Splenosis involves the autotransplantation of splenic tissue. The number and distribution of the splenic tissue deposits depends on the precipitating event.
Deposits may be pink, red, bluish-red or black.
The number of deposits may range from one to numerous.
Usual location(s) of splenic tissue:
(1) serosal surface of small or large bowel
(2) mesentery to small or large bowel
(3) greater omentum
(4) parietal peritoneum
(5) inferior surface of the diaphragm
(6) on or within the liver
Unusual location(s) for deposits:
(12) lesser omentum
(13) urinary bladder
(14) uterus or adnexal structures in a female
(15) subcutaneous tissue
If there is a defect in the diaphragm at the time of splenic rupture, then deposits may be located in the left thorax (on the visceral or parietal pleura, in the left lung).
