A 62-year-old woman was referred to our department with repeat asymptomatic swelling at the nasolabial region from 20 years ago. First findings revealed floor of the nose was elevated, hemispherical, fluctuant, without tenderness, and a nasal obstruction which seems to be a protrusion of the nasal floor. (Figure 1) Intra oral findings revealed nothing in particular. Magnetic resonance imaging showed the lesion was approximately 18 mm diameter, well demarcated, homogeneous, and rounded at the nasolabial region. (Figure 2; arrow) The lesion was removed surgically under general anesthesia (Figure 3) and a nasolabial cyst diagnosed pathologically. The patient was doing well after surgery. The protrusion of nasal floor is known as Gerbers protrusion in Germany literatures, which occurs by nasolabial cyst, nasopalatine duct cyst, and radicular cyst at the anterior tooth of maxilla.Figure 1 Figure 2 Figure 3
