title: Glabellar pomade crust mimicking dyskeratosis follicularis.
abstract: A 79-year-old female patient presented with a slowly developing crusting, itching verrucous lesion of the forehead of 3 months' duration. She had no personal or family history of skin disease. On examination she presented with a hyperpigmented plaque of the glabellar region that resembled dyskeratosis follicularis Darier. A detailed medical history was taken and a skin biopsy was performed. Epidermal acanthosis and enlargement of follicle ostia with foreign material were found. The patient reported use of an ointment twice daily. She had a single cosmetic treatment where powder of unspecified composition had been used. The diagnosis of pomade crust was confirmed. Follicular material was enucleated mechanically and the area was treated with a metronidazole cream. The lesions completely disappeared.
