Gastric cancer is the most common cancer in Korean males and can easily spread to distant organs such as the liver, lungs, brain, or bones. However, skin metastasis, particularly of the eye, is rare. Metastatic eyelid cancer is extremely rare; metastases from internal organs have not been reported so far. We recently experienced a patient with metastatic eyelid cancer from adenocarcinoma of the stomach. A 62-year-old female was admitted with a right upper eyelid mass and foreign body sensation. She had a history of stomach cancer of 3 years. She was treated by chemotherapy and radiotherapy for pathologic fracture. After receiving supportive care for 2 years, the mass appeared on her right pupil. Punch-biopsy of the mass was performed and histological examination revealed adenocarcinoma, the same as the initial histological result. We report this case with a review of related literature.

Choristoma is a growth of normal tissue that occurs at an abnormal region. In the oral cavity, osseous choristoma that has a normal bone feature mainly has been appeared. It is mainly occurred on the tongue. So, It can be found in dental practice or in discomfort in the mouth. Osseous choristoma in the oral cavity is extremely rare. But It can be treated excisional biopsy under local anesthesia. The prognosis is very good. This case is a report of osseous choristoma on the dorsal surface of the tongue. A 17-year-old female patient presented with a foreign body sensation of the tongue. A diameter of the mass is 0.7cm, and there is no pain. Panoramic radiographs showed a radiopaque image in the form of a double image. An excisional biopsy was performed and diagnosed as an osseous choristoma. 12 months after the resection, there were no signs of recurrence. Intraoral osseous choristoma is very rare, but it is clinically very simple and can be found in dental radiographs. We present this case because of Dentists who examine the oral cavity of the patient can easily diagnose the lesion and treat it by simple resection.

A lingual thyroglossal duct cyst(LTGDC) is a rare congenital anomaly that account for only 0.5% to 2% of total thyroglossal duct cyst. LTGDC is frequently associated with respiratory problem in infants and pharyngeal foreign body sensation or dysphagia in adults. Because of its location and characteristics, lingual thyroid, dermoid cyst, and vallecular cyst should be included in differential diagnosis. Standard treatment for thyroglossal duct cyst is sistrunk's operation, but in terms of LTGDC, because of its location and cosmetic reasons, different kinds of treatments such as electrical cauterization, $CO_2$ laser, Robort surgery via transoral approach have been introduced. Recently authors encountered 21 years old woman with LTGDC and the mass was removed successfully via transoral approach using $CO_2$ laser. We report the clinical course with review of the literature.

Bronchogenic cysts are congenital malformations of the bronchial tree, a type of bronchopulmonary foregut malformation. The presentation of the bronchogenic cyst is variable, making pre-operative diagnosis difficult. They aremostly asymptomatic orarefound incidentally when the chest is imaged. They can present as lower neck massesor mediastinal masses that may enlarge. They cause mass effect due to local compression and may result in tracheo-bronchial obstruction leading to air trapping and respiratory distress. The treatment is somewhat controversial, and in general,these lesions are treated using the transcervical or transbronchial approach. When these cysts arelocalized in the upper mediastinum, it may be possible to removethemusing the transcervical approach. In our three cases, the patientscomplained of mild dysphagia, foreign body sensation, and dyspnea. We report three cases of a large bronchogenic cyst in the lower neck and the upper mediastinum treated using the transcervical approach.

Background: Conventionally, indirect radiography has been used to diagnose salivary gland diseases. However, with the development of sialendoscopy, diagnosis and treatment of salivary gland diseases have become more effective. Herein, we report a case of sialolithotomy treated with sialendoscopy and compare it with the existing methods through a literature review. Case presentation: Two patients with a foreign body sensation under the tongue and dry mouth visited the Anam Hospital, Korea University. Radiographic examination revealed salivary stones inside the right Wharton duct, and the patients underwent sialolithotomy under local or general anaesthesia. The stones were totally removed, and there were no postoperative complications such as bleeding or pain. Conclusion: The development of sialendoscopy has enabled better definitive diagnosis of salivary gland diseases compared with the conventional methods; better treatment outcomes can be obtained when sialendoscopy is used in appropriate cases.

