A 70-years-old male was referred to us due to bloody diarrhea and involuntary weight loss during the last 2 months. Laboratory workup revealed anemia, hypoalbuminemia, and elevated reactive-C-protein. Computed tomography documented a wall thickening of sigmoid colon. Colonoscopy revealed pleomorphic ulceration of the sigmoid and descending colon. Aphthous ulcers were seen in ilium. Histology revealed mucosal infiltration with small sized atypical lymphoid cells in the epithelium and lamina propria, with extensive epitheliotropism.
