Maxillofacial challenge: Rare presentation of central giant cell tumor involving both maxilla and mandible.

introduction and importanceCentral giant cell tumor (CGCT) of bone is an uncommon yet locally aggressive neoplasm originating from undifferentiated mesenchymal cells in bone marrow. This case report explores a rare presentation in the maxilla extending to the mandible, emphasizing the complexity of CGCT management and the need for a multidisciplinary approach. CASE PRESENTATION: A 35-year-old female presented with a progressively enlarging non-tender, firm swelling on the left maxilla and a similar mandibular swelling. Paraesthesia of the left lower lip and chin accompanied the mandibular swelling. CT scans and 3D reconstructions revealed expansive osteolytic defects affecting the maxilla and mandible. Biochemical tests supported a central giant cell tumor diagnosis. Histopathology confirmed spindle cell proliferation and multinucleated giant cells in both lesions. Surgical intervention involved excision and reconstruction. A five-month follow-up showed no recurrence, affirming the treatment's success. CLINICAL DISCUSSION: Central giant cell tumors (CGCTs) of bone are primarily benign, arising from undifferentiated mesenchymal cells. While mostly benign, they carry a rare potential for malignancy. Diagnosis involves imaging (CT, MRI, bone scintigraphy) and confirmation through biopsy. Surgical resection is the standard treatment, with radiotherapy considered in challenging cases. Recurrence rates vary with the extent of surgical intervention. Alternative treatments like cryotherapy and chemotherapy show varying success.

conclusionThis case emphasizes the necessity of precise histopathological diagnosis for CGCT management. The intricate nature of maxillary involvement, coupled with mandibular association, mandates a multidisciplinary approach. Surgery, while the primary treatment, should be judiciously determined based on tumor characteristics and recurrence.
