        (Kyung Tae),이영석(Young Seok Lee),김희옥(Hee Ok Kim),이용섭(Yong Seop Lee) 대한두경부종양학회 2008 대한두경부 종양학회지 Vol.24 No.1

        Adenoid cystic carcinoma(ACC) is one of the common malignant tumor of the major and minor salivary glands. ACC arising from the larynx is relatively rare(less than 1% of laryngeal malignant tumors) and only about eighty cases have been reported in the English literature. Definite diagnosis of these lesions is made only from a histological analysis, because findings and symptoms are non-specific. The diagnosis progresses very slowly, therefore it often presents at an advanced stage with regional and distant metastasis. Here, we present one case of ACC of the supraglottic region with a review of literature.

        (Kyung Tae):민현정(Hyun Jung Min),송미나(Mi Na Song),신광수(Kwang Soo Shin),이승환(Seung Hwan Lee),김경래(Kyung Rae Kim),이형석(Hyung Seok Lee) 대한두경부종양학회 2007 대한두경부 종양학회지 Vol.23 No.1

        Background and Objectives :Supraglottic partial laryngectomy is oncologically sound surgical procedure for selected cases of laryngeal cancer which maintains physiologic speech and swallowing without permanent tra-cheostoma. The purpose of this study is to evaluate the oncologic and functional results of supraglottic partial laryngectomy and neck dissection for supraglottic cancer. Materials and Methods :Between 1991-2005, Twenty-three supraglottic cancer patients, underwent supra-glottic partial laryngectomy, were studied retrospectively. There were 5 patients with cT1, 14 with cT2, 4 with cT3 and 11 patients with cN0, 1 with cN1, 10 with cN2, 1 with cN3. All patients underwent neck dissection and postoperative radiotherapy was added to twenty patients. They were reviewed with respect to primary subsites, extended subsites, treatment result, survival rate, factors affecting the prognosis, postoperative complication, time of decannulation and oral diet, and postoperative voice. Results :Among eleven patients with clinically negative node, six patients had pathologically positive nodes. So occult metastasis was 54.5%. Two patients recurred at cervical lymph node and one had distant metastasis to lung. Local and regional control were 100% and 91.3%. The overall 3-year and 5-year survival rate were 84%, 78%, respectively. Nineteen cases were squamous cell carcinomas and four were basaloid squamous cell carcinomas. Basaloid subtype was significantly affected to survival. Decannulation and oral feeding were possible in 100%. Conclusions :Supraglottic partial laryngectomy is oncologically safe and functionally good procedure in supraglottic cancers. Elective neck dissection is beneficial in management of occult cervical metastasis.

        안유헌(You Hern Ahn),진봉준(Bong Joon Jin),김윤정(Yun Jeong Kim), (Kyung Tae) 대한두경부종양학회 2007 대한두경부 종양학회지 Vol.23 No.2

        Malignant lymphoma of the thyroid gland is a reletively rare and constitute up to 1-5% of all thyroid ma-lignancies. It is known to be frequently associated with Hashimoto’s thyroiditis. The clinical presentation inclu-des an enlarging neck mass, accompanied by dysphagia, hoarseness or tenderness, with its most common his-tologic type being the diffuse large B cell non-Hodgkin’s lymphoma. We have experienced a case of thyroid lymphoma arising from Hasimoto's thyroiditis in a 57-year-old woman, who presented with an anterior neck mass. We present this case with a review of the literature.

        Background and Objectives :Peripheral nerve sheath tumors(PNSTs) are uncommon neoplasm in the head and neck region. The treatment of PNSTs is surgical removal, but excision cause neurologic complications. This study was performed to evaluate the proper diagnosis and treatment of PNSTs with our experiences. Subjects and Method :During the period from October 1994 to July 2007, 58 patients were diagonised with PNSTs in head and neck region. We reviewed medical records and imaging study retrospectively. Result :95%(55/58) of the PNSTs in head and neck were benign;5%(3/58) were malignant peripheral nerve sheath tumors(MPNSTs). 63%(37/58) were neurilemoma, 20%(17/20) were neurofibroma, 2%(1/58) was perineuroma. 55 patients underwent surgery. 80%(45/55) of cases were treated with excision. Enucle-ation was performed in 7(14%) patients. All cases of benign neurogenic tumors showed no recurrence. Among 3 of MPNSTs 2 patients were Von Recklinghausen’s disease and expired with regional recurrence and lung metastasis. Conclusion :The benign PNSTs can be treated with enucleation if possible and observation can be another choice to minimize neurologic sequele.
