Purpose: Glomus tumor is a benign neoplasm of the normal glomus body, occurring as painful subcutaneous nodules, frequently located in the subungual area. There are few cases of facial glomus tumor reported and we report a case of glomus tumor developing on the columella of nose. Methods: A 68-year-old female presented with a mass of the columella grown for 2 years. The nodule was 0.6 cm in diameter, red-colored without any symptoms such as pain, tenderness and cold hypersensitivity. The pathologic result after punch biopsy was hemangiopericytoma. Excision with local anesthesia was executed. Results: The postoperative recovery of the patient was uneventful, Histopathological examination indicated a glomus tumor. Immunostaining revealed positivity for vimentin, actin, and negativity for desmin, CD-34. After 8 months follow up, there is neither complication nor evidence of local recurrence on clinical examination. Conclusion: To accomplish an accurate diagnosis of glomus tumor, the histopathological examination is essential together with immunochemical studies. The differential diagnosis include hemangioma, lipoma, epidermal inclusion cyst, dermoid cyst and arteriovenous malformation in this region. We report a case of glomus tumor on the face with uncommon clinical features.

Running title: A plunging ranula extended into parapharyngeal space Ranulas are lesion of sublingual gland origin, which occur in the floor of the mouth. Most ranulas, whether simple or plunging, are pseudocysts without and epithelial lining and ranulas have higher levels of salivary amylase and protein content. They can be classified into two types based on their extent: simple ranulas, confined to the sublingual space and plunging ranula which extend into adjacent spaces. Plunging ranula requires differential diagnosis with other lesions (neuroma, monomorphic adenoma, hemangioma, lipoma, dermoid cyst, lateral cervical cyst). The patient was diagnosed as plunging ranula. We experienced 17 years old male, visited to our department, who complain Rt. cervical swelling and in MRI view, this lesion involved sublingual, submadibular, parapharyngeal, skull base. We experienced a rare case of plunging ranula, extended into parapharyngeal space. We report the case.

Tuberculosis is one of the most common chronic disease. While the disease process may involve anywhere of the body, tuberculosis of anterior mediastinum which forming tumor like mass was not recognized commonly. We experienced a surgical case of tuberculous empyema thoracis at anterior mediastinum in 16 year old boy. Preoperatively, he was diagnosed to anterior mediastinal tumor such as teratoma or dermoid cyst by routine study. Operation was performed by midline sternotomy extending over right 4th intercostal space. The mass was elongated football shaped [20x16x15] and markedly adhered to right side of pericardium, upper 8< lower lobe of the right lung. Opening the mass, enormous pus-like material was evacuated and excised segmentally with decortication. Postoperative pathologic diagnosis was tuberculous empyema thoracis and granuloma.

Mature cystic teratoma, commonly called dermoid cyst, is the most common benign germ cell tumor of the ovary in children. Malignant transformation is rare, approximately 2 %. As laparoscopic procedures are applied widely in pediatric surgery, a female chlid with a mature cystic teratoma may be an ideal candidate for laparoscopic surgery. Two children received laparoscopic operations successfuly for lower abdominal crises, twisted adnexa. There was no operative complication. Laparoscopic approach for ovarian lesions in infancy and childhood appears to be an effective and safe method for diagnosis as well as definitive therapy.

Currarino triad is a hereditary condition diagnosed when three abnormalities are noted: (1) an anorectal malformation; (2) an anterior sacral defect and (3) a presacral mass. We experienced 3 cases of Currarino triad with severe constipation. All cases had presacral mass and sacral bony defect. One case had rectovaginal fistula, other one case had holoprosencephaly. Presacral masses were lipomeningomyelocele and epidermoid or dermoid cyst. We report three cases of Currarino triad with brief review of the related literature.

Purpose: Chondroid syringoma, previously known as 'mixed tumor of the skin', is a rare benign tumor. It usually presents an asymptomatic solitary firm intradermal or subcutaneous slowly growing nodule. It occurs frequently in the head and neck region of middle-aged men. We would like to report an uncommon chondroid syringoma about the clinical and histologic presentation. about the clinical and histologic presentation. Methods: We experienced two cases of chondroid syringoma on the nose and the upper lip, each other. Both masses were totally excised with clear margin. Results: On histologic examination, the masses showed a biphasic pattern-an epithelial component exhibiting apocrine/eccrine differentiation and a stromal component exhibiting myxoid/collagenous change-consistent with the diagnosis of chondroid syringoma. There have been no evidence of recurrence and malignant transformation during postoperative follow-up. Conclusion: There is no one distinctive clinical feature that is specific for chondroid syringoma. However, it should be included in the differential diagnosis of a solid nodule in head and neck region with long standing duration, such as epidermal inclusion cyst, pilomatrixoma, dermoid cyst, sebaceous cyst, neurofibroma, and basal cell carcinoma.

