• Resumen

  • Angiomyolipomas (AML) are mesenchymal tumors belonging to the group of perivascular epithelioid cell tumors, which, rarely, can display a malignant behavior. They are composed of adipose tissue, vessels, and muscle tissue in different proportions, and constitute a differential diagnosis for other focal liver lesions. We report a 34-year-old woman in whom a focal hepatic lesion was discovered incidentally. The pathology report of an ultrasound guided biopsy informed an epithelioid angiomyolipoma, a rare variant of these lesions. During ten years of imaging follow, the size and features of the lesion has not changed. The patient rejected a surgical excision.
