A skin lesion biopsy is a simple outpatient procedure in which a small sample of the patient’s skin is removed and tested in a laboratory. There are several ways the dermatologist can collect a skin sample. A skin biopsy is performed to help determine the cause of a growth, sore or rash.
This could include:
● changing moles
● chronic bacterial or fungal skin infection
● noncancerous growths
● precancerous cells
● skin cancer
● rashes or blistering skin conditions
