Abstract
|
|
|
Congenital double lip is a rare congenital anomaly of lip characterized by transverse furrow between 2 vermilion borders and hypertrophies of labial glands in buccal portion of the double lip.
In etiology and teratogenesis of this anomaly, transverse furrow dividing the double lip represents as an exaggerated boundary line between pars glabra and pars villosa, and also represents a hypertrophy of pars villosa in the buccal portion of the double lip.
Recently authors have experienced a case of congenital double lip and was corrected with 2 elliptical excision for preservation of frenulum.
On microscopic examination, the buccal portion of double lip consists of normal appearanced mucosal layer with overlying prominant hyperplastic mucous glands scattered in a normal dermal layer and there are no evidence of inflammation and muscle fiber in buccal portion.
