“…The majority of colonic leiomyoma is asymptomatic and typically present as small polypoid intraluminal masses that can be removed endoscopically. 3,5,6 Less commonly, when symptomatic, abdominal pain is the most frequent presenting complaint, followed by a palpable mass or gastrointestinal bleeding. 4 reported another case of intraluminal leiomyoma resulting in intussusception and bowel obstruction.…”

The occurrence of leiomyoma of the colon is uncommon. Most of these lesions are clinically silent and are found incidentally during laparotomy or endoscopic procedures for unrelated conditions. Symptomatic leiomyomas of the colon are encountered less frequently, with only sporadic reports in the literatures. We describe a heretofore unreported case of a large extraluminal leiomyoma of the sigmoid colon presenting as massive lower gastrointestinal hemorrhage. Because it was extraluminal in position, it was difficult to make an accurate diagnosis endoscopically and the condition was easily misdiagnosed as angiodysplasia of the colon until CT scan results were seen. Although rare and benign in nature, leiomyoma of the colon may cause life-threatening complications that require emergency surgery and should be included in the differential diagnosis of lower gastrointestinal hemorrhage.

“…2 These tumors arising from the colon are extremely rare and represent only 3 percent of all gastrointestinal leiomyomas. 3 The descending and sigmoid colon seem to be the most frequent sites of its occurrence in the colon. 4 Clinical manifestations of colonic leiomyoma depend on the size and direction of its growth.…”

“…1 However, leiomyomas arising in the colon and rectum are rare, only 3% of all alimentary tract leiomyomas. 2 Colonic submucosal lesions, including leimyomas are usually treated by surgical resection, because endoscopic resection has a considerably higher perforation risk. 3 However, several case reports have shown that endoscopic resection of small polypoid leimyomas is feasible.…”

“…3 However, several case reports have shown that endoscopic resection of small polypoid leimyomas is feasible. 2,[4][5][6][7][8][9][10][11][12][13] Since screening colonoscopy for colorectal cancers became widely available, the detection of small polypoid leiomyomas by colonoscopy has increased. 14 In the present study, we evaluated clinicopatho-logical characteristics of colorectal polypoid leiomyomas and the efficacy and outcome of endoscopic removal of these lesions.…”

Background/Aims: Although polypoid leiomyomas in the colon and rectum are rare, they are increasingly detected during colonoscopy. The aim of this study was to evaluate the efficacy and clinical outcomes of endoscopic removal for colorectal polypoid leiomyoma. Methods: Data were retrospectively collected from 22 patients with polypoid leiomyoma arising from the muscularis mucosae in the colon and rectum who underwent endoscopic removal at single referral gastrointestinal endoscopy unit. Colonoscopic findings, endoscopic removal, success rates, complication rates (bleeding or perforation), pathologic characteristics, and recurrence rates were investigated. Results: Most polypoid leiomyomas were small asymptomatic lesions less than 1 cm. The tumors were located predominantly in the left colon. Ten leiomyomas were removed using cold biopsy forceps, and 12 were resected by conventional polypectomy or endoscopic mucosal resection. All tumors arose from or involved the muscularis mucosa. There were no complications, such as bleeding or perforation. No local remnant lesions were found in 19 patients who underwent at least one follow-up colonoscopy. Conclusions: This case series represent cases of small colorectal polypoid leiomyoma that were safely removed endoscopically. An awareness of their endoscopic and clinic-pathological characteristics may provide safe treatment strategy for colonic leiomyomatous tumors of similar size in capable hands.

Obscure-occult bleeding: resolution of unexplained chronic sideropenic anaemia by colonoscopic removal of a colonic leiomyoma

BACKGROUNDSmooth muscle tumours of the gastrointestinal tract are uncommon, but those arising in the colon and rectum are rare and represent only 3% of all alimentary tract leiomyomas. 1 Several cases of endoscopic resection of colonic leiomyomas have been described. 2 3 Because conventional polypectomy of leiomyomas can result in perforation, the technique of submucosal injection polypectomy can be used to reduce the risk of this complication. We report a case of a woman affected by sigmoid leiomyoma in which complete enucleation was performed at the time of colonoscopy using this method.

Leiomyomatous colonic polyp

Abstract: Leiomyomatous colonic polyps are rare. We report a patient with an asymptomatic 15-mm submucosal polyp in the sigmoid colon. The tumor was successfully removed by endoscopy. Histopathological examination revealed a leiomyoma originating in the muscularis mucosa.
