A skin biopsy involves removing a small sample of skin so that it can be evaluated by a pathologist.

This allows for:

• Accurate diagnosis of skin conditions
• Differentiation between benign and concerning lesions
• Guidance for appropriate treatment

Biopsies are commonly performed when a diagnosis is uncertain or when confirmation is needed before proceeding with treatment.

A biopsy may be recommended for a variety of reasons.

Common indications include:

• Evaluation of a suspicious mole or lesion
• Diagnosis of a persistent rash
• Assessment of unusual growths
• Confirmation of skin cancer or precancerous changes
• Clarification of inflammatory or autoimmune skin conditions

The decision to perform a biopsy is based on clinical judgment and the need for diagnostic clarity.

Shave Biopsy

A shave biopsy involves removing a thin layer from the surface of the skin.

It is commonly used for:

• Superficial lesions
• Raised growths
• Certain types of moles

This technique is quick and typically does not require sutures.

Punch Biopsy

A punch biopsy uses a small, circular instrument to remove a deeper sample of skin.

It is often used for:

• Rashes or inflammatory conditions
• Lesions requiring full-thickness evaluation

Depending on the size, sutures may be placed to close the site.

Excisional Biopsy

An excisional biopsy involves removing an entire lesion, often with a margin of surrounding skin.

It is typically used for:

• Suspicious moles
• Lesions where complete removal is appropriate

This method provides the most comprehensive sample for evaluation.

Skin biopsies are performed in the office under local anesthesia.

During the procedure:

• The area is numbed to ensure comfort
• A small sample of skin is removed using the appropriate technique
• The site is treated and, if necessary, sutured

The procedure is typically brief and well tolerated. Patients are able to resume most normal activities immediately afterward.

After the biopsy, the tissue sample is sent to a specialized dermatopathology laboratory. A pathologist examines the sample under a microscope to determine the diagnosis.

Results are typically available within several days, and patients are contacted to review findings and next steps.

Recovery is generally straightforward.

Patients may experience:

• Mild tenderness or soreness at the site
• A small wound that heals over one to two weeks
• Temporary scabbing or redness

If sutures are placed, they are usually removed within one to two weeks, depending on the location.

Detailed aftercare instructions are provided to support healing and minimize scarring.

Any skin procedure can result in a small scar, but efforts are made to minimize its appearance.

Factors that influence healing include:

• Location on the body
• Size and depth of the biopsy
• Individual healing characteristics

At Treiber Dermatology, biopsies are performed with careful technique to optimize cosmetic outcomes whenever possible.

Once results are available, they are reviewed and discussed with the patient.

Based on the findings, next steps may include:

• No further treatment if the lesion is benign
• Additional treatment or removal if needed
• Ongoing monitoring

Clear communication ensures that patients understand their diagnosis and plan.

A biopsy may be recommended for patients who:

• Have a suspicious or changing lesion
• Have a persistent or unexplained rash
• Require confirmation of a diagnosis
• Need evaluation prior to treatment
