Focal circumferential wall thickening of the left side of the jejunum caused moderate intraluminal narrowing, with evidence of small bowel obstruction (Fig. 1).
High-power photomicrograph (400x, hematoxylin and eosin stain) of the pelvic mass revealed the aggregations of histiocytes with granular eosinophilic cytoplasm (von Hansemann histiocytes), many of which contained basophilic inclusions (Michaelis-Gutmann bodies) (arrows), typically spherical, 5-8 microm, and concentrically laminated bodies with a bull's-eye appearance.
