Authors report a case of primary retroperitoneal cyst with features of mesothelial differentiation. Review of the international literature revealed rarity of the retroperitoneal cysts showing three similar mesothelial mass only. Primary retroperitoneal cysts, defined as those cysts lying in the retroperitoneal fatty tissue that have no apparent connections with any adult anatomical structure, are liquid mass. They become symptomatic by virtue of their size or position. Diagnosis is suggested by US, TC and MNR. Treatment of choice is radical excision, avoiding marsupialization or incomplete excision cause high risk of local recurrence. Sometimes we have need to apply a multivisceral resection to obtain a complete mass excision, but patient’s performance status has been opportunely considered.
