It has been widely accepted that distant metastasis of the hepatoma to the other organs so readily occurs that about 50% of cases are discovered to have already been metastatic at an appointement of diagnosis. The prognosis of hepatoma mainly depends on the size, shape and residual function of the liver, and not so much concern was given to the distant metastasis. But recently, by the means of early detection, embolization of hepatic artery and radiotherapy, survival period of the patients is getting longer. And as a result the distant metastasis is more emphasized. Hepatoma metastasizes primarily to lung, and in the order of lymph node in the abdominal cavity, parathyroid gland, and bone. In a few cases, the biopsy of the metastatic area reveals that the primary site is the liver. Primary hepatoma, metastatic to the mouth are and most cases are diagnosed that primary site of occurrence is liver, through the biopsy at the time of visit due to the mass in the oral cavity. In this context, the authors report 2 cases of primary hepatoma which metastasized to the mandible and gingiva. One case, a 60 year old man in 1988, was diagnosed by the biopsy because of the mass in the left mandibular body and the ramus, after that the abdominal ultrasonography and abdominal computerized tomography were done to identify the metastasis of the hepatoma. Resultantly the final diagnosis was primary hepatoma that metastasized to the mandible. And the other case, 61 year old man in 1992, was diagnosed through the intraoral biopsy and hepatocellular aspiration because of the rapidly growing mass on the gingiva. This case was also diagnosed to be a primary hepatoma.

Chondrosarcoma is a rare malignant neoplasm which constitutes approximately 10% of all primary malignant bone tumors. It occurs most often in the pelvis, femur, rib and humerus and the involvement of the jaw is rare, and what is more, chondrosarcoma arising in the condyle is extremely rare and only a few cases were previously reported and there is no domestic report. We report a chondrosarcoma of a condyle presenting as a painful swelling on the left preauricular area.

Plasmacytoma is one of the malignant neoplasm that originate in immunoglobulin-producing plasma cell, and occurrence in gingiva is known to be rare. About 7% of all patients with plasma cell malignancies present with solitary lesions in bone or soft tissues. In 30% to 40% of patients, the disease progresses to mulitiple myeloma on long-term follow-up. the incidence of progression to multiple myeloma is higher in patients with a bone lesion as compared with an extramedullary lesion. Several studies have shown a relatively favorable course for both these groups of patients, but many long-term studies have demonstrated the distinct difference in ultimate prognosis between patients with solitary lesions in bone and those with extramedullay lesions. The primary objective in the past has been to suppress the immune system to permit allotransplantation. But immunosuppressant also increases the incidence of malignant neoplasms in patients after allograft transplantation. We treated a 15-year patient with plasmacytoma on gingiva who had received kindny transplantation & immunosuppressant therapy. We excised this lesion & performed radiotherapy and had a favorable result.

For the complete cure of oral cancer suspected to have invaded the mandible in clinical & radiological evaluation, the mandible resection in planned. The aim of this clinical study was to help in decision making in the method & the extent of the mandibular resection surgery. This study was conducted on 46 oral cancer patients, who received cancer surgery including mandibulectomy. And we evaluated the relationship between the pathologic results of resected mandible and the location, size and clinical newk node involvement, tumor cell differentiation. The results are that ; (1) Hiher incidence of bone invasion patterns were observed in tumor of mouth floor & gingiva compared to those of tongue & tonsil, and (2) No significant relationship was found between bone invasion of tumor and tumor size, neck node involvement tumor cell differentiation. The approximation between tumor and bone seems to be the most reliable factor among the other factors in decision making of mandibular resection.

Thyroid carcinomas are usually classified as papillary thyroid carcinoma, follicular thyroid carcinoma, medullary thyroid carcinoma and anaplastic thyroid carcinoma. Among the thyroid carcinomas, the incidence of medullary and anaplastic thyroid carcinoma is low, but the rate of lymph node & distant metastasis from them are more common compared to other types. Follicular thyroid carcinoma has a low rate of lymph node metastasis as 10% and has a high occurrence of hematogenous metastasis to lung, bone, brain and liver. Papillary thyroid carcinoma accounts for 60∼70% of whole thyroid carcinomas and the cervical lymph node metastasis is 21∼81% including micrometastasis, but the distant metastasis is rare. In the case of bone metastasis, follicular type reveals most frequent, and the rate is about 5%, and more likely to be found on vertebra, pelvis, ribs, femur, and skull. The clinical symptoms of bone metastasis are pain, swelling, pathological fracture and radiologically osteolytic lesions can be observed. But distant metastasis of papillary thyroid carcinoma is very rare and especially, bone metastasis has hardly been reported. The treatment modalities of metastatic thyroid carcinoma to mandible are known as follows : thyroidectomy to treat primary site, resection of the affected site of mandible, external beam radiotherapy and radioiodine therapy etc.
대상포진 환자에서 발생된 상악골 골괴사 : RARE COMPLICATION IN PATIENTS WITH HERPES ZOSTER

Herpes Zoster is an acute viral infection characterized by the appearance of vesicles that occur on the skin and mucous membrane along the pathway of an involved sensory nerve. Although Herpes zoster is usually as benign viral infection, complications may occur especially when cranial nerves are involved. There are few reports of bony and dental complications by Herpes Zoster infection, all of which were isolated in a single quadrant. These include devitalized teeth, abnormal development of permanent teeth, internal resoption and spontaneous exfoliation of teeth with osteonecrosis of the alveolar bone. No agreement has been reached concerning the pathogenesis of osteonecrosis and tooth exfoliation associated with herpes zoster infection. We recently experienced series of maxillay osteonecrosis and spontaneous teeth exfoliation in patients with Herpes Zoster infection and present two cases with review of literature.
