesenchymatic origin. They are usually asymptomatic but as they become larger they can cause symptoms including abdominal pain, diarrhea, nausea, constipation, haematochezia, loss of body weight, anemia or even intussusception and colonic obstruction.
Can you get a tumor on the outside of your colon?
Your doctor may also call it metastatic or stage IV disease. Although it’s outside your colon or rectum, it’s still colorectal cancer, and doctors treat it with drugs for that disease. For most people, there’s no cure. But treatments can help you feel better and live longer.
What can a mass in the colon mean?

What are colonic lipomas of the large intestine?
Lipomas of the large intestine are most commonly seen (in order of decreasing frequency) in the cecum, ascending colon, and sigmoid colon. Of note, more than 70% of these tumors are located in the right hemicolon. Colonic lipomas are more common in women than in men, with a predilection for the right colon in women and the left colon in men.
Which CT findings are characteristic of pericolic fat stranding in colon cancer?

What is a fatty lump on the skin?
A lipoma is a slow-growing, fatty lump that’s most often situated between your skin and the underlying muscle layer. A lipoma, which feels doughy and usually isn’t tender, moves readily with slight finger pressure. Lipomas are usually detected in middle age. Some people have more than one lipoma.
Do lipomas in the colon hurt?
Lipomas themselves do not cause pain, but their location may cause problems. When external lipomas grow near nerve endings, they can cause pain by putting pressure on the nerve. Pain may also be caused by lipomas that contain a large number of blood vessels. Most internal lipomas found in the colon are small and cause few issues.
