Abstract

Introduction: pediatric gnathic lesions are commonly asymptomatic and diagnosed in routine imaging exams. However, some of them may cause pain, facial asymmetry, bone destruction and rapid evolution, requiring accurate and early diagnosis. Objective: the aim of this study is to report the diagnosis and treatment of an extensive dentigerous cyst (DC) in a pediatric patient. Case report: a 5-year-old boy complained of painful swelling in the posterior region of the mandible with an evolution time of 4 months. Computed tomography showed a hypodense, well-delimited image involving the crown of tooth 37, causing buccal cortical expansion and lingual cortical erosion, measuring approximately 3cm. With the diagnostic hypotheses of ameloblastic fibroma or DC, the lesion was completely enucleated. Microscopically, a cystic lesion with an odontogenic epithelial lining with areas of hyperplasia and exocytosis was observed, in addition to a densely collagenous connective tissue capsule, with areas of hemorrhage and lymphoplasmacytic inflammatory infiltrate. Results: based on clinical, imaging and histopathological characteristics, the final diagnosis was inflamed DC. The patient remains under clinical and radiographic follow-up, with no recurrence. Conclusion: inflamed DC in pediatric patients may show a peculiar behavior and mimic other odontogenic lesions. Early diagnosis allows for lower morbidity associated with surgical treatments.
