case_images: On the 3rd hospital day, abdominal ultrasonogram demonstrated an echogenic lesion located in the supravesical space (Fig. 1), and abdominal CT scan disclosed a dilated small bowel loop filled with fluid and a round solid mass in the right anterior supravesical space (Fig. 2).
case_images: Resected specimen shows a well-established polypoid lesion located perpendicular to the plane of mucosa on the edge of mesenteric line of jejunum.

case_images: Grossly, it was a well-established polypoid mass (2.3x2.1x2 cm) located perpendicular to the plane of mucosa on the edge of the mesenteric line of the jejunum (Fig. 3).
case_images: The cross section of the tumor shows homogeneously pinkish-yellow with smooth glistening surface.

case_images: The cut surface of the polyp was homogeneously pinkish-yellow with smooth glistening surface (Fig. 4).
case_images: The mass shows that a loose fibrous stroma infiltrates the muscularis propria, and the variably-sized small blood vessels are observed within diffuse inflammatory infiltrates (hematoxylin and eosin, x40).

case_images: Loose fibrous stroma infiltrated the muscularis propria, and the variably sized small vessels were observed with diffuse inflammatory infiltrates, mostly eosinophils (Fig. 5, 6).
case_images: A richly vascularized cellular fibrocytic stroma with scattered inflammatory cells, mostly eosinophils, is shown (hematoxylin and eosin, x200).
