[True splenic cysts. Two clinical cases].

Two case reports of epidermoid cyst of the spleen are presented. Only 700 cases have been reported so far. Although splenic cysts are benign lesions and could involve spontaneously, the risk of rupture of a large cyst is high, so a diameter of 5 cm was suggested as the higher limit for nonsurgical treatment. For many years the surgical treatment of splenic epidermoid cysts was splenectomy: however recognition of the short and long-term complications of radical splenectomy had led to the practice of splenic preservation (partial splenectomy, total cystectomy, laparoscopic cyst decapsulation).
