A punch biopsy is a simple in-office procedure used to diagnose a wide range of skin conditions. During the procedure, Dr. Dina Strachan removes a small, circular sample of skin using a specialized instrument called a punch. The tissue is then sent to a laboratory where a dermatopathologist examines it under a microscope.
Why Is a Punch Biopsy Performed?
Many skin conditions can look similar on the surface. A punch biopsy allows Dr. Strachan to look beneath the skin and confirm a diagnosis when a visual examination alone is not enough.
A punch biopsy may be recommended to evaluate:
- Rashes that have not responded to treatment
- Inflammatory skin conditions such as psoriasis or eczema
- Autoimmune skin disorders
- Certain skin infections
- Hair loss conditions affecting the scalp
- Possible skin cancers
What to Expect During the Procedure
A punch biopsy is typically completed in just a few minutes. After cleansing the area, Dr. Strachan administers a local anesthetic to keep you comfortable. A small circular instrument is then used to remove a sample of skin.
Depending on the size of the biopsy, the site may be closed with one or two stitches. A bandage is applied, and you will receive instructions on how to care for the area while it heals.
Will There Be a Scar?
Any procedure that removes skin can leave a small scar. However, punch biopsies are designed to obtain the information needed while minimizing cosmetic impact whenever possible. Dr. Strachan carefully selects the biopsy location and closure technique to help achieve the best healing outcome.
Getting Your Results
Biopsy results are typically available within one to two weeks. Once the pathology report is received, Dr. Strachan will review the findings with you and discuss any next steps, including treatment recommendations if necessary.
