Eruptive Vellus Hair Cysts of the Labia Majora: Detection of Openings of the Cysts to the Epidermis by Dermoscopy

The document discussed eruptive vellus hair cysts (EVHC), which were characterized by multiple, asymptomatic, small, skin-colored or yellowish papules with a smooth or centrally umbilicated surface, typically found on the chest or upper extremities. The study focused on a case involving the labia majora and utilized dermoscopy to detect openings of the cysts to the epidermis. This method provided a non-invasive way to observe the cysts' characteristics and confirmed their presence and structure.
