ABSTRACT
Objective:To investigate dermoscopic features of molluscum contagiosum.Methods:A total of 82 outpatients with molluscum contagiosum were collected from Dalian Dermatosis Hospital between August 2019 and January 2020, and the dermoscopic features of 227 skin lesions were analyzed retrospectively.Results:Of the 227 skin lesions, hilar depression and orifices were observed in 120 (52.86%) by naked eyes and 198 (87.22%) by dermoscopy, and blood vessels were observed in 20 (8.81%) by naked eyes and 214 (94.27%) by dermoscopy. Different vascular patterns were identified by dermoscopy, including crown-shaped vessels (132 lesions, 58.15%) , punctate vessels (34 lesions, 15.00%) , and a mixed pattern (48 lesions, 21.15%) . The proportion of punctate vessels was significantly higher in lesions with inflammation or exfoliation (86.00%) than in those without (22.03%, χ2=81.685, P < 0.001) , and significantly higher in lesions with eczematous changes (50.00%) than in those without (33.85%, χ2=17.784, P < 0.001) . The most frequently observed structures were round, white-yellow, amorphous structures (40.53%) , followed by four-leaf clover-like pattern (33.48%) , polylobular pattern (20.26%) and nonspecific pattern (5.73%) . Conclusion:Orifices, vascular structures and white-yellow amorphous structures can be observed in molluscum contagiosum by dermoscopy, and the most common vascular pattern is the crown-shaped vessel.
