Skin Lesion Assessment and Biopsy
Skin Lesion Assessment and Biopsy provides specialist dermatological evaluation using dermatoscopy and clinical examination, with biopsy when malignancy cannot be excluded -- ensuring early diagnosis of skin cancer when it is most treatable.
Overview
Dermatoscopy increases diagnostic accuracy of melanoma from 60% to 85 to 90% in trained hands. When a lesion cannot be confidently characterised clinically, excisional or punch biopsy provides definitive histological diagnosis. Early detection of melanoma at the in-situ or thin stage is the most important determinant of survival.
Types of Skin Lesion Biopsy
- Excisional Biopsy (complete removal for pigmented lesions and melanoma suspicion)
- Punch Biopsy (cylindrical biopsy for inflammatory conditions)
- Shave Biopsy (superficial biopsy for raised non-pigmented lesions)
- Incisional Biopsy (partial sampling of large lesions)
- Curettage and Cautery (for superficial BCCs and keratoacanthomas)
- Wide Local Excision (definitive treatment for confirmed melanoma)
Common Skin Lesions Requiring Assessment
- Suspected melanoma (ABCDE -- Asymmetry, Border, Colour, Diameter, Evolution)
- Basal Cell Carcinoma (pearly nodule with rolled edge)
- Squamous Cell Carcinoma (rapidly growing keratinising tumour or non-healing ulcer)
- Actinic Keratosis (pre-malignant -- rough scaly patches on sun-exposed skin)
- Seborrhoeic Keratosis (benign -- may mimic melanoma)
- Dermatofibroma, Epidermoid Cyst (benign -- symptomatic lesions)
- Inflammatory conditions requiring histological diagnosis
- Rare cutaneous lymphoma presenting as psoriasiform rash
Features Requiring Urgent 2-Week Assessment
- New or changing pigmented lesion with suspicious dermatoscopic features
- Non-healing ulcer or rapidly growing nodule on sun-exposed skin
- Lesion suspicious for melanoma requiring excision within 2 weeks
- Rapidly growing keratinising lesion on lip, ear, or hand
- Pigmented lesion with blue-white veil on dermatoscopy
- Any lesion in immunosuppressed patient causing diagnostic uncertainty
- Suspicious mucosal pigmented lesion in mouth or genital area
- Nail unit melanoma -- longitudinal melanonychia with Hutchinson's sign
Key Benefits
Discover the advantages of choosing our skin lesion assessment and biopsy services.
Dermatoscopy significantly reduces unnecessary biopsies of benign lesions
Total body skin examination detects asymptomatic skin cancers not identified by the patient
Early melanoma detection at in-situ or thin stage achieves 5-year survival above 98%
Accurate histological diagnosis prevents inadequate excision requiring re-excision
Sentinel node biopsy referral within 2 weeks maximises melanoma staging accuracy
Clinical Features
The technology, techniques and clinical approach behind our skin lesion assessment and biopsy.
Total body skin examination examines all surfaces including scalp soles and genitalia
Dermatoscopy increases melanoma diagnostic accuracy from 60% to 85 to 90%
Standardised photography provides objective baseline for future lesion change monitoring
Excisional biopsy removes the entire suspicious lesion providing the complete histological specimen
Immediate formalin fixation and orientation labelling preserves histological quality
Preparation Instructions
Attend your biopsy result appointment promptly -- histological results guide the urgency of any further treatment. Apply SPF50 sunscreen daily and wear a broad-brimmed hat -- UV protection is the most important long-term skin cancer prevention. Attend annual full skin checks if you have a previous skin cancer. Contact your dermatologist immediately for rapid growth, bleeding, or ulceration of any treated or new lesion.
The Procedure
Step-by-step guide to what you can expect during your skin lesion assessment and biopsy procedure.
Total Body Skin Examination
A systematic head-to-toe total body skin examination is performed examining all skin surfaces including scalp soles between toes and genitalia where skin cancers are frequently missed.
Dermatoscopy of Target Lesions
A dermatoscope providing 10x polarised light magnification is applied to each suspicious lesion. Specific dermoscopic structures guide the malignancy probability assessment with accuracy far exceeding naked eye examination.
Photography and Lesion Documentation
Standardised clinical photographs document all examined lesions for baseline comparison. Total body photography is offered to high-risk patients for future digital follow-up comparison.
Local Anaesthetic Infiltration
1% or 2% lidocaine with adrenaline is infiltrated around the biopsy site. The adrenaline provides haemostasis and prolongs local anaesthesia duration.
Biopsy Technique Selection and Execution
Excisional biopsy removes the entire lesion with 2mm margin for suspected melanoma. Punch biopsy provides a core for inflammatory conditions. Specimen is placed immediately in formalin and labelled with correct orientation.
Histopathology Result Communication
Results are communicated at a dedicated appointment. Confirmed melanoma triggers immediate wide local excision planning and sentinel node biopsy referral within 2 weeks.
What to Expect
Your dermatologist performs a total body skin examination and uses a dermatoscope to examine suspicious lesions in magnified detail. Photographs are taken for the medical record. Biopsies are performed under local anaesthetic in 5 to 15 minutes. Results are available in 7 to 14 working days.
