title: [Retroperitoneal angiomyolipoma stemming from the psoas. Comments on a case].
abstract: We report a case of subclinical retroperitoneal tumor in a young patient. Although different diagnostic techniques were utilized (US, urography, CT, etc.), the tumor type could not be determined preoperatively. A malignant tumor was suspected, therefore surgical excision was warranted. The pathological analysis disclosed an angiomyolipoma in the psoas muscle, a benign tumor in an uncommon site. The foregoing finding prompted us to report the present case.
