[2 cases of a true splenic cyst].

The nonparasitic cysts of the spleen are uncommon and their pathogenesis has not been precisely determined. Often asymptomatic, the cysts are recognised during an investigation of the abdomen for other pathological conditions; if present, the symptoms are not specific and mild. The authors report two cases of non parasitic cysts of the spleen: in the first case the onset of the disease was insidious, with dyspeptic symptoms and epigastric pain; in the second case, the cyst was initially interpreted like a metastatic localisation of a an abdominal melanoma.
