The clinicopathologic characteristics, treatments and prognosis of retinoblastoma, the most common intraocular tumor in children, were studied retrospectively in 101 cases(128eyes) who visited our clinic from 1987 to 1996. All patients were followed for 2 years or longer. Twenty seven cases were bilateral and seventy four cases were unilateral,. Eihgty four eyes were enucleated. Twenty one eyes were successfully treated by conservative modality. The rest refused any type of treatment. Orbital recurrence or distant metastasis were observed in 5 cases after enucleation without systemic treatment, and one died in spite of irradiation and aggressive chemotherapy. It is widely recognized that the prognosis for survival of retinoblastoma patients, especially unilateral, is excellent, however the authors emphasize the importance of careful postoperative histopathologic review and long term periodic follow-up to improve long-term prognosis.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most useful diagnostic tool in biliary and pancreatic disease. However, ERCP cannot be performed successfully in all patients. Cannulation failure is the most common cause of failure of ERCP. Mechanical pathologies, such as peri-Vater diverticulum, cancer of the papilla of Vater, and impacted stone were the common causes of cannulation failure. We experienced two cases of carcinoma of the papilla of Vater in whom cholangiography and insertion of the nasobiliary tube were performed througth an artificial choledoehoduodenal fistula made by a needle type diathermy knife, beacuse cannulation to the duct was failed due to the tumor.

Thymic cyst is relatively rare tumor which usually occurs in the neck or mediastinum. Cervical thymic cyst is usually situated laterally and deep to the anterior border of the sternocleidomastoid muscle, simulating a branchial cyst. Thymic cyst of the mediastinum is usually detected incidentally and differential diagnoses include cystic degeneration of thymoma, and cystic teratoma. Two case of a cervical and a mediastinal thymic cysts were reported. The one was a cervical thymic cyst developed slowly growing mass in a 53-year-old male a for 10 years. The cyst was unilocular and measures 5.4x2.9x2.8 cm with columnar or squamous cell linings. The other is a mediastinal thymic cyst developed in a 37-year-old female with chest discomfort for 7 months. The cyst was uniocular and measures 2.8x2.2x2.0 cm. The epithelial lining of the cyst was largely desquamated and covered by macrophages with cholesterol granuloma. Involutional thymic stissue in their walls were noted in both cysts. In both cases presence of thymic tissue in the wall of the cyst thought to be the most important diagnostic feature.

Leiomyoblastoma is uncommon and has been known as a neoplasm of smooth muscle origin. However, with recent pragress in immunohistochemical staining techniques, many clinicopathological discrepancies have been pointed out about the origin of leiomyoblastoma. We present here a case of gastric leiomyoblastoma did not expressed desmin and neuron specific enolase, and was thought to be of unknown derivation.
