A skin biopsy is a minor medical procedure in which a small sample of skin is removed and examined under a microscope to diagnose skin diseases. It is commonly used when a dermatologist needs to identify the exact cause of a skin condition that cannot be diagnosed by visual examination alone.
The procedure is usually done under local anesthesia and is quick and minimally painful. Depending on the condition, different techniques may be used such as punch biopsy, shave biopsy, or excisional biopsy, where a small portion or the entire lesion is removed.
Skin biopsy helps diagnose conditions like skin infections, inflammatory diseases (eczema, psoriasis), autoimmune disorders, and skin cancers. After the procedure, the sample is sent to a laboratory for detailed analysis.
Healing is usually quick, and minor care such as keeping the area clean and protected is recommended. Skin biopsy is a safe and important diagnostic tool for accurate treatment planning.
