Recurrent benign cementoblastoma: A case report and literature review

Abstract

A 16-year-old male presented with pain in the right posterior mandible on chewing that had lasted for several months. The radiographic features of the lesion included a radiolucent-radiopaque mixed-density mass with a radiolucent rim attached to the root of the mandibular right first molar. The preliminary radiographic diagnosis was benign cementoblastoma, which was confirmed by histopathological examination following surgical excision. The lesion recurred 3 years after treatment; radiographically, it consisted of 3 round foci with mixed radiopacity, each with a radiolucent rim near the root of the mandibular right second premolar and the edentulous postoperative region. The lesion was diagnosed as recurrent benign cementoblastoma and a second surgery was scheduled. This report presented an unusual case of recurrent benign cementoblastoma following surgical excision and extraction of the involved tooth, along with a literature review on reported cases of recurrent benign cementoblastoma with a focus on its clinical features and the best treatment options.

Recurrent cementoblastoma in mandibular first molar region: A case report

Uma Revisão Atualizada do Cementoblastoma Mandibular e Relato de Caso

“…O cementoblastoma é classificado como uma neoplasia benigna, embora sua etiologia não seja totalmente compreendida. É um consenso que possui uma origem do tecido mesenquimal e que é uma lesão relativamente rara, correspondendo a menos de 1% de todos os tumores odontogênicos 1,2 .…”

“…75% dessas lesões encontram-se na mandíbula, principalmente associadas aos molares e pré-molares inferiores. Não há predileção por sexo, afetando igualmente homens e mulheres 2 .…”

“…Os jovens adultos e adolescentes são os mais afetados pelo cementoblastoma, com a maioria sendo diagnosticada em pacientes com menos de vinte anos de idade 2,3 .…”
