Giant cell tumor of maxillofacial bone

Introduction to giant cell tumor of maxillofacial bone Giant cell tumor of bone is mainly composed of multinucleated giant cells and small fusiform or round interstitial cells. The giant cells are large and contain many nuclei, sometimes ranging from tens to hundreds, fusiform or circular. The morphology of the cytoplasm. Distribution and arrangement are the main basis for determining the nature of giant cells. Generally, the tumor is divided into three grades, the first grade is benign, the second grade is latent malignant, the third grade is malignant, and the macroscopic tumor of the naked eye is a granulation tissue that is easy to hemorrhage. The capsule is easy to hemorrhage and necrosis. The hemoglobin changes the tumor to reddish brown or green. The hematoma fibrosis makes the tumor appear grayish white, the tumor tissue is necrotic, and the tumor may be yellow or form a pseudocyst. The capsule may contain glue. The shape or brown liquid, during the process of tumor progression, bone destruction and regeneration alternately and repeatedly, so the cortical bone expands outward and thins, and finally the tumor is worn. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: jaw cancer, maxillofacial lymphangioma

The cause of giant cell tumor of the maxillofacial region

The etiology and pathogenesis are still unclear. It has been suggested that the incidence is related to trauma.

Prevention of giant cell tumor of maxillofacial bone

Bone giant cell tumor can be a benign tumor or a malignant tumor according to its pathological and structural features, but it is the first choice for benign or malignant surgery. On the one hand, the lesion is removed, and the surgically removed lesion can be used as a pathological examination to determine the tumor. The nature, in order to facilitate further treatment, should not be expected to be applied to the external use of drugs to eliminate the disease, clinically, there are many cases of loss of treatment opportunities due to untimely surgery, should be given attention.

Maxillofacial giant cell tumor complications Complications Jaw cancer and maxillofacial lymphangioma

Common cervical lymph node metastasis.

Symptoms of giant cell tumor of maxillofacial bone Common symptoms Occlusal relationship is ambiguous, emotional facial pain, facial deformity, tooth loosening and detachment of jaw sulcus

1. Jaw bulging and facial deformity, early no symptoms, slow growth.

2. There are loose teeth and occlusions when the alveolar bone is affected.

3. X-ray film shows soapy foam or peak-shaped cystic shadow with bone swelling.

Examination of giant cell tumor of maxillofacial bone

1. For clinical manifestations, the preoperative diagnosis has confirmed the case to check the frame limit "A".

2. For the atypical clinical manifestations, the differential diagnosis is more difficult, the larger the tumor is closely related to the surrounding important structure or suspected to be malignant. The examination plan may include the examination box "B" and "A", for malignant giant cell tumor of the bone. MRI was used to detect cervical lymph node metastasis.

Diagnosis and diagnosis of giant cell tumor of maxillofacial region

diagnosis

1. Jaw bulging and facial deformity, slow growth.

2. The teeth are loose and the bite is disordered.

3. X-ray film shows soapy foam or honeycomb-like cystic shadow with bone swelling.

4. Pathological examination confirmed.

Differential diagnosis

The diagnosis of this disease must be differentiated from mandibular osteoblastoma and giant cell repair granuloma.
