| disease | |
| benign tumor of the kidney thought to arise from intercalated cells. will result in large eosinophilic cells with a central stellate scar | |
| benign renal tumor composed of vascular, fat and sm. muscle tissue. grow rapidly during pregnancy. triphasic histology | |
| cancer arising from the renal tubular epithelium. risk factor: smoking. clear cell types come from proximal tubule epithelium. most are not detected before metastasis. presents wit | |
| cancer of transitional cells in the urinary tract. presents with gross hematuria | |
| can progress to pyelonephritis. can be caused by drugs, infections, etc. presents with urinary frequency, suprapubic pain, dysuria | |
| kidney stones composed of calcium and phosphate. more common in males. | |
| rapid loss of renal function. crescentic glomeruli, nephritic syndrome, can be caused by antibodies to GBM or immune complex deposition | |
| autoimmune reaction to type iv collagen in the GBM. results in RPGN. effects kidneys and lungs. EMs will not reveal Abs but IF will reveal smooth deposition pattern | |
| most common RPGN. granulomas are found in the lungs, C-ANCA test is used to IF and EM will be negative for antibodies in the GBM. skin rash can also occur | |
| strep infection results in antibody deposition in the GBM little humps on the epithelial side of GBM will be seen | |
| proteinuria, RBC casts, hematuria, hypertension, hypoalbuminemia. inflammation of the glomeruli. usually acute | |
| causes glomerulonephritis with lumpy bumpy immunofluorescent staining | |
| massive proteinuria and hypoalbuminemia, no hematuria, hyperlipidemia | |
| caused by antibodies to podocyte anitgens. sometimes involve immune complex deposition due to infection, drugs, lupus. little to no inflammatory infiltrate. thickening of GBM | |
| fusion of podocyte foot processes. seen in children, presents as nephrotic syndrome. histologically normal, response well to steroids (autoimmune?) | |
| nephrotic syndrome secondary to heroin addiction, AIDS, etc. most common nephrotic syndrome of adults. not responsive to steroids. some glomeruli affected, | |
| glycosylation of GBM components. starts as microalbuminemia. thickening of GBM. nodular version with Kimmelstein-Wilson bodies is also seen | |
| hypersecretion of IgA results in deposition in glomerulus. can present with Henoch-Schoenlein purpura | |
| can result from UTI progression. presents with pus in the tubules, fever, dysuria, frequency | |
| rapid decline in kidney function (hours/days) | |
| caused by ischemia in the kidney. dark brown casts result in the urine. most common cause of acute renal failure | |
