“…Grey-scale ultrasound exhibited an extremely poor diagnostic accuracy (21%) for angiomyolipomas, though the combination of gray-scale and power Doppler ultrasound increased the diagnostic accuracy. Despite the fact that fat-poor angiomyolipomas contain no macroscopic focus of fat by ultrasound or CT scans, these tumors histologically contain an average of 4.1% fat [40]. …”

Although not as common as other genetic renal diseases such as autosomal dominant polycystic kidney disease, patients with tuberous sclerosis complex frequently have significant renal involvement. Recent revelations in the cell biology of these renal disease manifestations as well as effective therapies for tuberous sclerosis complex-related renal issues have heralded hope of improved renal survival and improved quality of life for the TSC patient. This review specifically addresses some of the major renal manifestations of this disease.

“…Therefore, most patients with minimal fat AML are confirmed by pathological examination postoperatively. 12 Recently studies 13 showed that immunohistochemical analysis with HMB-45 is useful in differentiating between AML and other neoplasm of the kidney. Our immunohistochemical results revealed that positive of HMB-45 are present both in renal mass and in lymph nodes.…”

E568Cite as: Can Urol Assoc J 2015;9(7-8):E568-71. http://dx.doi.org/10.5489/cuaj.2749 Published online August 10, 2015. AbstractRenal angiomyolipomas (AML), consisting of fatty tissue, blood vessels, and smooth muscular cells in various proportions, is a relatively common benign renal neoplasm. Simultaneous involvement of the kidney and lymph nodes is uncommon and might be confused with an advanced renal cancer. AML is divided into minimal fat AML and fat-predominant AML. However, minimal fat AML with lymph node involvement is extremely rare and difficult to differentiate from RCC on images. We report such a case and review the literature.

“…With an average of 3 cm in diameter, hyperattenuating AMLs are naturally small [9,10] . On CT, they are diagnosed by identifying a portion of the mass with an attenuation of 45 HU or more which is indicative of smooth muscle [2] .…”

“…On CT, they are diagnosed by identifying a portion of the mass with an attenuation of 45 HU or more which is indicative of smooth muscle [2] . At pathology, these AML consist mostly of smooth muscle components and scanty to no amount of fat cells, with the tumor cells staining positively for HMB-45 [10] .…”
