Klestadt's Cyst with Radiographic Contrast Medium: A Case Report.

Klestadt's cyst is commonly known as Nasolabial cyst, is a rare non-odontogenic, soft-tissue, developmental cyst. It accounts for around 0.7% of cysts of the jaws and 2.5% of the nonodontogenic cysts. Following its first description in 1882 by Zukuerkandl, very few cases have been documented in the literature. The cyst usually occurs in the nasolabial region, as a slowly enlarging asymptomatic swelling. As it is a soft tissue cyst, it doesn't show any radiographic changes. Thus contrast medium can be used to visualize the definite extensions. This paper documents a case of nasolabial cyst which was successfully treated in which a radiographic contrast medium was used in order to define the actual extensions of the lesion.
