Several implants of splenic tissue have implanted in the soft tissue of the left upper abdomen. The person had experienced splenic rupture during a car wreck and subsequent surgical removal of the spleen four years before this photo was taken. Macroscopically,<unk>  manifests as individual pieces of reddish-blue tissue with variable shape, which can be as few as one and as many as 300, mostly in the abdominal cavity, and varying in size from a few millimeters to as large as 12 cm. Due to the limited blood supply to these nodules, the typical size of splenic implants is usually less than 3 cm. The implants can be separate pieces or connect to other pieces of splenic tissue by a thin stem. Histologically, the regular spleen tissue is made up of red and white pulp, similar to the structure of an accessory spleen.
