Novel intraoral phenotypes in hyperimmunoglobulin-E syndrome.
OBJECTIVE
Hyperimmunoglobulin-E syndrome (HIES) is a primary immunodeficiency characterized by eczema, recurrent skin and lung infections with pneumatocoele formation, and extremely elevated serum immunoglobulin-E. The precise immunologic defect and genetic etiology remain unknown. Non-immunologic findings include characteristic facial features (prominent forehead, fleshy nasal tip, and increased interalar distance); skeletal involvement (pathological fractures, scoliosis, and craniosynostosis); and retention of primary teeth. This study aims to characterize intraoral soft tissue findings in HIES patients.


METHODS
Sixty HIES patients (4-54 years, 27 males, 33 females) received intraoral and radiographic evaluations. Chronological dental development was also assessed.


RESULTS
Lesions of the hard palate and dorsal tongue were found in 55% and 60% of patients, respectively. Palatal lesions ranged from a generalized surface keratosis to a midline sagittal fibrotic bridge. Tongue lesions consisted of multiple fissures and a midline cleft. On the lip and buccal mucosa, keratotic plaques and/or surface fissures were found in 8% and 23% of patients, respectively. Manifested in 76.7% of patients, the intraoral lesions were significantly more prevalent than the characteristic facial traits (P=0.0013).


CONCLUSIONS
Alterations in oral mucosa and gingiva were present in the majority of HIES patients. These novel intraoral findings may facilitate the diagnosis of HIES.
