“…Rarely, gastrointestinal lipomas may be intramucosal, such cases may rarely be associated with Cowden syndrome 58 . The reported incidence of large bowel lipomas is between 0.2% to 4.4% of endoscopies, with possible slight female predilection and a peak incidence in the 6th decade 59 . Signs and symptoms of GI lipomas are linked to size (highly variable from 2 to > 10 cm) and location.…”

Summary Mesenchymal tumours represent a heterogenous group of neoplasms encopassing benign, intermediate malignancy, and malignant entities. Sarcomas account for approximately 1% of human malignancies. In consideration of their rarity as well as of intrinsic complexity, diagnostic accuracy represents a major challenge. Traditionally, mesenchymal tumours are regarded as lesions the occurrence of which is mostly limited to somatic soft tissues. However, the occurrence of soft tissue tumours at visceral sites represent a well recognized event, and the GI-tract ranks among the most frequently involved visceral location. There exist entities such as gastrointestinal stromal tumours (GIST) and malignant gastointestinal neuroectodermal tumors that exhibit exquisite tropism for the GI-tract. This review will focus also on other relevant clinico-pathologic entities in which occurrence at visceral location is not at all negligible.

Aurora rings may not always indicate an inverted colonic diverticulum: Report of a rare case of colonic lipoma

Aurora rings are prominent endoscopic features of the inverted colonic diverticulum (ICD), and their appearance alongside a colonic lipoma is an unprecedented phenomenon. The present study reports a case of colonic lipoma with Aurora rings, contradicting the assumption that Aurora rings are indicative of ICD. A 52-year-old male patient presented with left-sided abdominal pain for >1 year, associated with constipation in the form of the decreased frequency of bowel motions every 4 to 5 days. A physical examination revealed an obese, protuberant abdomen and a mildly tender left iliac fossa region without other notable findings. A transabdominal ultrasonography revealed a thickening of the large bowel wall (<7 mm) with a suspected inflammatory lesion on the left side of the colon. During an ileocolonoscopy, multiple diffuse diverticula of various sizes were observed, affecting the entire colonic mucosa. Furthermore, a large (1.5 cm) pedunculated polyp with a thick stalk was found in the sigmoid colon, exhibiting positive Aurora rings. A polypectomy was conducted with the deployment of two hemoclips at the polyp base to prevent perforation. The histopathological examination of the specimen, a 1.3 cm polyp, revealed the presence of a colonic lipoma, rather than an ICD. The identification of Aurora rings has emerged as a significant endoscopic feature in the diagnosis of ICD; nevertheless, the underlying etiology of these rings remains elusive. Based on an extensive search of the literature, no study was found mentioning the appearance of Aurora rings in an endoscopic screening of other colonic conditions other than ICD. The appearance of Aurora rings alongside a colonic lipoma has not previously been mentioned, at least to the best of our knowledge, which renders the differentiation of ICD from lipomas and polyps more challenging.

“…Although it is a benign, nonepithelial tumor, the complication of bowel obstruction can be life-threatening [1]. Colonic lipomas can present challenges in the preoperative differential diagnosis between malignant and benign colonic neoplasms, which is the main problem associated with lipomas [2].…”

Lipomas of the colon are benign tumors of the digestive tract. They are usually asymptomatic, and often discovered incidentally during a colonoscopy. However, lipomas larger than 2 cm may present with abdominal pain, bowel changes, and rectal bleeding. They may mimic cancer, depending on multiple factors including tumor size, location, and complications, which often makes preoperative diagnosis difficult. In this report, we discuss the case of a 34-year-old woman who presented with paroxysmal abdominal pain in the left iliac fossa with moderate hematochezia that had been evolving for six months. The patient denied melena or hematemesis, and she had no significant medical history. Colonoscopy revealed a large polyp of over 5 cm located 40 cm from the anal margin. She underwent endoscopic resection without complications. The histological examination confirmed the lipomatous nature.An accurate preoperative diagnosis of lipomas is necessary. It can often be difficult to choose between endoscopic and surgical treatment. The choice of treatment depends on the size and location of the tumor and complications. Endoscopic resection may obviate the need for surgery and can potentially reduce surgical morbidity. We aimed to report and discuss the management of this patient who underwent endoscopic resection for a large mass with a definitive pathology of colonic lipoma.
