Bilateral congenital oral mucous extravasation cysts

Abstract

This report documents the bilateral presentation of oral mucous extravasation cysts on the left mucobuccal fold and right buccal mucosa of a neonate. The lesions were noted at birth and subsequently enlarged to the point that they interfered with eating. The left lesion ruptured but persisted as an exophytic fibrotic mass. Both lesions were surgically removed at eight months and the diagnosis was confirmed by histopathologic examination. Post-operative follow-up after nine months shows no recurrence. The presentation and diagnostic considerations are discussed.
