Punch Biopsy

Punch Biopsy (Derma)

Once the specimen is obtained, caution must be used in handling it to avoid crush artifact. Punch biopsies are useful in the work-up of cutaneous neoplasms, pigmented lesions, inflammatory lesions and chronic skin disorders. Properly administered local anesthesia usually makes this a painless procedure. Skin biopsy is the most important diagnostic test for skin disorders. In selected patients, a properly performed skin biopsy almost always yields useful diagnostic information. Some authors believe that most errors in dermatologic diagnosis occur because of failure to perform a prompt skin biopsy.
