Nasolabial cyst

Case contributed by Dr Chris O'Donnell

Presentation

Very long standing, painless right anterior nasal mass

Patient Data

Age: 60
Gender: Female
Modality: MRI

Typical location and MRI findings of a benign developmental cyst at the junction of the nose and cheek with minor pressure erosion on bone

Case Discussion

These cysts are rare and on histologic examination show a respiratory epithelial lining of pseudostratified ciliated columnar cells without inflammatory cells.

The origin is a matter of controversy being either retention cysts of mucous glands or fissural cysts due to embryonic nasal epithelium being trapped between the merging maxillary process and the medial and lateral nasal processes.
