Ileo-ileal intussusception caused by lymphangioma of the small bowel treated by single-incision laparoscopic-assisted ileal resection

Figure 1 Computed tomography of abdomen: Computed tomography revealed an ileo-ileal intussusception. The leading point revealed hypovascular mass measuring 1 cm in a diameter.

Figure 2 The lesion was externalized using forceps and hands through the umbilical incision.

Figure 3 Leading point of intussusception was palpable and soft mass was confirmed.

Figure 4 Microscopic findings of the resected specimen. Polycystic mass with convolutional pattern was found. Cutting lines are shown by lines.

Figure 5 Microscopic findings: Cysts were lined by a flat epithelial endothelium. No blood cells were found.

Figure 6 Immunohistochemical examination: The endothelial cells were partially positive for D2-40 (A) and CD34 (B).
