TLDR Eruptive vellus hair cysts are often underreported and need histologic confirmation for accurate diagnosis.
The document discussed a case of a 6-year-old Caucasian girl with numerous asymptomatic, flesh-colored eruptive vellus hair cysts on her buttocks, thighs, and groin, which increased over three months. Histological examination showed keratin-filled cysts in the upper middermis with vellus hair. The study highlighted the importance of distinguishing these cysts from other epithelial cysts with hair shafts through histological analysis. It suggested that eruptive vellus hair cysts were likely underreported due to their lack of symptoms, emphasizing the need for histologic confirmation to ensure accurate diagnosis and differentiation from other conditions.
