비인강암의 강내조사법은 외부조사후 추가조사법으로서, 또한 재발병소에 비교적 용이하게 재조사할 수 있는 장점이 있으며 비인강암의 국소치유율을 상승시킬 수 있다. 저자는 비인강암 환자에게 추가조사법으로서 또한 재발된 예에서 비인강암의 강내조사를 시행하여 보고하는 바이다.

Surgery has been known to be traditional treatment modality for the malignant salivary gland tumor, the tumors being considered as radioresistant. However, reviews of the literature have shown a high recurrence rate, especially in advanced and/or high grade tumors. The retrospective data suggests that conservative surgery with adjunctive radiation therapy is justified in view of the enhanced locoregional control. In inoperable and recurrent tumor, definitive radiotherapy can achieve $30{\sim}40%$ of average 5 year survival rate, but in early stage, local control and survival rate could be raised more than 80%. This results shown to be aggressive radiotherapy can replace surgical management for the selected cases of small sized tumor. Neutron therapy is another option for curative treatment of malignant salivary gland tumors.

A 25 years old male patient with Hodgkin's disease, considered as complete remission, underwent $^{18}F$-FDG whole body PET/CT. $^{18}F$-FDG whule body PET/CT showed unexpected hypermetabolic nodule in left quadratus femoris muscle suggesting local recurrence. Subsequent MRI also revealed well-enhancing nodular lesion with intermediate and high signal intensity on T1WI and T2WI, respectively. The lesion was confirmed as nodular fasciitis by pathologic examination of the excited specimen.

The incidence of plunging ranula has been reported as about 10% of all ranula cases. Treatment consists of wide surgical excision or marsupialization. However, it seldom provides a satisfactory result and various modalities of treatment have been proposed in addition to surgical extirpation. We reported our experience using intralesional OK-432 sclerotherapy for a case of plunging ranula in 20 year-old male patient. The OK-432 solution was prepared by dissolving 0.1 KE in 2ml of physiologic saline and was instilled in the same amount of the aspirated cystic fluid. Following two instillations, the lesion completely disappeared. The side effects were mild fever for 3 days and a mild local induration for several days. At present, 9 months after instillation, no recurrence was observed. OK-432 sclerotherapy appears to be simple, safe and effective method for the treatment of plunging ranula.

Adenoid cystic carcinoma is a rare primary tracheal tumor, and this tumor behave slow growth, low grade malignancy with local invasion. Although many patient die within 2 to 3 years of the onset of symptoms without appropriate treatment, adequate therapy should lead to survival of 10 years or more. We had a case of adenoid cystic carcinoma in 47 year old female patient who was treated with resection and end-to-end anastomosis of the invaded trachea. Postoperative course was uneventful and discharged without any complications. Radiotherapy of total 6,600 cGy is scheduled 4 weeks after the resective surgery to prevent recurrence.

We experienced a rare case of parosteal lipoma, which located on the periosteum of the foot 4th metatarsus. A 22-year-old woman visited the hospital with painful mass in her foot. Based on the assessment of plain radiographs, computed tomography scan, and magnetic resonance image, it was suspected as lipoma. Marginal excision was performed and parosteal lipoma was confirmed histologically. Any local recurrence and complications were not observed in 2 years after surgery.

Complete vertebral tumor resection is important in order to prevent local recurrence. Among the available techniques for total spondylectomy, the total en bloc spondylectomy has been accepted as the most sophisticated one. After a total en bloc spondylectomy, anterior and posterior column reconstruction is mandatory in order to achieve stability. We experienced the usefulness of an expandable cage for anterior column reconstruction especially in this surgery. The chance of cutting the nerve root and damaging the spinal cord is minimized because the size of the expandable cage is initially small enough to be inserted into the anterior column. The technical details of total vertebral body replacement with an expandable cage after an en bloc lumbar spondylectomy are described herein.

Objective : Hemangiopericytoma is known as a malignant tumor originating from pericytes and rarely occurs in the central nervous system. We present 6 cases of pathologically confirmed meningeal hemangiopericytoma. Methods : Retrospective study was done based on patient's recordings including radiological studies. Each case of tumors was treated surgically and postoperative radiotherapy was done. Results : There were 5 cases of intracranial and 1 case of spinal hemangiopericytomas. Three of 5 intracranial hemangiopericytomas were located at tentorial region. Total tumor removal was done in 4 cases and postoperative local recurrence (or regrowth) was noted in 3 cases despite of postoperative external radiation therapy, 2 of which had died. Conclusion : Our cases show more frequent tentorial locations and poor clinical outcomes of hemangiopericytomas compared with meningiomas.

Hemangiopericytomas, which used to be classified as the subtype of the meningiomas, like the angioblastic meningiomas or hemangiopericytic meningiomas, are rare in the central nervous system with an incidence of <1% of all central nervous system(CNS) tumors. In spite of a total surgical removal, hemangiopericytomas have a tendency of high local recurrence and distant metastasis. The authors report a case of hemaniogipericytoma recurred at the remote area from the primary site. The tumor recurred in the meninges of right temporal area after total removal of the tumor in the right parasaggital region including the falx.

Although brain metastasis of renal cell carcinoma is a major cause of death in Von Hippel-Lindau disease(VHL), it is not easy to distinguish local recurrence of hemangioblastoma from distant metastasis. In addition, hemangioblastoma has several characteristics suitable for recipient of "tumor-to-tumor metastasis". Authors report a case of Von Hippel-Lindau disease that had metastases of renal cell carcinomas.
