Clinical and histopathological analysis of 790 naevi excised from 509 patients due to cosmetic reasons

Abstract

Background The risk of malignant transformation is the most important reason for melanocytic naevi excision whereas the most common reason for excision is cosmetic disturbance.Methods Our study was conducted in a retrospective design from June 2009 to October 2013 involving 790 naevi excisions from 509 patients (332 male, 177 female) due to cosmetic disturbance. Each patient was evaluated for age and gender in addition to the clinical characteristics of the lesions such as location, size, depth and morphology. Results The average age of our patient group was 36.4 (18-68). Of the 509 patients, 332 were female (65.2 %) and 177 were male (34.7%). Intradermal naevus was the most common type. Of all patients, 93.3% had intradermal, dysplastic or compound naevi. Of all lesions, 93.9 % were intradermal, dysplastic or compound naevi. Buccal region was the most common excision site in the face with 112 excisions. Female gender was dominant in all naevi types except for dysplastic naevi and junctional naevi. Male gender was dominant in these groups.Conclusions Gender and age in addition to the clinical characteristics of the lesion such as location, size, depth and morphology were analysed for each patient. To our knowledge, our study has the largest naevi excision number performed for only cosmetic reasons. Even though there was no malignant melanoma identified, high rate of dysplastic naevi was an important data due to its malignancy risk.
