Case in brief
A 5-year-old girl presented with swelling of the right upper gingiva. Biopsy at another centre showed an apparent intraosseous cyst lined by stratified squamous epithelium with papillary growth. She was referred for definitive enucleation, but the unusual verrucous proliferation in the cyst lining made the lesion difficult to classify using existing WHO categories for odontogenic cysts. The report describes the cyst’s distinctive lining morphology; the abstract does not state the outcome after enucleation.
What made this case unusual
Verrucous proliferation in an odontogenic cyst lining was exceptionally uncommon in the literature reviewed by the authors, who identified four prior cases.
Diagnostic / clinical pearl
Marked papillary or verrucous growth in an odontogenic cyst lining may not fit established WHO cyst categories; correlate the morphology with the clinical and radiographic context.
