Name of the Procedure:

Tangential biopsy of the skin
Commonly known as shave biopsy, scoop biopsy, saucerize biopsy, or curette biopsy.

Summary

A tangential biopsy involves removing a thin layer of skin from a lesion using a small blade or special instrument. This procedure is minimally invasive and helps in diagnosing various skin conditions, including skin cancer.

Purpose

The tangential biopsy is performed to diagnose abnormal skin growths or lesions. It helps determine if a lesion is benign (non-cancerous) or malignant (cancerous). The goal is to obtain a small tissue sample for microscopic examination.

Indications

• Presence of suspicious moles or growths that may indicate skin cancer.
• Unexplained skin lesions that have changed in appearance.
• Chronic skin sores that do not heal.
• Growths that bleed or cause discomfort.

Preparation

• No specific fasting or medication adjustments are generally required.
• Inform your healthcare provider about any allergies or medications you are taking.
• The area may be cleaned and marked prior to the procedure.

Procedure Description

1. The healthcare provider will cleanse the area around the lesion.
2. A local anesthetic will be injected to numb the area.
3. Using a small blade, scoop, or curette, the provider will carefully shave off a thin layer of the lesion.
4. The tissue sample is then sent to a lab for examination.
5. The site may be treated with a chemical agent to stop any bleeding and a bandage is applied.

Duration

The procedure typically takes about 15 to 30 minutes.

Setting

The tangential biopsy is typically performed in an outpatient clinic or a doctor's office.

Personnel

• Dermatologist or trained healthcare professional performs the procedure.
• Medical assistant or nurse may assist.

Risks and Complications

• Minor bleeding or infection at the biopsy site.
• Scarring or changes in skin color at the biopsy site.
• Pain or discomfort during the procedure (minimal, due to anesthesia).

Benefits

• Provides an accurate diagnosis of skin conditions.
• Quick and minimally invasive.
• Helps in early detection and treatment of skin cancer.

Recovery

• Keep the biopsy site clean and follow care instructions provided by your healthcare provider.
• The site typically heals in days to a couple of weeks.
• Avoid strenuous activities that may impact the biopsy area until healed.
• Follow-up with your healthcare provider as required for results and further treatment.

Alternatives

• Punch biopsy: removes a deeper core of skin tissue.
• Excisional biopsy: involves removing the entire lesion.
• The choice depends on the size, location, and nature of the lesion.

Patient Experience

• Minimal pain during the procedure due to the local anesthetic.
• Mild discomfort or soreness at the biopsy site post-procedure.
• Normal activities can usually be resumed shortly after the procedure, with some care needed to keep the area clean and protected.
