“…Sarcomas are malignant tumors that arise in the connective tissues, account for <1% of all adult cancers, and arise in the soft tissues in at least 70% of cases [ 3 ]. The most common sites of digestive leiomyosarcomas are the small intestine (45%) and the colon (38%) [ 4 ]; these tumors are most often diagnosed in middle-aged patients (50–60 years old), with a slight male preponderance [ 4 ].…”

A 66-year-old man presented to our institution with a positive fecal occult blood test and lower abdominal pain. Although a tumor was found in the sigmoid colon, biopsy and imaging studies failed to enable the diagnosis of the cancer, and the patient underwent surgery for treatment and diagnosis. The tumor had two distinct areas with differing features shown both histopathologically and on imaging; it was thus diagnosed as a leiomyosarcoma of the sigmoid colon with a pleomorphic component. Here, we describe a rare case of leiomyosarcoma of the sigmoid colon with a pleomorphic component. There are no reports of leiomyosarcoma with pleomorphic components arising in the colon in the literature; thus, the recurrence and metastatic characteristics are unknown. Therefore, accumulating cases in the literature may provide valuable insights into diagnosing and treating these rare tumors.
