Fivefold enlargement of implants in a splenic autotransplant recipient.

A 30-year-old patient underwent splenectomy for trauma with splenic autotransplantation. Four years later he survived a bout of pneumococcal sepsis with only oral penicillin therapy. Seven years after splenectomy, he underwent another laparotomy with the finding of fivefold enlargement of the splenic implants. Splenic autotransplants enlarge and probably function in human beings.
