Abstract
Waldenstrom macroglobulinemia (WM) is a neoplastic disorder of the B-cell lymphoid system. A 69-year-old man with WM presented with diarrhea for 6 months. Magnetic resonance enterography showed thickening of the terminal ileum (TI). Colonosocopy with TI intubation showed a single TI ulcer, and small bowel enteroscopy revealed multiple ulcers in the TI. Biopsies from both were negative on hematoxylin and eosin staining. Immunoglobulin M immunofluorescence staining of the ulcers was positive for IgM deposits consistent with WM. After 6 cycles of chemotherapy with bendamustine and rituximab, symptoms resolved.
