Incidental and unusual renal SOL

Abstract

Introduction: Angiomyolipomas are generally benign and very rare renal tumors. They have two histological subtypes, the triphasic or classic ones, which are usually benign and may or may not be asymptomatic, and the epithelioid type which are associated with tuberous sclerosis disease and whose behavior is more aggressive and malignant. Discussion: We review a case with this pathology, a 56 year old female who presents with left renal LOE of more than 4 cm, completely asymptomatic, so she underwent left radical nephroadrenelectomy, and after taking a sample for biopsy, the histological diagnosis of triphasic angiomyolipoma was made. Conclusion: An imaging study of 6 years before already described LOE in the patient, however, it was smaller in size. These tumors can be complicated by retroperitoneal hemorrhages, which induce hypovolemic shock, and thus a risk to life. The gold standard imaging study for diagnosis is computed tomography.
