Process of counselling about and gaining informed consent for procedures, such as skin biopsy under local anaesthetic

Principles

Informed consent for dermatological procedures (skin biopsy, excision, and similar minor procedures, often performed under local anaesthetic) follows standard informed consent principles - explaining the procedure, alternatives, risks/benefits, and confirming understanding before proceeding
Applies to the very high volume of minor procedures performed in dermatology practice, where consent is often less formally documented than for major surgery but the underlying ethical/legal requirement is identical

Even a "minor" procedure carries genuine risks (bleeding, infection, scarring, nerve injury depending on site, and the possibility the histological result changes the management plan) that must be explained regardless of how routine the procedure feels to the clinician performing it

Consent discussion should cover: the procedure itself, the reason it is being performed (including what the biopsy/excision aims to determine or treat), expected recovery, and specific risks relevant to the site and procedure type (e.g. facial biopsy scarring risk, risk of nerve injury at specific anatomical sites)

Local anaesthetic-specific discussion - allergy history, and explaining the sensation the patient will experience (injection discomfort, pressure/pulling sensation during the procedure despite adequate anaesthesia) sets realistic expectations
Document the consent discussion appropriately, matched to the complexity/risk of the specific procedure - a straightforward punch biopsy warrants less extensive documentation than an excision with a significant cosmetic or functional risk (e.g. facial excision near a nerve)

Local anaesthetic allergy/reaction, scarring risk (particularly cosmetically sensitive sites), nerve injury risk (site-specific), incidental findings on histology changing the management plan

Even routine, minor dermatological procedures require genuine informed consent, not just implicit patient cooperation - the "minor" nature of a procedure to the clinician does not reduce the patient's right to understand its risks and alternatives before proceeding
