An exceptional minute tumour incidentally found in a renal biopsy.

چکیده
Pathological analysis of renal biopsies performed to investigate a nephrological disease may exceptionally reveal incidental tumours, in addition to expected glomerular, tubulointerstitial or vascular pathology. We present the first case to date of a minute angiomyolipoma (AML), found incidentally in a renal biopsy specimen, performed in the assessment of proteinuria. AML is an uncommon kidney tumour, composed of a variable proportion of adipose tissue, spindle and epithelioid smooth muscle cells. Immunohistochemistry is mandatory for a definitive diagnosis, showing a specific perivascular epithelioid differentiation. The diagnosis of renal AML justifies the search for tuberous sclerosis-associated tumours.

متن کاملMultiple Intraosseous Calvarial Hemangiomas Mimicking Metastasis from Renal Cell Carcinoma
Renal cell carcinomas are known to metastasise to the bones in the form of lytic lesions. However, not all osteolytic lesions in patients with renal cell carcinoma are metastatic in nature. The report describes the case of a 68-year old lady who was diagnosed with a renal cell carcinoma 3 and half years back and treated with radical nephrectomy along with excision of an inferior vena cava tumou...
متن کاملIn vivo imaging of cellular proliferation in renal cell carcinoma using 18F-fluorothymidine PET
Objective(s): The ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. The aim of this study was to evaluate the uptake of 18Ffluorothymidine (FLT) PET in renal cell carcinoma (RCC), and to compare this to 18F-fluorodeoxyglucose (FDG), and to an immunohistochemical measure of cellular proliferatio...
