Surgical approach to benign small papular and dome‐shaped melanocytic naevi on the face

Abstract

Patients frequently request removal of benign papular and dome-shaped naevi for cosmetic or functional reasons. Melanocytic naevi can be removed by elliptical, round, punch or shave excision or destroyed using electrodessication or cryotherapy. Total elliptical excision is probably the most widely used method of removal. If malignancy is suspected, adequate specimens for histological interpretation are required. When malignancy is not suspected, the cosmetic result becomes the first priority. Smaller incisions minimize tissue trauma and so give cosmetically superior results. Round excision has been recommended for the removal of moles but has not been widely practised. Round excision and punch excision may be better alternatives than conventional fusiform excision of benign dome-shaped or papular naevi of the face, as more tissue is preserved. Shave excision of naevi may be preferable to elliptical excision in sites where the incidence of hypertrophic scarring is high, as preservation of some thickness of the dermis may result in a more acceptable scar or even avoid a scar entirely. Expedient and simple surgery with excellent cosmetic results can be accomplished by the use of punches. Cryotherapy with cutting or curetting and electrodesiccation combined with shaving have been described. Round excision may be a better alternative to conventional fusiform or shave excision of benign papular or dome-shape nevus of the face because it leaves an almost imperceptible scar. In this technique, less skin is excised and histopathological examination can be done.
