What is a skin biopsy?
A skin biopsy refers to a procedure for taking a sample of skin for further laboratory evaluation. Skin biopsies are mostly done to help the doctor confirm the diagnosis of a skin rash or lesion. Sometimes, skin biopsies may be done to track the response to treatment. Although skin biopsies are more diagnostic in nature, solitary growths may be completely removed at the same time and treatment affected.
Why do I need a skin biopsy?
A skin biopsy may sometimes be necessary to evaluate the cause of a skin rash. At other times, skin biopsies are used to confirm the type of skin tumour or skin cancer.
Skin biopsies are safe, pain-free and fast procedures. Before the skin biopsy, an anaesthetic injection will be given to allow a painless procedure. A small sample of skin is then obtained either with a punch biopsy equipment or scalpel blade. Sometimes, stitches may be necessary to achieve faster healing after the biopsy. Skin biopsies usually take between 10-20 minutes depending on the size of lesion and number of areas to be biopsied.
How do I prepare for a skin biopsy?
Skin biopsies are fast and simple procedures and no special preparation is needed usually. It will be good to shower and wash your hair before attending a skin biopsy if possible. On the day of the biopsy, take all your medication as usual, unless instructed otherwise.
