Introduction:
Blood cells are mainly destroyed in the spleen during autoimmune cytopenia. Amongst the various therapeutic strategies, splenectomy is sometimes necessary during the disease course. However, splenosis or accessory spleens can account for autoimmune cytopenia relapse after initial splenectomy in these patients.
Case Report:
We report an 18-year-old male with common variable immunodeficiency who presented with immunological thrombocytopenia. Splenectomy allowed remission of cytopenia, but a relapse was attributed to splenosis, because Jolly bodies were absent on blood smear. Laparoscopic splenectomy of accessory spleens induced long term remission. A literature review is performed.
Conclusion:
Fifteen to 20% of relapses of autoimmune cytopenia treated by splenectomy are related to accessory spleens. Ablation of accessory spleens can cure again the patients, including patients with accompanying common variable immunodeficiency.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
