Histopathology involves the microscopic study of biopsied or surgically removed tissues.

The report is prepared by a pathologist after examining tissue sections stained with special dyes.

Clinical uses include:

Diagnosing cancers and tumors.

Identifying inflammatory or infectious diseases.

Assessing organ damage or degenerative changes.

Guiding treatment planning and prognosis.

Often requested after biopsy, surgery, or autopsy.

May include gross description, microscopic findings, special stains, immunohistochemistry, and final diagnosis.

Analyte: Tissue morphology and cellular characteristics.

Normal Result: Normal tissue architecture without abnormal cells.

Abnormal Findings:

Neoplastic changes: Benign or malignant tumors.

Inflammatory changes: Acute or chronic inflammation.

Infectious agents: Bacteria, fungi, parasites, or viruses.

Degenerative changes: Fibrosis, necrosis, or organ damage.

Clinical Use:

Provides a definitive diagnosis for tissue pathology.

Helps guide oncology, surgery, and medical management.

Supports prognosis and follow‑up care.
