Complications

How do I care for my child’s skin if there are complications?

The risks of a skin biopsy include pain, bleeding, infections, scars and stitches popping open.

Risk	Treatment
Pain	If needed, give your child acetaminophen every four to six hours once or twice after the local anaesthetic wears off. If your child cannot take acetaminophen, ask your doctor for suggestions.
Bleeding	Apply pressure for 15 minutes. Do not peek at the bleeding site while holding pressure.
Infection (rare)	If the area becomes redder or more painful or if there is pus, have it assessed by a local health-care professional. Your child may need oral antibiotics.
Scarring	No treatment is needed. Scarring is normal when the skin heals from a cut.
Stitches popping open	This can happen if the biopsy is done where the skin is tight or if the skin around the biopsy is bumped or stretched. Remove the stitch and clean the skin as instructed.

Follow-up care

When will I find out about my child's biopsy results?

It takes a few weeks to get the results of a biopsy. Your child's health-care team will decide with you when to follow up in the clinic to review the results.
