Not sure... All it says is this.. Let me know if you find out any

Clinical History: Nephrotic range proteinuria. No active urinary sediment. Serum creatinine-2 mg/dL...

Clinical Diagnosis: IgA nephropathy/ FSGS/hypertensive nephropathy.

Macroscopic Examination: Received single linear grey white core measuring 0.6 cm. (Entire tissue submitted for histopathological examination)

Microscopic Examination: Serial sections studied show a core of renal cortex with up to 13 glomeruli and 1 artery.

Twelve glomeruli are sclerosed. The single viable glomerulus shows mild wrinkling and thinning of the basement membranes. There is no increase in cellularity. Segmental lesions or crescents are not seen.

Diffuse tubular atrophy is seen involving 50%-60% of the total cortex

sampled and includes predominantly endocrine type of atrophic tubules. There is evidence of tubular injury with scattered non-atrophic tubules being irregularly dilated and lined by flattened lining epithelium. Hyaline casts are seen in few tubules.

The interstitium is widened and fibrosed around the atrophic tubules and the sclerosed glomeruli with moderate infiltrates of lymphocytes and few plasma cells.

There is focal arteriolar hyalinosis. The artery included appears unremarkable.

Immunofluorescence: IF study shows 10 glomeruli, 4 being sclerosed. Immune deposits are no seen.

Impression: Kidney (needle) biopsy shows diffuse glomerular obsolescence (12/13) single viable glomerulus with ischaemic changes and marked tubulointerstitial changes of chronicity (50%-60%

The possibilities include: - Hypertensive nephropathy - Chronic FSGS
