Description

A confined, benign, but occasionally aggressive osteolytic lesion, central giant cell lesions of the jaws. The Central Giant Cell Granuloma (CGCG) is an unencapsulated proliferation of mononuclear spindle-shaped and polygonal cells with multinucleated giant cells of the osteoclast type in a vascular backdrop, with haemorrhage and hemosiderin colouring. A lobular architecture with osteoid and woven bone may be seen in the lesion, separated by fibrous septa. The mandible experiences CGCG development twice as frequently as the maxilla. For the various jaw areas, there was, however, no obvious preponderance. CGCGs can present clinically in a variety of ways, ranging from asymptomatic, slowly expanding lesions without recurrence to painful, aggressive lesions that develop quickly and cause discomfort as well as soft tissue mass and mucosal ulceration. Multifocal CGCG occurs simultaneously in synchronous lesions, but insufficient surgical excision causes recurrences in metachronous lesions. Synchronous involvement is typically linked to syndromes or systemic diseases such as Paget's disease, ossifying fibroma, Brown tumour in hyperparathyroidism, Noonan syndrome, cherubism, fibrous dysplasia, or fibroosseous lesions. Several CGCGs occurring simultaneously without a systemic illness or family history is quite unusual. Brown tumour of hyperparathyroidism may be connected to multifocal CGCGs. Brown tumours and CGCG may have similar microscopic characteristics. Thus, serological analyses are essential for making the correct diagnosis. Hyperparathyroidism is characterised by elevated calcium, alkaline phosphatase, and Parathyroid Hormone (PTH) levels as well as reduced phosphorous levels. Calcium, alkaline phosphatase, and phosphorus levels in the patient were all within acceptable ranges. A modest rise in PTH is explained by a lack of vitamin D, which eliminates the brown tumour from the differential diagnosis. A polyostotic skeletal ailment in people over 40 is called Paget disease. Paget disease may be linked to benign tumours like CGCG as well as malignant cancers like osteosarcoma and fibrosarcoma. A cotton wool look on radiographs and higher levels of the enzyme serum alkaline phosphatase and the amino acid hydroxyproline in the urine are seen. So, in this case, Paget illness is also ruled out. In young people, often between the ages of 2 and 7, cherubism is defined by the development of symmetrical, multiquadrant, multilocular, painless, and expansile radiolucent lesions in the posterior portions of both jaws. In the early stages of illness, swelling and face fullness were caused by submandibular lymph node involvement.

Cherubism and CCCG have a similar histological appearance, however cherubism can still be diagnosed even in the absence of eosinophilic perivascular cuffing, which is what distinguishes it from CCCG. Cherubism can be ruled out by the patient's asymmetrical and painful enlargement, the absence of a related illness in his family history according to the autosomal dominant inheritance pattern, the absence of nodular lymph nodes, and other factors. Several therapies, from medicinal to surgical, are taken into consideration depending on the behaviour of the lesion based on histology and radiographic findings. In order to reduce the likelihood of recurrence, several surgical methods including local excision, curettage, resections, and even peripheral ostectomy were used. The presence of pain, a size of more than 5 cm, rapid growth, tooth displacement or root resorption, and cortical plate thinning or perforations, which are reported in this case and are suggestive of thinking of the lesion as an aggressive type, are all factors that have been postulated in prior studies. Research have also revealed that patients with a mean age of 10.7 years are more likely to have the aggressive one. Also, several investigations have discovered that the histopathologic characteristics of aggressive variations exhibit an increased number of giant cells, a larger surface area, and multiple mitotic activities. Others think that invasiveness of lesions is determined by clinical and radiographic criteria, and that the microscopic appearance has no bearing on this. The lesion in this case is classified as an invasive CGCG based on pathologic findings, clinical, and radiographic criteria. Due to the patient's young age, right side lesion, and worsening discomfort and edoema, a partial mandibulectomy was required. Because of the lesion's early development, triamcinolone 45 mg was injected into the lesion on the left side six times at intervals of three weeks. No indication of a recurrence has been identified as of yet.

Conclusion

When it comes to youngsters, CGCG should be seen as a diagnostic of a lesion that is rapidly growing. Its early detection is crucial to its therapy and can aid in overcoming the difficulties. In this situation, the corticosteroid injection reduced the size of the lesion while simultaneously removing the discomfort. The ideal management strategy for both aggressive and nonaggressive lesions is still being researched.
