Renal cell carcinoma (RCC) is the most frequent urological malignant tumor in adults and it occurs mostly between the fifth and the sixth decades of life. The male-female ratio is 3:1 and it is more common in smokers. It accounts for approximately 3% of adult malignancies; 90~95% of neoplasms of the kidney. The classic triad of presenting symptoms of RCC is hematuria, back pain and a mass in the flank. More than 50% of RCCs show metastasis to breast, lung and regional lymph nodes, and 15% present in the orofacialmaxillary region. This case is about a 66 year-old man who was treated for painless swelling in the left masseteric area. The mass was surgically excised and sent for biopsy. It was diagnosed as RCC and two weeks later nephronectomy of the left kidney was performed. Metastasis to other organs was detected and the patient received radiation therapy. In this case we were able to find the primary lesion by the metastatic lesion.

Radiation therapy for malignancy of head and neck leads to secondary effects, such as mucositis, xerostomia, dental caries and osteoradionecrosis. Osteoradionecrosis is a delayed complication which causes chronic pain, infection and constant deformity after necrosis. It occurs spontaneously or after primary oncologic surgery, dental extraction or by trauma of prosthesis. To reduce the incidence of osteoradionecrosis, appropriate antibiotic usage, atraumic procedure, tension-free primary suture and hyperbaric oxygen therapy are essential. This case is about a 74 years old woman who was treated for osteoradionecrosis after extraction of right lower molar at year 2006. She had received radiation therapy for angiosarcoma on tongue at year 2004. At year 2008 the patient came to our hospital for extraction of the opposite premolar but despite careful treatment, osteoradionecrosis occurred again. She was successfully treated by surgical procedure so we report this case.

Bisphosphonates are widely used to treat osteoporosis, hypercalcemia of malignant tumor. Despite their clinical benefit, bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a newly documented complication to patients receiving these drugs and first recognized by Marx in 2003. Thus, consideration of prevention and needs regarding unequivocal treatment regimen have emerged. Recently, several authors emphasized reports on appropriate clinical availability of surgical approach. It serves to concern about guideline for surgical and conservative treatment modalities. So, it is the purpose of this paper to review the current literatures about treatment regimens of BRONJ.
