Flash information
- Technique
- Histology
- Observation
- The stain highlights capillary walls.
- Limitation
- A single image cannot identify a specific antigen.
Definition
A glomerular micrograph identified as membranous nephropathy.
Reading method
Inspect capillary loops and glomerular architecture.
Morphological description
The stain highlights capillary walls.
Interpretation and diagnostic limits
Full interpretation requires several techniques.
Differential diagnoses
Consider other causes of capillary-wall thickening.
Clinical correlation
Integrate immunofluorescence, electron microscopy and proteinuria.
Clinical impact
Clinical risk depends partly on renal function.
Pitfalls
A single image cannot identify a specific antigen.
Take-home message
One stain does not replace the complete biopsy.
