Pathology Flashcards
Nonneoplastic epithelial disorders of the vulva are
Lichen sclerosus
Lichen cimolex chronicus
Lichen sclerosus
Atrophic epithelium
Subepithelial dermal fibrosis
Bandlike chronic inflammation
Lichen simplex chronicus
Hyperkeratosis
Hyperplasia
Most common congenital kidney diseases
ADPKD
RENAL DYSPLASIA
ADPKD
10% of patients on maintenance renal dialysis
GENE IS PKD1 95%
Kidneys replaced with fluid filled cysts
Diagnoses only during adulthood
Causes renal failure
What’s is the most important complication of ADPKD
Hypertension
Which disease weights as much as 4 kg for each kidney
ADPKD
Cystic renal dysplasia
It’s a developmental abnormality
Can unilateral and bilateral
Kidney has immature nephrons
Cystic dilatations
Unilateral cystic dysplasia
More common then bilateral
Abdominal palpations
Abnormal mass
Non progressive
Non invasive
Replacement of the renal parenchyma with cluster of cysts
Bilateral cystic dysplasia
Associated with urinary tract abnormalities
Renal failure in neonatal period
Both kidneys don’t developed properly in the womb there are bundles of cysts in the kidney
No working kidneys
Most common abdominal mass in infants
1= cystic renal dysplasia
2= wilms tumor
3= neuroblastoma
ARPKD
Present at birth
Renal failure caused by PKHD1 gene
Fibrocystin protein
What is the most common genetic cause of end stage renal diseases in children and young adults
Familial juvenile nephronophthisis
What is the most common cause of chronic kidney disease in humans
Chronic glomerulonephritis
List primary glomerulonephritis
Acute proliferative glomerulonephritis
Rapidly progressive glomerulonephritis
Membranous nephropathy
Minimal change diseases
List secondary glomerulonephritis
Systemic lupus erythamousus
Henoch schonlein purpura
Diabetes mellitus
What are the 2 non exclusive mechanism of the antibody depositions in the glomerulus
1= deposition of circulating antigen antibody complexes
2= antibodies reacting in situ within the glomerulus either with fixed or planted.
Immune couplex + coupleman leads to inflammation
Nephritic syndrome
Immune couplex no couplaman disrupts glomerular permeability
Nephrotic syndrome
Most important glomerular lesions of diabetic nephropathy are
1- capillary basement membrane
2- diffuse mesangial sclerosis
3- nodular glomerulosclerosis
What’s is nodular glomerulosclerosis also known as
Kimmelsteil Wilson disease
List primary glomerular diseases
Minimal change disease
Focal segmental glomerulosclerosis
Membranous nephropathy
IgA nephropathy
Membranoproliferative glomerulonephritis
Secondary glomerular diseases
Systemic lupus erythematosus
Diabetes mellitus
Henoch schonlein purpura
What is the most common cause of nephrotic syndrome in children
Minimal change disease
What is the unique feature for MCD
Absence of glomerular pathology by the light microscopic evaluation
The pathogens is remain unknown
The most cause of nephrotic syndrome in adult
Membranous nephropathy
Pathogenesis of membranous nephropathy
Immune complexes are formed in situ by PLAR2 autoantibodies binding to endogenous podocyte antigens
Or planted antigens
Autoimmune diseases and unknown
Main histoligical finding for MN
Diffused thickening of the GBM
Formation of spikes
No inflammation
Focal segmental glomerulosclerosis pathogenicity
Segmental sclerosis of glomeruli as a primary diseases secondary hiv infection
Obesity
Heroin abuse
Reduced renal mass
Electron microscopy of FSGS
Reveals diffuse foot process effacement
MEMBRANOPROLIFERATIVE GLOMERULONEPHRITIS
Basement membrane thickening
Proliferation of glomerular cells
Caused be immune complex deposition
Trum track splitting of basement
Poststreptococcal glomerulonephritis
Acute glomerular inflammation
Nephritigenic stains of streptococci
Which disease is seen most commonly in children following GAS group A streptococcal tonsillopharyngitis
And skin infections
PSGN
PSGN
Deposition of immmune complex’s within the glomerular basement membrane results in compliment activation and subsequent damage to the glomeruli
Immunfluorescence OF PSGN
Granular staninjng pattern for igG and c3
Electron microscopy of PSGN
Large subepithelial humps of deposited immune complexes
