[Epidermoid cyst of the spleen. 2 cases].

Two large epidermoid cysts of the spleen have been accidentally discovered in two young men. These cysts are uncommon and represent about 10% of the non parasitic benign cysts of the spleen. From these cases, the authors reviewed the literature. These cysts, which are caused by an abnormal development during the seventh week of the intra-uterine life, are often asymptomatic but the occurrence of a complication may enable the diagnosis. This diagnosis relies on the surgical ablation of the cyst and the histopathologic examination. The surgery should be as conservative as possible.
