Renal and cutaneous histopathology

Focused reference notes grouped by tissue compartment and analytical staining technique.

Glomerular architecture

Cutaneous patterns

Ancillary stains

Systematic evaluations of capillary wall integrity, mesangial cellularity, and crescent formation across native and allograft renal biopsies.

Interface dermatitis, dermal infiltrates, and panniculitis breakdowns classified by epidermal reaction patterns and cytologic features.

Diagnostic utility guides for Jones silver, PAS, Masson trichrome, and direct immunofluorescence panels in difficult differential diagnoses.

Diagnostic morphology anchored directly on glass-slide evidence, free from commercial distraction.

Every case analysis pairs standardized histologic criteria with optical micrographs to reinforce reproducible pattern recognition.
