Skin biopsy refers to a procedure used by medical professionals to extract a small section of skin tissue for examination and diagnosis of various dermatological conditions. Some synonyms for skin biopsy include skin sampling, skin excision, punch biopsy, and shave biopsy. Skin sampling is commonly used to describe the process in which a small section of skin is removed, while skin excision refers to the complete removal of a skin growth or lesion. A punch biopsy involves using a circular instrument to obtain a cylindrical sample of skin tissue, while a shave biopsy involves using a sharp blade to shave a small section of skin for analysis. All these terms describe the same process of extracting skin tissue for diagnosis.
