“…Hence, tumor size, site, histological appearance, and mitotic count should be considered to predict the malignant potential of these colonic smooth muscle tumors [1]. Most colonic leiomyomas with absent histologic testing are often misdiagnosed as epithelial polyps because they present as solitary sessile intramural or intraluminal polyps [6,7].…”

Leiomyomas in the colon are uncommon accounting for a few cases of gastrointestinal smooth muscle tumors. These tumors are usually benign and asymptomatic. They may present with abdominal pain, intestinal obstruction, perforation, and rarely hemorrhagic, especially when the tumor is large. We present the case of a sigmoid leiomyoma in a 60-year-old patient consulting for a positive fecal occult blood test. Colonic leiomyomas should be considered in the differential diagnosis when a polyp is found during routine endoscopic evaluations. This case also highlights the limitations of diagnosing the nature of polyps using endoscopy alone.

“…Colonic leiomyomas are often misdiagnosed. Several authors have noted that most colonic leiomyomas with sessile morphology mimic epithelial polyps in their gross appearance during colonoscopy [ 4 , 7 ]. Choi et al reported that 45.5% of colorectal leiomyomas (10 of 22 lesions) were accurately diagnosed based on their endoscopic features [ 7 ].…”

We describe two cases of leiomyoma in the colon that were diagnosed histologically after endoscopic resection. The first case was a 79-year-old Japanese woman who presented with a pedunculated polyp of 14 mm length at the splenic flexure. Preoperative diagnosis suggested a colonic mucosubmucosal elongated polyp. The second case was a 29-year-old Japanese woman who presented with a pedunculated polyp of 40 mm length at the hepatic flexure and had an ulcer on top of the polyp. Preoperative diagnosis suggested an inflammatory fibroid polyp. A pathological diagnosis of colonic leiomyoma was made after endoscopic resection in both cases. Both tumors were confirmed to originate, not from the proper muscle layer, but from the muscularis mucosae. These cases underscore that although colonic involvement is infrequent, leiomyomas can display pedunculated morphology in the colon rather than the typical gross appearance of gastrointestinal submucosal tumors seen with sessile morphology.

Leiomyomas are uncommon tumors of the gastrointestinal system, representing around 0.03% to 0.05% of all rectal tumors. They tend to have a benign biological behavior and are mostly asymptomatic. When leiomyomas are large in size, they can cause symptoms and complications, including abdominal pain, perforation, intestinal obstruction, and bleeding. We herein present a case of a 57-year-old male patient presenting for colonoscopic evaluation following a positive screening with a fecal occult blood test. The patient was found to have a 10 mm pedunculated polyp at the level of the recto-sigmoid junction, which was removed by hot snare polypectomy and was found to have spindle cells that were positive for desmin, consistent with the rare diagnosis of recto-sigmoid leiomyoma. That being said, this case evokes a rare entity that endoscopists should keep in mind when approaching a recto-colonic polyp.
