ROJO ALVARO, J. et al. Splenic disorders in internal medicines. Anales Sis San Navarra [online]. 2014, vol.37, n.1, pp.169-176. ISSN 1137-6627.  https://dx.doi.org/10.4321/S1137-66272014000100022.

The spleen is the largest lymphopoietic organ, containing 25% of total lymphoid mass. It participates in cellular and humoral immunity and intervenes in the renovation of red cells and the elimination of bacteria. Splenic functions are reduced when the spleen is absent, which entails, amongst other complications, greater susceptibility to suffering from sepsis due to encapsulated organisms. We present 6 clinical cases admitted to the Internal Medicine serve with splenic pathology and we make a review of the approach to be used. The spectrum of splenic lesions in internal medicine is very wide. On occasions, a splenic pathology can be suspected due to clinical history, physical exploration or because of cytopenias in the analyses. Different complementary tests are available for completing study of these lesions. A splenectomy can be carried out in case of diagnostic doubt, with the most frequent diagnoses being hepatic cirrhosis and lymphoma/leukaemia.
