A skin biopsy is a common procedure in dermatology and is performed for diagnostic purpose. If skin cancer is suspected a tissue sample (Biopsy) must be examined microscopically to confirm the diagnosis. When the diagnosis is confirmed, different treatment options will be provided by the Doctor.
Shave Biopsy. Under a local anesthetic, the doctor uses a scalpel to remove a small amount of skin in order to provide tissue for pathology diagnosis.
Punch Biopsy. This procedure is performed under a local anesthetic and involves cutting into the top layer of fat beneath the skin. A punch biopsy is deeper than a shave biopsy, which may allow for the entire lesion to be removed requiring sutures.
A skin biopsy is performed to diagnose:
- Bacterial or fungal skin infection
- Skin disease
- Skin cancer
