Splenosis

**Definition:** The spontaneous transplantation of splenic tissue to unusual sites after open splenic trauma, e.g., after automobile accidents, gunshot or stab wounds. The splenic pulp implants appear as red-blue nodules on the peritoneum, omentum, and mesentery, morphologically similar to multifocal pelvic endometriosis.
