Ascending Colon Leiomyoma: A Case Report of a Uncommon Case

Abstract

A small number of gastrointestinal smooth muscle tumors are caused by leiomyoma, which are uncommon in the colon. Typically, these tumors are benign and asymptomatic. They typically affect middle-aged and older populations. They are uncommon, making up about 3% of gastrointestinal leiomyomas. During a screening colonoscopy, a 52-year-old Saudi male revealed a little, 5-mm ascending colon polyp in this case report. The polyp was transported to the pathology laboratory after being removed using a hot snare polypectomy. The histopathology report confirmed the size of the polyp (5 mm), single, firm, gray-white, polypoid 0.5 cm nodule, and the findings were consistent with inflamed submucosal leiomyoma with inflamed and ulcerated surface. No findings are suggestive of malignant changes. In conclusion, A rare benign tumor, intestinal leiomyoma, can mimic several smooth muscle tumors, especially adnexal masses, making diagnosis difficult. Though nonspecific radiological abnormalities are conceivable, huge size and extra-colic growth increase the likelihood of a diagnosis. Computed tomography (CT) can help identify benign leiomyoma from leiomyosarcoma, but tissue diagnosis is best. Histoimmunopathology is crucial to diagnosis. Small and large colonic leiomyoma polyps can be treated by snare polypectomy and wide surgical excision with follow-up. For some leiomyosarcoma patients, surgery, radiation, and chemotherapy are the main treatments.
