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.

Tissue acquisition
Biopsy type, site, fixation, orientation and clinical information affect how much can be inferred from the specimen.
Microscopy
Analyze epithelial and stromal relationships, cellular atypia, inflammation, necrosis and tissue-specific patterns using appropriate stained sections.
Ancillary methods
Immunohistochemistry, special stains and selected molecular tests can refine classification when interpreted alongside morphology and controls.
Report and communication
Document site, method, diagnosis, relevant grade or margin information where appropriate and limitations due to specimen quality or sampling.
