  • The worm of Thelazia callipaeda Railliet et Henry, 1910 (The oriental eye worm) was frequently observed in the eyes of animal and human in Korea. But it did not clearly describe about the ultrastructural character on the sensory papillae and cuticular striation of the worm. This study was performed to investigate the ultrastructure and character on the cuticular surface of the worm that was extracted from the eyes of two patients in Korea University Medical Center, using the scanning electron microscopy. According to the mouth, 1/4, 1/2, 3/4 and tail portion of the worm, the size of cuticular striation on each portion was measured. The size of cuticular striation on the worm surface was $1.8{\mu}m$ in the mouth and tail portion, $4.0{\sim}4.5{\mu}m$ in the middle portion of the worm. On the scanning electron microscopy, the female worms were developed phasmids in the tail end and male worms were developed sensory papillae and external sexual organ on the tail end. The sensory papillae on the tail end were composed anterior ventral postcloacal papillae, middle ventral postcloacal papillae, subventral postcloacal papillae, and lateral papillae. According to the result in this study, it is considered that the character of the cuticular striation and the sensory papillae were able to accept as classifying key for the identification of species.

  • Neurilemmoma is a benign tumor which arises generally from the Schwann's cells. It is a slowly growing tumor and treated as surgically. We experienced a case of neurilemmoma of the oropharynx in a 28-year-old female who had noticed a gradual swelling of the left side of the oropharynx with swallowing difficulty for 6 months. The tumor was removed successfully intra-orally under the general endotracheal anesthesia and verified pathologically as neurilemmoma.

  • 1972년 Jako와 Strong이 후두질환에 $CO_2$레이저 사용을 발표한 이래 최근 이비인후과영역에서 $CO_2$레이저를 이용한 수술방법이 각광을 받고 있으며 특히 후두 및 기관지 협착증에서의 $CO_2$레이저 이용은 현재까지 가장 좋은 방법의 하나로 소개되고 있다. 이와 더불어 최근 레이저를 이용한 기관지경술이 이용되고 있는데, 이는 기관 및 기관지의 여러 질환중에서 유두종등의 양성종양의 제거, 기관 및 기관지 협착증의 치료, 그리고 원발 혹은 전이에 의한 기관내 악성종양의 고식수술(姑息手術)등에 이용되고 있다. 최근 저자들은 성문하부 및 기관내에 발생한 후두 및 기관유두종 2례와 육아조직에 의한 성문하부 및 기관협착증 2례에서 coherent $CO_2$레이저 기관지경을 이용한 기관지경술로 만족할 만한 결과를 얻었기에 문헌고찰과 함께 보고하는 바이다.

  • Recurrent respiratory papillomatosis (RRP) is characterized by repeated recurrence in the respiratory system, such as the pharynx, larynx, and trachea, caused by the human papilloma virus. The main treatment is surgical removal of the papilloma. However repeated recurrence of RRP in multiple areas is burdened for the surgeon. In addition to the surgery, various adjuvant therapies have been studied to reduce the recurrence. Literature review was conducted with a focus on the adjuvant treatments for RRP.

  • Papillary fibroelastoma is a rare benign tumor of the heart. A 21-year-old man presented with dyspnea on exertion and echocardiogram showed a small round mass attached to the anterolateral papillary muscle. After excision of the mass, including anterior papillary muscle, chordae tendinae, and anterior leaflet, he underwent mitral valve re-placement with a mechanical valve. He was discharged on anticoagulant therapy without further problems.

  • Bronchial papilloma is a rare disease which most commonly manifests as an epithelial tumor consisting of polypoid interstitial tissues and epithelioid cells. This benign tumor comprises 2-5% of primary lung tumors and papilloma derived from the bronchial epithelium, and is a rare benign tumor in adults. Bronchial papilloma has a poor prognosis with a high risk of developing a malignancy. We report a case of a bronchial papilloma in a 62-year-old female patient, presenting with hemoptysis and an endobronchial lesion with a brief review of the relevant literature.

  • A 59-year-old woman was admintted to the hospital because of intermittent fever and right side chest pain. She has a same episode eight months before this entry. Chest CT scan demonstrated ill-defined parenchymal consolidation containing dilated bronchi of right lower lung field, but no endobronchial mass in the bronchial trees. Fiberoptic bronchoscopy seeking the cause of recurrent pneumonia revealed a small, round mass nearly completely obstructing me lumen of basal segmental bronchus of right lower lobe. The diagnosis of bronchiolar papilloma was made from the biopsy specimens of the bronchoscopic examination. The patient was treated with right lower lobectomy because of irreversible secondary changes below the obstructed bronchus. This thoracotomic excision resulted in complete relief of symptoms and the postoperative course was uneventful for 12 months. Here we report a extremely rare umor with a brief review of literatures.

  • In contrast to juvenile laryngeal papillomatosis, which occurs most often in children and teenagers and is usually self limited, soliatry papillomas in adults are one of uncommon tumors of airway, and have a higher incidence of cancer. They are caused by the respiratory infection of human papilloma virus(HPV). They could spread to more distal airways and have a tendency of recurrence after limited surgical excision. Recently endoscopic therapies such as Nd-YAG laser, electrocautery, and cryotherapy provide extremely effective treatment modalities. We report a case of solitary tracheal papillomas in a 48 year-old man who presented with cough, scanty hemoptysis, and functional evidence of central airway obstruction. He was successfully treated by a Nd-YAG laser therapy via fiberoptic bronchoscopy under the local anesthesia.

  • It is well known that laryngeal papilloma is histopathological benign, but clinically one of the most troublesome disease in otolaryngologic department, usually seen in child age. Since Cleesmann reported papilloma of the vocal cord, 1817 first, the etiology had not been known exactly. The symptoms in children are dyspnea, dysphonia due to recurrence, and papilloma in adult can change into neoplasm. The papilloma is thought as real neoplastic lesion and there is not effective treatment, using now repeated removal and combined therapy. This report is based on the typical findings and progress of one case of laryngeal papilloma observed for the past 13 years with repeated removal and topical application of 5-FU at our department. Authors have experienced this subject is interesting that the change of the tumor region during the course than to any new therapeutic methods employed, and so report with some reviews of the literatures.
