- Abstract
Background: Molluscum contagiosum, a skin infection caused by molluscipoxvirus, commonly affects children, sexually active adults and people with immunosuppression. It can be confused with other clinical entities. Recently dermoscopic features of molluscum contagiosum have been described and dermoscopy is a useful, noninvasive and inexpensive tool to determine the diagnosis. Objectives: To evaluate the dermoscopic findings of molluscum contagiosum, to analyze these findings and to relate them with the time evolution of the lesions. Material and method: In a cross-sectional study patients with clinical diagnosis of molluscum contagiosum were evaluated, patients were treated at the Instituto Dermatológico de Jalisco Dr. José Barba Rubio, from December 2011 to January 2012. In each patient the oldest injury, according to the patient, was evaluated; lesion must be at least 3 mm in diameter and should not be treated previously or have dermatitis on itself or outside but adjacent to it. Once the material was obtained, it was evaluated under a microscope and the presence of inclusion bodies Henderson-Paterson was determined, thereby corroborating the diagnosis of molluscum contagiosum. The dermoscopic images were evaluated and described by an expert dermoscopist. Results: We evaluated 40 lesions, which were found most frequently on the trunk (28 [64%]). The mean duration of lesions was 5 ± 4 months (range 0.3 to 18 months). The structures evaluated included nonvascular structures (shooting image, amorphous polylobulated and hole) and vascular structures (vascular ring, irradiated and pinpoint vessels). The most frequently found nonvascular structures were polylobulated structures (21 [53%]), followed by holes and, finally, images of shooting. Septations were also found in an injury. The most frequently found vascular structures were irradiated vessels (18 [45%]), followed by vascular ring and finally pinpoint vessels. Truncated vessels were also found in an injury. Conclusions: In our study dermoscopic findings of molluscum contagiosum were non-vascular and vascular; the most common nonvascular finding was polylobulated structures (53%). The most common vascular finding was the irradiated vessels (45%). There was no statistically significant relationship between time of evolution and the dermoscopic findings of molluscum contagiosum.
