Immunohistochemistry IHC: Tumor Markers, Molecular Surrogates, Diagnostic Panels and Cancer Classification

IHC as Molecular Surrogate in Renal Tumor Diagnosis provides a practical framework for immunohistochemistry, cancer classification, and diagnostic pathology, with attention to specimen quality and interpretation. Diagnostic context includes immunohistochemistry, IHC panel, tumor markers, specimen handling, architecture, cytologic detail, and clinicopathologic correlation specific to this topic. Long-tail searches such as molecular surrogate, cancer classification, and diagnostic pathology are addressed with attention to grading, staging, biomarkers, special stains, immunohistochemistry, or molecular testing when applicable. For pathology case 63, the emphasis remains on reproducible microscopic criteria, differential diagnosis, reporting language, and how tissue findings influence treatment planning. Careful interpretation also requires correlation
