The punch tool is a swift and practical instrument in the facial pigmented melanocytic nevus. However, few studies have evaluated the efficacy of the method for facial pigmented nevus. The aim of this study was to evaluate the practicability and effectiveness of removing facial pigmented nevus by punch biopsy technique. This was an observational study of patients with facial pigmented nevus in the Hospital of Plastic Surgery, Weifang Medical University. The ages of patients ranged from 15 to 36 years (average, 25 y). The outcome evaluations included Vancouver Scar Scale (VSS) score, esthetic appearance, and patient satisfaction. Following standard procedures, preoperative surgical excision was performed with safety margins. Anatomopathologic analysis of the surgical specimen was used as the gold standard to evaluate the accuracy of diagnosis by punch biopsy. From January 2019 to January 2020, this punch technique was carried out on 96 patients (151 pigmented nevus) with 35 melanocytic nevus on the forehead, 39 on the cheek, 21 on the eyelid, and 45 on the nose, whereas 11 were on nasolabial folds. The diameters of pigmented nevus are 0.5 to 10 mm on the face. All patients were evaluated at a follow-up visit ranging from 6 to 20 months (average, 11 ± 1.5 mo) and healed with no complication. The histopathological examinations of the skin lesions showed benign outcomes. The mean Vancouver Scar Scale were 1.1 ± 0.4. Ideal cosmetic and functional outcomes were achieved in 94 patients (97.9%). All patients achieved complete satisfaction except 2 patients with partial satisfaction. No recurrences and complications were recorded. This study demonstrated that the punch technique is an ef-fective method to remove facial pigmented melanocytic nevus with acceptable functional and esthetic outcomes without relapse.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
