Excision of a large abdominal wall lipoma improved bowel passage in a Proteus syndrome patient

Figure 1 Clinical findings of the abdomen. There was a child-head sized mass at the left lower abdomen (arrows).

Figure 2 A preoperative plane abdominal X-ray examination indicated that colon gas in the left colon (arrows) was shifted to the upper right side.

Figure 3 Preoperative computed tomography (CT) of the abdomen. A large mass in the subcutaneous adipose tissue in the left lower abdominal wall was identified (arrows) and this encased the peritoneal organs to the right side.

Figure 4 Histopathological findings of the excised mass. Lobular arrangement of mature adipocytes diffusely infiltrating into the skeletal muscle was observed.

Figure 5 A postoperative plane abdominal X-ray examination indicated that the shift of the left colon gas (arrows) was improved as compared to the preoperative state.

Figure 6 Postoperative CT of the abdomen. The encasement of the peritoneal organs was improved as compared to the preoperative state (arrows).