The survey on branchial anomalies was conducted by Korean Association of Pediatric Surgeons. A total of 173 cases were reported, which were managed by 36 members and cooperators during the three years from January 1, 1993 through December 31, 1995. The following results were obtained by retrospective analysis of the 173 cases of branchial anomalies. The presenting symptoms were cervical mass in 101 cases, pit with or without discharge in 71, cervical abscess in 47 and respiratory difficulty in 3. The average age of the patients with cervical abscess was 52 months. Seventy(79%) of 89 patients with branchial anomalies and a cystic mass had their first clinical manifestations by 1 year of age, while 40(51%) of 78 patients with only a branchial cyst had their first clinical manifestation in first year of life. Radiologic studies were carried out in 77 patients (43%). The preferred diagnostic modalities were ultrasonography(47 patients), simple neck radiogram(19) and CT scan(17). Preoperative diagnosis was correctly made in 156(91%) of 173 patients. Seventeen patients were incorrectly diagnosed as thyroglossal duct cyst in 5 patients, cystic hygroma in 4, dermoid cyst in 3, and lymphadenopathy in 3. There were no remarkable difference in sex and laterality of presentation but bilateral lesions were found in 9(5%) patients and unusual locations of the anomalies were the manubrium, left subclavicular area, median cervial area, preauricular and parotid area. There were 78(45%) patients with cyst, 52(30%) patients with sinus, 35(20%) patients with fistula and 8(5%) patient with skin tag. Embryological classification was possible in only 64(37%) patients. The 2nd branchial anomaly was present in 50(78%), the 1st branchial anomaly in 10(18%), and the 3rd or 4th branchial anomaly in 4(6%). Histopathological study of the lining epithelium(N=134) is recorded that 45% were lined with squamous epithelium, 17% with respiratory epithelium, 6% with. squamous and respiratory epithelium, 14% with inflammatory change. Lymphoid tissue was common(62%) in the wall of the lesions. Twelve(7%) of 158 patients had postoperative complications including wound complication, recurrence and facial nerve palsy.

This report is a analysis of 72 cases of mediastinal tumors which are originated in mediastinum or probably metastasized from other organs, and classified on the basis of histopathological types. And all are experienced in the Depart. Thoracic and cardiovascular Surgery, National Medical Center from 1959 to April 1976. Among these cases, 58 cases were confirmed by histopathologically, and remained 14 cases were considered as mediastinal tumor by clinically and roentgenologically. In this series, dermoid cyst and teratoma was most frequent tumor among histopathologically confirmed cases(27.6%), and thymoma 20.7%, neurogenic tumors 17.2%, carcinoma 19%, lymphoid tumor 8.6% and others was 5.9%. The cases of not verified histopathologically were 14 cases. The main clinical symptoms were dyspnea on exertion or orthopnea (62.55%), productive or irritative cough (59.77%), decreased breathing sound (43. 09%). S.V.C syndromes was seen in 25.02%, and there were no definitive symptom in 4.2% of all cases. The main treatment method was surgical removal and irradiation therapy.

An abnormal Korean native cow of six years old with extra legs was observed macroscopically and radiographically. The results were summarized as follows; 1. External features included two normal forelimbs and hindlimbs, and two extra forelimbs which were underdeveloped. The extra forelimbs of different length attached laterally to the cranial regions of neck on right scapula. 2. The large extra forelimb had scapular meromelia. It consisted of underdeveloped humerus, antebrachial skeleton, several carpal bones, metacapal bone(MC3+4) and two digitis with each pairs of hoof and a rudimentary hoof of dewclaw. 3. The small extra forelimb had scapular and antebrachial meromelia. It consisted of underdeveloped metacarpal and carpal bone, severely deformed humerus, fused carpal bones, and two digitis with two hooves, and a rudimentary hoof of dewclaw. 4. The dermoid cyst was observed between the large and small extra forelimbs.

Recently, video-assisted thoracoscopic surgery for mediastinal lesions has been considered a new effective therapeutic method. From March, 1992 to April, 1997, 33 cases of video assisted thoracoscopic surgery for mediastinal lesions were performed. Gender distribution was 16 males and 17 females. Average age was 42 years old(ranged from 14 to 69). The locations of lesions were anterior mediastinum in 14 cases, middle mediastinum in 5 cases, posterior mediastinum in 11 cases, and superior mediastinum in 3 cases. These included 9 neurilemmomas, 5 benign cystic teratoma, 4 pericardial cysts, 2 ganglioneuroma, 2 thymus, 2 thymic cyst, 1 thymoma, 2 esophageal leiomyomas, 1 dermoid cyst, 1 lipoma, 1 malignant lymphoma, 1 bronchogenic cyst, 1 pericardial effusion, and 1 Boerhaave's disease with empyema. Working window was needed in 6 cases. We converted to open thoracotomy in 6 cases. Reasons of convertion to open thoracotomy were large sized mass(1), severe adhesion(3), and difficult location to approach(2). The average operation time was 116min($\pm$56 min). The average chest tube drainage time was 4.7days. The average hospital stay was 8.7 days. Operative complications were atelectasis(2), empyema with mediastinitis(1), recurrent laryngeal nerve palsy(1), and plenic nerve palsy(1). In conclusion, VATS for mediastinal lesions were performed with shorter operation time and hospital stay, and lesser complications and pain than those of conventional thoracotomy.
