We present a 76-year-old patient with multiple renal angiomylipoma in one kidney. The patient had not been having any urinary tract symptoms, the lesions in kidney were visualized in US examination performed because of cholelithiasis suspicion. Angiomyolipoma is included to the benign tumors of hamartoma group and its growth is related to the hormonal activity of the organism. Multiple renal an...

BACKGROUND Angiomyolipoma is a benign mesenchymal tumor composed of variable amounts of smooth muscle, adipose tissue and thick-walled blood vessels, and usually named PEComas (perivascular epithelioid cell tumors). PEComas share overlapping histopathological features with epithelioid cells along a perivascular distribution and characteristic immunohistochemistry with coexpression of myoid and ...

INTRODUCTION The World Health Organization defines epithelioid angiomyolipoma as a potentially malignant mesenchymal neoplasm characterized by proliferation of predominantly epithelioid cells and as closely related to the triphasic (classic) angiomyolipoma. It can be benign, potentially aggressive or malignant. The pathologist's role is crucial in making a positive diagnosis, providing appropri...

OBJECTIVE To evaluate the clinical effect of renal artery embolization with a mixture of lipiodol and polyvinyl alcohol (PVA) particles on symptomatic renal angiomyolipoma and to present the mid-term results from our single-center site. METHODS We performed a retrospective review of the seven patients who underwent embolization with a mixture of lipiodol and PVA particles to treat symptomatic...
