Abstract: Background. Accessory spleen represents a small body of splenic tissue that is situated elsewhere in the abdominal cavity than in its normal position, having a congenital origin. Methods. We have investigated 150 forensic autopsies, the purpose of the study being to discover the incidence, distribution, histological aspect and immunohistochemistry features of accessory spleens. Results. Accessory spleens were found in both sexes, 67% were detected at men and 33% at women. In 3 cases the accessory spleen was situated along the splenic hilum and the vascular pedicle of the spleen; in one case the accessory spleen was found around the head of the pancreas; in one case it was found along of the greater curvature of the stomach; and in one case it was situated retroperitoneal, in the perirenal adipose tissue, on the anterior surface. Histological exam revealed normal splenic tissue. The normal spleen and the accessory spleen are presenting myoepithelial cells in the capsule. Conclusions. In all of the research cases, accessory spleens were diagnosed post-mortem and none of it while the person was still alive. Accessory spleens are integrated in the immune response as a functional accessory organ, and also have immunological functions like the normal spleens. We discovered the existence of the myoepithelial cells in the spleen capsule. The proper management in spleen trauma in adults is in debate and the role and myoepithelial cells number need further studies
Keywords: spleen, accessory, autopsy, forensic, immunohistochemistry, myoepithelial cells.
