SKIN BIOPSIES
Skin biopsies are a critical tool in the diagnosis of skin lesions. Rashes, moles, and skin cancers have a variety of presentations and forms.
Often the diagnosis is obvious to a Board Certified Dermatologist, but sometimes a skin biopsy is required for diagnosis or staging.

SKIN BIOPSIES IN DEPTH
by Martin Kassir, M.D., F.A.A.D.
The different types of skin biopsies available are:
- Shave biopsy
- Punch biopsy
- Excisional Biopsy
How is a skin biopsy performed?
- The area is properly cleaned
- The area is anesthetized with a small injection.
- The skin sample is obtained, placed in a container, and sent to a Dermatopathologist for evaluation.
- The area is then dressed, and the patient takes care of the area at home usually with antibiotic ointment and adhesive bandages.
Depending on the type of skin biopsy, you may or may not have one or more sutures.
The lab report is usually back in just a few days. Depending on the diagnosis, further action may be necessary (example: a skin cancer may need to be fully excised)
aSKINg the EXPERT: Skin Biopsies
"When and why do I need a skin biopsy?"
A TBSE (Total Body Skin Exam) is recommended annually to identify suspicious lesions early on that may require a biopsy.
If you have lesions that change in size, shape, color, or elevation (height), or ones that have irregular borders, they should be evaluated by your dermatologist. A biopsy may be necessary for microscopic tissue identification by a dermapathologist.
