Figure 3. A 77-year-old man with a pulse granuloma of the descending colon. (A) Low-power photomicrograph of the histopathology of the excised descending colon nodule shows a benign granulomatous and fibrotic nodule, or pseudotumor, containing a legume seed in the center. There is no evidence of malignancy. Hematoxylin and eosin (H&E). Original magnification. (B) A higher-power photomicrograph shows the central legume seed, typical of a pulse granuloma. H&E. Magnification ×15.
