Colonic lipomas are benign tumors originating in mesenchymal tissue and are considered the second most common benign tumor in the colon after adenomatous polyps. They tend to affect women more; their most frequent location is the right colon. Generally, these lipomas do not exhibit symptoms, but when they reach a considerable size, they can cause manifestations. They can also result in complications such as obstruction, intussusception, and perforation.

Since their radiological characteristics are similar to fat, they can be visualized using computed tomography. Still, the final diagnosis is made through colonoscopy, where a fatty mass with an oval shape and elastic capacity is observed. Lesions can be removed endoscopically or surgically. Spontaneous expulsion of a lipoma rectally is rare, and its mechanism is not yet fully understood. Although the literature establishes a cut-off point of 2 cm to decide between endoscopic or laparoscopic resection, the former is increasing and can extend this limit. Surgical resection is recommended in cases such as the one in this article. This case is the biggest reported colonic lipoma (13 cm) expelled spontaneously.
