Focal epithelial hyperplasia in infants
Keywords:
Mouth mucosa, Pediatric dentistry, papillomaAbstract
The human papillomavirus is a group of double-stranded DNA viruses that may
be present in the host cell. Human papillomavirus-infected epithelial cells
undergo transformation and proliferation, evolving into verrucous lesions. The
usual incubation period is between 1 and 3 months. The objective of the
present study is to report the clinical case of an infant presenting with a
hyperplastic, papillomatous lesion of the palate a few days after birth. Patient
E.B., male, 3 years old, arrived at the Pediatric Dentistry Clinic of the School of
Dentistry of the Pontifical Catholic University of Campinas with pedunculated
hyperplastic incisive papilla in the hard palate region. A biopsy was performed
and the material was fixed in 10% formalin for anatomic and pathological
analysis. Microscopic examination of the specimen showed a hyperplastic,
papillomatous epithelial lesion due to a mildly active chronic inflammatory
process and absence of malignancy. Anamnesis and clinical examination in
pediatric dentistry should include a detailed examination of the patient for an
accurate diagnosis and appropriate therapy for hyperplastic lesions.
