Abstract
Here we report a case of a 61-year-old otherwise healthy man presented to our hospital complaining of intermittent colicky pain of left-sided abdomen, bloating and constipation lasting for last month. He had no previous abdominal surgeries or significant problems in his past medical history. Physical examination revealed mild anemia and abdominal tenderness. The patient’s hemoglobin level was 11.8 g/dL and his carcinoembryonic antigen level (CEA) was normal; Erythrocyte sedimentation rate (ESR) was 28 mm/hr and C-reactive protein (CRP) was 0.7 mg/dL.
Contrast-enhanced abdominal computed tomography (CT) revealed the presence of a concentric mass in the descending colon with a density of approximately -100 Hounsfield units (Fig. 1,2). A colonoscopy was performed for a better assessment which revealed a giant submucosal mass on the descending colon that encompassed more than 75% of the bowel lumen (Fig. 3). Biopsy was performed and histopathologic examination of the specimens showed reactive changes without evidence of dysplasia or malignancy but definite diagnosis could not be made. The patient underwent a segmental colonic resection by laparotomy because of the mass size and the inability to rule out a malignancy. Pathological examination of the surgical specimen showed mature adipocytes in the submucosa with mucosal ulceration without signs of malignancy. Four days after surgery, the patient was asymptomatic and discharged.
