Abstract
- We report a case of solitary vellus hair cyst on the forehead in a 48 year-old, female patient. She had an asymptomatic, solitary, bluish, 0.3x0.3cm sized papule on the forehead for 1 year. There was no family history of similar lesions. A punch biopsy specimen taken from the papule revealed a cystic structure in the dermis lined by squamous cell epithelium which contained laminated keratinous material and vellus hairs. Based on this histologic finding, we diagnosed this case as solitary vellus hair cyst occurring on the unusual site of the forehead.
