Clinical Mechanism & Overview
Skin biopsy is a small diagnostic procedure where a tiny sample of skin is collected and sent for laboratory analysis. It helps confirm conditions that cannot be diagnosed confidently by examination alone, including persistent rashes, suspicious growths, pigment disorders, and chronic inflammatory skin diseases.
Types Of Skin Biopsy
Different approaches may be selected depending on your skin concern, treatment goal, and dermatologist assessment.
Punch Biopsy: A small circular sample is taken for diagnosis of selected skin conditions.
Shave Biopsy: A superficial sample may be selected for certain raised benign-looking lesions.
Excision Biopsy: A small lesion may be removed fully when complete assessment is required.
