Splenosis is the result of spleen tissue breaking off the main organ and implanting at another site inside the body. This is called heterotopic autotransplantation of the spleen. It most commonly occurs as a result of traumatic splenic rupture or abdominal surgery. Depending on the location of the spleen, the new piece usually implants in another part of the abdominal cavity (including the pelvic cavity). Single case reports also describe splenosis in the thoracic cavity, in subcutaneous tissue, in the liver or in the cranial cavity. Splenosis must be distinguished from the presence of additio

Splenosis is the result of spleen tissue breaking off the main organ and implanting at another site inside the body. This is called heterotopic autotransplantation of the spleen. It most commonly occurs as a result of traumatic splenic rupture or abdominal surgery. Depending on the location of the spleen, the new piece usually implants in another part of the abdominal cavity (including the pelvic cavity). Single case reports also describe splenosis in the thoracic cavity, in subcutaneous tissue, in the liver or in the cranial cavity. Splenosis must be distinguished from the presence of additional spleens, which are innate and are the result of differences in embryological development. Additionally, splenosis must be differentiated from malignant tumors which may look similar when imaged.
== History == Ectopic splenic tissue was first described in 1896 by Albrecht in Germany, whereas the term "splenosis" was first used by Buchbinder and Lipkoffin to describe their findings in 1939.
