Hematoxylin and eosin staining of the pathology slide. The submitted sample is a polypoid formation measuring 1.8×0.8×0.6cm with a short pedicle. The performed cuts (A, B, C, D) are stained with hematoxylin and eosin; magnification ×25. They show a benign hamartomatous polyp, containing multiple partially calcified schistosoma eggs (1); the stroma contains smooth muscular fibers (2) intermingled with the branching and variably oriented glands (3); these glands are lined by intestinal-type epithelium with predominant goblet cells and few paneth cells at the bottom of these glands.
