case_images: Axial contrast-enhanced CT scan showed a well-demarcated fatty mass lesion containing soft tissue attenuation in the mesentery of the jejunum (Figure 1).
case_images: Gross appearance of the tumor. The cut surface of the tumor is yellowish, well demarcated, and partially encapsulated and shows small nodules of firm white tissue, corresponding to smooth muscle. The tumor does not invade the jejunal wall.

case_images: There were no areas of hemorrhage or necrosis (Figure 2).
case_images: Microscopic findings of the tumor. (a) The tumor shows admixture of smooth muscle and mature adipocytes. (b) Widely dilated vessels and a thick wall vessel are seen within the tumor. (c) Smooth muscle cells are immunoreactive with alpha-smooth muscle actin.

case_images: Microscopically, the tumor consists of a mix of mature adipose tissue and bundles of the spindle cells, which had features of mature smooth muscle cells with regular cigar-shaped nuclei and bright fibrillary eosinophilic cytoplasm (Figure 3(a)). Characteristically, abundant dilated blood vessels were observed and a few thick walled vessels are also noted (Figure 3(b)).
