case_images: CT of the abdomen and pelvis with the red arrow demonstrating soft tissue mass extending into the mesentery with segmental thickening and high-grade stenosis of the mid and distal ileum, along with associated mesenteric lymphadenopathy and partial small bowel obstruction.

case_images: FIG1
case_images: The patient underwent a CT scan which showed segmental thickening and high-grade stenosis of the mid and distal ileum, a soft tissue mass extending into the mesentery with associated mesenteric lymphadenopathy, and partial small bowel obstruction (Figure 1).
case_images: Resected small bowel specimen containing three stenotic circumferential small bowel lesions (one clearly on display: see the red arrow) and multiple enlarged mesenteric lymph nodes (see the blue arrow).

case_images: A total of approximately 2 m of small bowel was resected to include the lesions described above, and a hand-sewn end-to-end anastomosis was formed (Figure 2).
case_images: Histopathology slide demonstrating the key features of MS; immature medium-sized myeloid cells with finely granular eosinophilic cytoplasm and typical cleaved/reniform nuclei with fine blastic chromatin and small nucleoli.

case_images: FIG3
case_images: The small bowel showed effacement of normal architecture along with mass forming diffuse infiltrate of neoplastic cells with cleaved nuclei, high nucleus-to-cytoplasmic ratio, and dispersed chromatin (Figure 3).
