A case of nasopalatine duct cyst is described. Such cysts often remain asymptomatic for lengthy periods and may be discovered during routine radiography. The quiescent nature of this cyst underscores the importance of thorough clinical and radiographic examination before the fabrication of a prosthesis, as such cysts may give rise to acute infection, enlargement, and penetration through the overlying mucosa if not removed before denture insertion.
