What is the primary purpose of a skin biopsy?

The primary purpose of a skin biopsy is to determine the presence of disease. This procedure involves the removal of a small sample of skin for examination under a microscope. A pathologist analyzes the tissue to identify any abnormalities, such as cancer, infections, inflammatory conditions, or other skin disorders. By providing definitive information about the nature of a skin lesion, a biopsy plays a crucial role in diagnosis, guiding treatment options, and monitoring disease progression. It is a vital tool in dermatology for accurately assessing various skin conditions and ensuring appropriate patient management.
