(a) Histologic section of small bowel (H&E). On the left, this low-power view shows normal intestinal villi protruding into the bowel lumen. On the right, beneath the villi, is a disorganized spindle-cell lesion. (b) Histologic section of small bowel (H&E). Extravasated blood is a prominent feature within the spindle-cell lesion, in this medium-power view. (c) Histologic section of small bowel (H&E). Small spaces, sometimes slit-like, are present within the spindle-cell proliferation. Mitotic activity is readily identified. (d) Histologic section of small bowel (HHV-8 immunostain). There is strong nuclear staining of the tumour cells.
