Aggressive Angiomyolipomas: the Clandestine Epithelioid Variant

Curr Urol. 2016 Feb;9(1):54-6. doi: 10.1159/000442853. Epub 2016 Feb 10.

Abstract

Epithelioid angiomyolipoma is a rare mesenchymal derived neoplasm of the kidney. Thought to be a variant of classical angiomyolipoma, a benign tumour, its malignant potential has been highlighted by case reports of loco-regional and distant metastasis. Given the potentially adverse clinical course associated with epithelioid angiomyolipoma compared to classical angiomyolipoma, the distinction and comprehensive histological characterisation of this rare entity is essential.

Keywords: Angiomyolipoma; Computed tomography; Renal cell carcinoma.
