ABSTRACT
OBJECTIVE:
Renal angiomyolipoma is a mesenchymal neoplasm composed of dysmorphic blood vessels, smooth muscle, and adipose tissue. Epithelioidangiomyolipoma is an uncommon variant considered potentially malignant. We report a case of renal epithelioid angiomyolipoma suspicious for urothelialcarcinoma of renal pelvis.METHODS:
A 50-year-old woman with a 3-day history of macroscopic hematuria and CT-scan showing a tumor arising from the left renal pelvis suspicious for urothelialcarcinoma. Nephrectomy was analysed in multiple slides of hematoxilin-eosin and immunohistochemistry.RESULTS:
Left nephrectomy was performed. Tumor sized 8 cm and showed pathologic findings of epithelioid angiomyolipoma with a little component of classic angiomyolipoma. We studied differential diagnosis and pathologic characteristics for the prognosis.CONCLUSIONS:
Pathologic study in detail is fundamental for differential diagnosis and prognosis of this tumor. Our patient's pathology showed good prognosis, however follow-up is important due the malignant potential of the neoplasm.
