What Are Skin Biopsies?

Skin biopsies are diagnostic procedures that involve removing small samples of skin for microscopic examination. They help identify conditions such as melanoma, psoriasis, eczema, or fungal infections. Types of biopsies include:

Shave Biopsy: For raised or superficial lesions.
Punch Biopsy: For deeper or inflamed skin conditions.
Excisional Biopsy: For complete removal of suspicious growths.
Incisional Biopsy: For partial sampling of large or complex lesions.

Our dermatologists choose the method based on lesion type, size, depth, and location to ensure accurate results with minimal tissue disruption.

Biopsy Techniques & Their Applications

Shave Biopsy

Mechanism: Surgical blade removes the lesion’s raised portion.
Best For: Seborrheic keratoses, superficial basal cell carcinomas, benign moles.
Protocol: 5-minute procedure, no stitches; heals in 1–2 weeks.

Punch Biopsy

Mechanism: Circular tool extracts a full-thickness skin sample.
Best For: Rashes (eczema, psoriasis), deeper skin infections, autoimmune conditions.
Protocol: Typically 1–2 sutures; results in 7–10 days.

Excisional Biopsy

Mechanism: Scalpel removes the entire lesion with margins.
Best For: Suspected melanomas, cysts, larger tumors.
Protocol: 15–30 minutes; sutures removed in 7–14 days.

Incisional Biopsy

Mechanism: Removes a portion of large lesions.
Best For: Complex ulcers, plaques, or lesions in sensitive areas.
Protocol: Sampled tissue only; minimal disruption to healthy tissue.

When Is a Skin Biopsy Recommended?

A biopsy may be advised if you experience:

Suspicious Moles: Asymmetry, irregular borders, colour changes, or rapid growth.
Chronic Rashes: Persistent skin irritation unresponsive to treatment.
Non-Healing Wounds: Ulcers or sores lasting more than four weeks.
Monitoring Needs: To track or confirm chronic inflammatory conditions.

Who Should Consider a Biopsy?

Patients with atypical moles or changing lesions
Individuals with persistent or recurrent rashes
Immunocompromised patients at higher risk for skin infections or malignancies

Procedure Timeline & Recovery

Shave/Punch Biopsy: Completed in one session; mild discomfort. Keep area dry for 24 hours.
Excisional Biopsy: May require minor suturing. Avoid strenuous activities for 48 hours.
Follow-Up: Results typically ready in 7–14 days.

Safety & Aftercare

Our dermatologists follow strict hygiene protocols and personalize aftercare instructions based on your biopsy type and skin condition:

Infection Risk: <1% with proper care; antibiotic ointment recommended.
Scarring: Typically minimal; silicone gel may improve healing.
Bleeding: Rare; gentle pressure can stop mild oozing.
General Care: Avoid sun exposure, scratching, or submerging the wound during healing.
