title: Congenital sinus of the upper lip with idiopathic precocious puberty.
abstract: An extremely rare case of congenital sinus of the upper lip is presented in a 22-year-old woman with idiopathic precocious puberty. The sinus has a pin-like orifice located in the midline of the upper lip philtum just below the base of the columella. Sexual precocity was found out when she was 7 years old. A series of exact examinations had been performed at that time. Neither neurogenic lesions of the central nervous system nor other systemic abnormalities were observed. Oral Diseases
