Central giant cell granuloma formation in an edentulous area in the posterior portion of mandible: A case report

INTRODUCTION: Central Giant Cell Granuloma (CGCG) is a non-neoplastic benign lesion. It is primarily observed in the maxilla and mandible, with the mandible being the more reported site of the lesion.

Sumario:INTRODUCTION: Central Giant Cell Granuloma (CGCG) is a non-neoplastic benign lesion. It is primarily observed in the maxilla and mandible, with the mandible being the more reported site of the lesion. The lesion often manifests in the anterior regions of the mandible, extending occasionally across the midline. This case reports a rare presentation in the posterior portion of the mandible, in an edentulous area. PRESENTATION OF CASE: A 33-year-old female with a history of extraction of teeth 36 and 37 six months ago presented with a main complaint of a mass in the oral cavity. The oral examination revealed an expansive multilocular mass (4 × 3 cm) located on the alveolar ridge in the left posterior portion of the mandible, extending around tooth 33 with an intact masseter muscle. The histopathological findings were consistent with CGCG. Consequently, the lesion was surgically removed with no clinical or radiological recurrence observed during the 4-month post-operative follow-up. DISCUSSION: While previous reports of CGCG in the posterior portion of the jaw showed destructive lesions that caused mandibular ramus destruction along with swollen masseter muscle, this case reports no involvement of the masseter muscle. Also, while some studies linked CGCG to tooth-bearing regions, our case suggests a possible traumatic link even after extraction. CONCLUSIONS: This case presents a rare CGCG occurrence in the posterior jaw, notably without masseter muscle involvement. It also indicates that CGCG can manifest in edentulous regions.
