Central giant cells lesion: Report of a conservative management

Pharmacological therapy for central giant cell granuloma of the jaws: A systematic review

Background

Pharmacological therapy has been used as an alternative or complementary approach to surgery in central giant cell granuloma (CGCG) of the jaws. This systematic review examined the effectiveness of pharmacological therapy for CGCG of the jaws, focusing on clinical outcomes.

Material and Methods

Electronic searches were performed in six databases. Case reports and/or cases series were included. The Kaplan-Meier survival analysis method was used to evaluate outcomes related to clinical resolution and recurrence. The risk of bias was assessed using the Joanna Briggs Institute tool.

Results

A total of 74 studies comprising 205 cases of CGCG were included. About 65.4% of cases occurred in individuals under 20 years of age. Most of the treated patients were women (61%) and the mandible (72.2%) was the most reported site. Curettage and enucleation before or after pharmacological therapy were reported in 28.3% and 19% of cases, respectively. The main pharmacological agent used was triamcinolone (37.5%). Complete resolution of CGCG was reported at a rate of 77.1%, while side effects were experienced by 9.8% of individuals. The recurrence rate was 6.8%.

Conclusions

Pharmacological therapy may be an effective and safe option for managing CGCG, especially in the young population. Although the overall success rate in achieving complete resolution is encouraging, further controlled studies are needed to refine drug selection and protocols.

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. 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.

Unravelling the role of immunohistochemistry in giant cell lesions of jaws: A systematic review

Controversies exist in literature regarding nature, pathogenesis, and behaviour of giant cell lesions (GCLs) of jaws. Studies were attempted to solve these mysteries with immunohistochemical analysis, using various biological markers. Thus, the aim of this review is to appraise the role of immunohistochemistry (IHC) in evaluating the pathogenesis, cellular phenotype, nature, and behaviour of GCLs of jaws. PubMed, PubMed Central, and Clinical Key (Medline) databases were searched electronically irrespective of date of publication with assortment of several independent terms. Fifty-five articles that fulfilled the eligibility criteria were included in the review. Out of 55 included articles, 49 were associated with nature, pathogenesis, and behaviour and six articles were associated with treatment and outcome prediction. Although IHC solved some of the controversies associated with GCLs of jaws such as the osteoclastic phenotype of multinucleated giant cells, immunoexpression of proliferative markers does not distinct non-aggressive from aggressive central GCL but the nature, histogenesis, pathogenesis, and exact behaviour still remain debatable. With regard to formulation of treatment plan, immunohistochemical analysis revealed that expression of glucocorticoid and calcitonin receptors could act as a tool to decide the therapeutic strategy and aid in therapeutic adjustments according to evolution of the lesion.

Intra-Lesional Medicaments for the Management of Intra-Osseous Lesions of Maxilla and Mandible - Systematic Review

Aims and Objectives:

This study aimed to review the success or remission of intralesional medicaments in the management of intraosseous lesions in the oral cavity.

Materials and Methods:

A comprehensive search was performed in two databases (PubMed and Scopus). Research articles, case reports, case series, and clinical trials were included. Review articles, lesions not involving the bone, incomplete reporting, any other treatment other than intralesional medicaments to treat intraosseous bone lesions, publications without any treatment, and letter to editor were excluded. Data on remission (complete, partial, or no remission), details and regimen of the intervention, number of participants, and follow-up in months were recorded.

Results:

A total of 653 publications were available for title and abstract screening after the removal of duplicates. Seven articles were excluded, which were not in English. After title and abstract screening, a total of 88 publications were available for full-text screening. Fifty-five articles were included in qualitative synthesis. A total of 168 patients from 55 publications were evaluated. Minimum follow-up was 1 month and maximum was 264 months. More than two-third (n = 38) of the publications were case reports on single patient. More than two-third (n = 38) of the publications had complete remission.

Conclusion:

Intralesional medications have shown variable success rates. Extensive lesions may undergo intralesional medications followed by surgical management.

Central Giant Cell Granuloma Treated with Intralesional Corticosteroid Injections and Bisphosphonates: A Long-Term Follow-Up Case Study

Central giant cell granuloma (CGCG) is a benign intraosseous lesion of the head and neck with potential for aggressive and locally destructive behaviour. Lesions of the maxilla tend to expand more than those of the mandible due to the thinner cortices and spongy tissue of this location. Surgical removal is the most common treatment; however, it may be disfiguring in aggressive cases, especially for lesions located in the maxilla. Alternative treatments, such as intralesional corticosteroid injections, have been performed with satisfactory results. We report a case of a 12-year-old female patient with a CGCG of the left maxilla that was treated with 40 doses of intralesional triamcinolone acetonide infiltrations combined with alendronate sodium and calcium carbonate. Clinical and imaging follow-up over 12 years demonstrates improvement in the patient's condition.