Rheumatoid arthritis (RA) is a connective tissue disease involving the larynx in 30 % of the patients. Foreign body sensation, hoarseness, and cough are common symptoms in laryngeal involvement. An urgent tracheostomy is required when acute airway obstruction occurs in case of bilateral vocal fold paralysis. The most common cause of bilateral vocal fold paralysis in RA patients is a cricoarytenoid joint arthritis. Laryngeal nerve degeneration is rare cause of bilateral vocal fold paralysis in RA patients. In this case report, an emergent tracheostomy was performed on a 64-years-old male patient with acute dyspnea, and concurrent involvement of RA on laryngeal nerve and cricoarytenoid joint was revealed by laryngeal electromyography and histopathology. The vocal fold mobility was restored after 3-months medical treatment.

Ophthalmomyiasis rarely occurs worldwide, and has not been reported in Korea. We present here a case of ophthalmomyiasis caused by Phormia sp. fly larva in an enucleated eye of a patient. In June 2010, a 50-year-old man was admitted to Dankook University Hospital for surgical excision of a malignant melanoma located in the right auricular area. He had a clinical history of enucleation of his right eye due to squamous cell carcinoma 5 years ago. During hospitalization, foreign body sensation developed in his right eye, and close examination revealed a fly larva inside the eye, which was evacuated. The larva was proved to be Phormia sp. based on the morphology of the posterior spiracle. Subsequently, no larva was found, and the postoperative course was uneventful without any complaints of further myiasis. This is the first case of ophthalmomyiasis among the literature in Korea, and also the first myiasis case caused by Phormia sp. in Korea.

Purpose: In case of facial injury, a canalicular injury is common. Many methods and materials have been used for reconstruction of lacrimal canaliculi. Silicone tube is the most widely used material, generally with pigtail probe or stainless steel probe. But it has still many problems. The authors guess that reconstruction using Mini $Monoka^{(R)}$ will reduce those problems and will be more successful. Methods: From July, 2003 to November, 2006 in 24 patients with canalicular injury, 11 cases were recon- structed with former silicone tube and 13 cases were treated with Mini $Monoka^{(R)}$. Results: The mean follow-up period was 3 months. The results of reconstruction were classified into three groups(Normal, Fair, Poor). In 13 cases with Mini $Monoka^{(R)}$ stent, 10 cases were normal, 3 were fair, and no poor cases. But in 11 cases with bicanaliculus silicone stent, 6 cases were normal, 3 were fair, and 2 were poor. Conclusion: Compared with bicanaliculus silicone stent, Mini $Monoka^{(R)}$ stent is fixed well, has no aesthetic problems, makes less foreign body sensation. And the results were successful.

Introduction : Laryngomicrosurgery(LMS) is frequent procedure applying to benign and early malignant larygeal disease such as vocal cord polyp, nodule and early glottic cancer. LMS has been known as safe procedure and short time consuming treatment. So few reports about complications in LMS was done. In this study, complications and problems from LMS were investigated and reported. Method : From 2000, January to 2001, December, 180 patients who were treated with LMS in Asan medical center were studied by retrograde chart review. Results : In these patients, total 9 patients(5%) were suffered from complication. 4 patients (2%) had teeth injury and 4(2%) were suffered from foreign body sensation in tongue and 1(1%) had hypoglossal nerve injury. Main mechanism of complications is thought by pressure injury by laryngoscope blade. No definite correlation between procedure and complication was observed. Conclusion : There are few neural complications with LMS such as lingual and hypoglossal nerve injury. Before operation of LMS, warning and informing of complications by mechanical stress must be done. Gentle procedure and short operation time are necessary to avoid these problems. And patients who have risk factors of oral complications such as dental disease or dental prosthesis must have dental evaluation and treatment before LMS procedure.

Historically, Eagle syndrome is a term that has been used to describe radiating pain in the orofacial region, foreign body sensation, and/or dysphagia due to a unilateral or bilateral elongated styloid process impinging upon the tonsillar region. Because elongated styloid processes-with or without associated Eagle syndrome-can present with various symptoms and radiographic findings, it can be challenging for healthcare practitioners to formulate an accurate diagnosis. Abnormal styloid anatomy can lead to a multitude of symptoms, including chronic orofacial/neck pain, thus masquerading as more commonly diagnosed conditions. In this report, we describe a patient who presented to our department with styloid process elongation and fracture. A careful history, physical examination, and a cone-beam computed tomography (CBCT) investigation led to the diagnosis. The patient was then referred for appropriate care. This case report demonstrates the utilization of CBCT in differentiating a fracture site from a pseudo-joint that might mimic a fracture.
