Diagnostic histopathology

Diagnostic histopathology interprets tissue architecture, cellular morphology and lesion distribution in clinical context. A biopsy is a sample that may not represent the entire lesion.

Original schematic relationship map for this topic; relationships are organized for study, not intended as an anatomical depiction or a diagnostic algorithm.

Concept 01

Tissue acquisition

Biopsy type, site, fixation, orientation and clinical information affect how much can be inferred from the specimen.

Concept 02

Microscopy

Analyze epithelial and stromal relationships, cellular atypia, inflammation, necrosis and tissue-specific patterns using appropriate stained sections.

Concept 03

Ancillary methods

Immunohistochemistry, special stains and selected molecular tests can refine classification when interpreted alongside morphology and controls.

Concept 04

Report and communication

Document site, method, diagnosis, relevant grade or margin information where appropriate and limitations due to specimen quality or sampling.

Education / safety note: An image of a generic lesion is not a histologic diagnosis. Sampling, staining and observer variation require quality assurance.
