Biopsy Guidelines

Biopsy Guidelines for Suspicious Pigmented Lesions

Excisional Biopsy (Preferred)

• Excisional biopsy is best practised with a narrow lateral margin >2mm and including superficial subcutaneous tissue.

If Excision Is Not Possible

• If excision is not possible, then take a large incisional biopsy making sure to biopsy through the most atypical pigmented area.

Avoid Partial Biopsies

• Avoid partial biopsies if possible, especially punch biopsies, shave biopsies and curettage in suspicious pigmented lesions.
• For difficult or higher risk biopsy locations, always refer if uncertain.

Referral to WAKMAS

• All melanoma cases requiring sentinel node biopsy should be referred for MDT review at the Western Australian Kirkbride Melanoma Advisory Service.
• WAPSC will on refer to WAKMAS if required.
