title: The Diagnosis of Sigmoid Liposarcoma in a Young Male with Metabolic Syndrome.
abstract: The clinical picture and risk factors are decisive in differential diagnosis. It was proved that patients with metabolic syndrome have increased incidence of malignant tumours. The visceral adipose tissue releases active proteins that promote oncogenesis. We are presenting a case of 34-year-old male with metabolic syndrome suffering from pain in left iliac fossa with accompanying variable stool pattern. At first, the sigmoid diverticulosis was suspected. Patient's condition after the treatment has improved. The ambulatory, partial colonoscopy revealed a cauliflower-like, balloting, wide-base growth in the sigmoid that narrowed its lumen. The biopsy did not reveal atypical growth characteristics. Because of tumour type and enlarged regional lymph nodes seen in abdomen CT scan, the segmental colon resection and end-to-end anastomosis was performed in the area of sigmoid-rectal junction. Macroscopically, there were no visible metastases in the operation field. The surgery and postoperative period ran without any complications. On histopathological examination, the removed tumour was a well differentiated liposarcoma (WDL) stemming unusually from adipose tissue of colonic submucosa in an obese male. WDL is a hard to diagnose tumour, especially in early stages of its growth. In the presented case, the tumour was completely resected.
