Rare case of primary leiomyosarcoma of the colon
Abstract
Primary colon leiomyosarcomas (LMS) are rare malignant tumors of the gastrointestinal tract that occur in smooth muscle cells within the muscular or musculoskeletal layer of the intestinal wall, characterized by high aggressiveness and an unfavorable prognosis. These neoplasms cause difficulties in the primary differential diagnosis with other mesenchymal tumors of the gastrointestinal tract. In addition, preoperative diagnosis is difficult due to the fact that the clinical signs and data of radiation diagnostic methods are not specific. The presented case study describes a case of primary LMS of the sigmoid colon in a 68-year-old man. The observation is a set of clinical data, radiation diagnostic methods and histological examination of the tumor. Based on the results of the examinations, indications for surgical treatment in the form of laparoscopic resection of the sigmoid colon with lymph dissection were determined for the patient. The final diagnosis was made on the basis of a pathomorphological examination of the resected tumor and regional lymph nodes, since the radiological signs and clinical manifestations, as mentioned above, are not specific.
