Extraction Videodermoscopy of Eruptive Vellus Hair Cyst

The article discusses a case of eruptive vellus hair cyst (EVHC), a rare benign condition, in a 24-year-old male, characterized by asymptomatic bluish papules on the forehead and other areas. The study highlights the use of extraction videodermoscopy, a novel diagnostic technique that involves examining a lesion after surgical extraction using a videodermoscope. This method allows for high magnification imaging of the cyst, revealing coiled hair shafts, and potentially eliminates the need for invasive skin biopsies. The findings suggest that extraction videodermoscopy is a simple, effective bedside diagnostic tool for EVHC. Treatment options for EVHC include topical retinoids, urea, and lactic acid creams, as well as surgical excision and laser treatments, though these should be used cautiously due to the risk of scarring.
