The present case illustrates an arteriovenous malformation of the cheek in a 25-year-old male. The clinical presentation. radiographic findings, differential diagnosis, treatment and histopathologic description are presented. Diagnosis of the lesion was confirmed by angiography, and the lesion was treated by angiographically controlled vascular embolization followed by complete surgical excision.

Angiofollicular lymph node hyperplasia is a relatively rare benign lesion. It develops most often in the mediastinum, but also it found in other area of the body, usually where lymph nodes are normally found. There are histologically divided hyaline vascular type, plasma cell type and transitional type. The lesions were discovered most often on routine roentgenograms, and complete surgical excision is the treatment of choice. Recently, the authors experienced a case of angiofollicular lymph node hyperplasia, transitional type, located in the right hilar area. The lesion was removed and the patient is in good condition postoperatively. Now we report this case with review of previously reported literatures.

mediastinal teratomas are encountered commonly in adult life, and rarely in childhood. Characteristically, these mediastinal teratomas are located anteriorly with only rare examples in the posterior mediastinum. The cystic teratoma usually behaves as a benign neoplasm, but the solid [non-cystic] teratoma is frequently malignant. We experienced a case of large anterior mediastinal cystic teratoma in a two-years old boy, which was treated by complete surgical excision with good result.

Primary malignant fibrous histocytoma(MFH) of pleura is very rare. Upon microscopic examination, the tumor was characterized by storiform pattern of growth and intense, diffuse immunostaining for $\alpha$ l-antichymotripsin. We report a case of primary malignant pleural fibers histiocytoma with extension to lung, which was managed by complete excision of pleural mass and lobectomy with thoracoplasty.

Cystic lesion which is located in vallecular area is sometimes symptomatic and need surgey. But surgical route to this area is divided external approach into internal one. Internal approach via transoral route with suspension laryngoscope can avoid disadvantages of external approach but conventional laryngoscope is not suitable for this type of procedure. We used Steiner laryngopha-ryngoscope in surgery for vallecular cyst and we could excise cyst easily. Of 20 cases, complete excision was tried in 18 cases and marsupialization in 2 cases. Recurrence was 1 case. We suggest that surgery using laryngopharyngoscope is effective in treating cyst which is located in vallecular area.

From Aug. 1975 to Aug. 1981,3 patients with primary benign rib tumors have been treated at the department of thoracic surgery, Paik Hospital, Seoul, Korea. Of these, one was aneurysmal bone cyst and two were fibrous dysplasia. Complete excision of the benign tumor including rib resection was performed in all patients and resulted in long term cure.

The 5-aminolevulinic acid (5-ALA)-induced tumor fluorescence is a useful intraoperative marker for the diagnosis and the detection of various malignancies, but its use in meningioma is only reported infrequently. In meningioma, a complete resection of the tumor mass is crucial for the prevention of recurrence and postoperative morbidities. Deep sylvian meningioma is a rare type of meningioma where complete tumor removal is complicated by its deep anatomical location and close involvement with the middle cerebral artery. From our experience, 5-ALA-mediated fluorescence facilitated a safe excision whilst preserving critical neurovascular structures. To our best knowledge, this is first report from use of 5-ALA in a deep sylvian meningioma.

Objectives: Tuberculous cervical lymphadenitis is a frequently recurring disease when treated with chemotherapy alone without enough surgical removal of the tuberculous lesions. Authors reviewed retrospectively the treatment result of antituberculous chemotherapy following almost complete surgical removal of tuberculous foci in the neck. Materials and Methods: A retrospective clinical review and analysis was made in 127 cases of tuberculous cervical lymphadenitis patients treated during the past 10 years from 1989 to 1998 at the Department of General Surgery, Inje University Paik Hospital, Pusan. Results: 1) The peak age incidence was the 2nd decade(37.8%), and female was predominated over male by 2.3:1. 2) The time interval from the onset of symptoms to the first visit was less than 3 months in 60.6% of the patient. 3) The location of lymphadenitis was the right neck in 60%, the left neck 34%, and bilateral in 6% of the patient. 4) Signs on the first visit showed solitary masses(60%), abscess(25%) and both mixed(15%). 5) 25 patients(19%) had present or past history of tuberculosis; pulmonary tuberculosis 12 patients, tuberculous lymphadenitis 10 patients, and others 3 patients. 6) Locations of tuberculous lymphadenitis were posterior cervical triangle 70, supraclavicular 51, submandibular 19, anterior triangle 16 and others 4 cases. 7) The principle of treatment of cervical lymphadenitis was surgical management followed by chemotherapy. Surgical procedures were excision(s), curettage and drainage of abscess, combination of both, and biopsy in 60%, 22%, 12% and 6% respectively. Mean duration of antituberculous medication was 9 months after surgery. 8) The rate of recurrent and persistent tuberculous lymphadenitis was 9% in 4 years follow up. Conclusion: Tuberculous cervical lymphadenitis is a frequently recurring disease in young adult when only antituberculous chemotherapy was employed without almost complete removal of the lesions. It is considered that antituberculous medications for 6-9 months after removing the foci at a maximal extent by surgical excision and curettage will reduce the recurrence rate or persistence of tuberculous lymphadenitis.

혈관외피세포종은 구강 내에서 매우 드물게 발생되는 종양으로 양성과 악성의 구분이 매우 어려운 종양이다. 이의 치료는 외과적인 완전 절제이나 오랜 시간이 지난 후에도 재발과 전이가 발생될 수 있으므로 술후 장기간의 주기적인 관찰을 요한다. 이에 저자 등은 30대 여자 환자의 협점막에 발생한 혈관외피세포종을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Mesenchymal hamartoma of the liver is a rare benign tumor, usually presenting in early childhood, Five children with mesenchymal hamartoma of the liver pathologically verified at Seoul National University Children's Hospital between 1978 and 2000 were analyzed retrospectively. There were two girls and three boys, and their mean age at the operation was 16.0months (range, 4-32 months). Three patients presented with abdominal distension. A patient was detected incidentally, and another was detected by prenatal ultrasongraphic examination. Tumor size ranged from $10{\times}8.5cm$ to $34{\times}29cm$. Three tumors were located in the right lobe and two in the left lobe. Four cases underwent complete surgical resection, and the other one underwent incomplete surgical resection and marsupialization. Recurrence or malignant transformation was not noted. Five patients survived without evidence of disease for 35, 36, 38, 142 and 228 months. In conclusion, although mesenchymal hamartoma of the liver is benign lesion. it may be confused. and mixed with embryonal sarcoma. A recent report showed recurrence or malignant transformation after partial excision of the tumor. Therefore. complete excision of the tumor with surrounding normal liver tissue is recommended.
