Two cases of benign mediastinal tumor were treated by complete resection under the video-thoracoscopic guidance. The procedure has been performed on the 2 patients, allowing definite treatment and was less invasive than standard surgical treatment. The 2 patients have been benefited by decreased postoperative pain, reduced scarring of the skin and rapid recovery. Two patients had benign mediastinal tumors; teratodermoid on anterior mediastinum and neurilemmoma on posterior mediastinum. There were no operative death and complication, median hospital stay was four days.

This report is an review of 40 cases of mediastinal tumors which were treated surgically in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital from January, 1985 to September, 1989. In this series, male to female sex distribution was 1.35:1 with the male predominant. The main clinical manifestations were chest pain and dyspnea, and there was no definitive symptom in 5 cases [12.5 %]. The most common mediastinal tumor was thymoma, 11 cases [27.5 %], and next common mass was germ cell tumor, 9 cases [22.5 %]. The half of these were malignant. In operating, all of the benign masses were removed.

Thymolipoma is a rare benign mediastinal tumor, composed of mature fatty and thymic tissues. A 9-year-old boy was referred with a one-month history of neck swelling. Preoperative computed tomography scan and fine needle aspiration biopsy suggested thymolipoma. Despite it being rare, thymolipoma should be considered in the differential diagnosis of mediastinal tumors. Characteristics of its clinical feature and radiological findings that can differentiated it from other mediastinal tumors are discussed with a review of the literatures.

Angioleiomyomas are a vascular subtype of leiomyomas or benign smooth muscle tumors. The majority of these tumors occur in the extremities. Angioleiomyoma of the larynx has been reported but is exceedingly rare. Laryngeal angiomyomas can present with hoarseness, dyspnea, or globus sensation, and often misdiagnosed as asthma. We report a case of a 74-year old man with laryngeal angioleiomyoma misdiagnosed as asthma.

Although hemangiomas are common vascular tumors that can occur anywhere in the body, they seldom involve the gastrointestinal tract. Hemangiomas of the gastrointestinal tract in infants and children are rare benign vascular tumors that most commonly present with gastrointestinal bleeding. We describe here the case of 2-year-old boy with intestinal bleeding caused by a large jejunal cavernous hemangioma, which was treated by laparoscopy-assisted resection of the affected portion of the jejunum.

This is a report on the 4 cases of benign mediastinal teratoid tumor in the Department of Thoracic Surgery Chonnam University Hospital during the period from August, 1961 to August ,1972. All the tumors were teratomas which had three germinal layers and located in the anterior mediastinum. All the cases had symptoms such as Pancoast syndrome. exertional dyspnea, middle lobe syndrome with fistulous Connection to the cyst and retrosternal discomfort. X-ray studies are essential to recognize the tumor and its location. It`s believed that a exploratory thoracotomy is recommended because of the complications of the tumors and a possibility of malignancy.

Primary liver tumors are uncommon in childhood, with a relative frequency of 3 % of all childhood tumors. Seventy-three cases of pediatric primary liver tumors operated on at single institution between 1986 and 2002 were reviewed. Malignant tumors included 37 cases of hepatoblastoma, 11 hepatocellular carcinomas, 6 undifferentiated (embryonal) sarcomas, and 1 mixed germ-cell tumor. Benign tumors constitute only 24.6 % of liver tumors, including 7 hemangioendotheliomas, 5 mesenchymal hamartomas, 3 congenital cysts, and one each with focal nodular hyperplasia and hemangioma. The common presenting clinical features were abdominal mass or abdominal distension. Anatomical hepatic resections were carried out in 38 cases, and nonanatomical resections in 34 cases. One patient died of a direct result of hepatic resection (1.4 %). The complication rate was 16.4 %.

Paragangliomas are rare neuroendocrine tumors that are usually benign in nature. They may be either familial or sporadic in their occurrence. Numerous neuroendocrine tumors are collectively included under the umbrella of paragangliomas. Among them, carotid body tumors and glomus jugulare tumors are extremely rare. Thus, we present a rare case of 29-year-old male who was admitted with hearing difficulties and tinnitus in the left ear, with swelling on the left side of the neck. Based on clinical and radiological findings, a diagnosis of left-sided glomus jugulare with carotid body tumor was made. The patient underwent a two-stage surgery with an interval of approximately 2 months. Histopathology revealed a paraganglioma. Herein, we present the clinical features, imaging findings, management, and a brief review of literature on the classification, evaluation, and management of carotid body and glomus jugulare tumors. Paraganglioma is a slow-growing tumor. The synchronous occurrence of carotid body and glomus jugulare tumors is infrequent. Microsurgical resection remains the primary treatment modality. Therefore, our patient underwent two-stage surgery. The rarity of occurrence and the proximity and adherence to vital neurovascular structures have resulted in the treatment of paragangliomas remaining a challenge.

Medical records of 139 tumors from 114 dogs that underwent surgery from May 2010 through March 2015 were retrospectively reviewed. Among 114 dogs, females (64.9%) were significantly more common than males (35.1%) (p<0.05). Dogs aged 6 to 10 years were more presented than non-tumor patients, however, there was no significant difference. The mean age (±SD) was 10.3±3.0 years. Although we found no significant difference of breed predisposition, the most common breed was Maltese (19.3%), followed by Shih-Tzu (14.0%), and Yorkshire terrier (13.2%). Proportional morbidity ratios (PMRs) of mammary gland, oral cavity, and skin tumors were high in Poodles, Yorkshire terriers, and Golden retrievers, respectively. Mammary gland (36.0%) was the most common site, followed by skin and soft tissues (12.2%), oral cavity (10.8%), and digestive organs (8.6%), but there was no significant difference. The objectives of surgery were curative surgery (86.2%), biopsy (4.9%), and palliative surgery (6.5%). In this study, 123 of 139 tumors had histopathological diagnoses. Adenocarcinoma was the most common type (n=24), followed by adenoma (n=17), soft tissue sarcoma (n=13), benign mixed tumor (n=5), and others (n=64). Recurrence or suspected metastasis was identified in 26 dogs. Median survival times of malignant mammary gland tumors, skin and subcutaneous tumors, and splenic tumors were 1,563.0±1,201.7, 469, and 128 days, respectively.

There is a difficulty in complete removal of tumor developing at the parapharyngeal space or infratemporal space where they are just under the skull base. We have experienced 3 cases of malignant tumors and 5 cases of benign tumors arising from the parapharyngeal spaces and/or infratemporal space since 1976. We hereby present 8 cases of primary tumors arising in these spaces with a review of anatomical relationship between above spaces, the characteristic symptoms, diagnostic technics, and surgical approaches which should be considered in their management.
