Subglottic laryngeal paraganglioma

OBJECTIVES: To review the clinical and pathological picture of laryngeal paragangliomas and compare laryngeal paragangliomas with the three other types of laryngeal neuroendocrine neoplasms. STUDY DESIGN: The study presents a case review of a patient with a subglottic laryngeal paraganglioma treated at our institution, with a literature review of the laryngeal neuroendocrine neoplasms. Included is a review of all four neuroendocrine neoplasms, taking a close look at a comparison between laryngeal paragangliomas and atypical carcinoids tumors. All cases of subglottic laryngeal paragangliomas reported in the literature were also compiled and tabulated. METHODS: The patient's record was reviewed for age, symptomatology, workup, and surgical procedures performed. RESULTS: The patient was disease free 36 months after undergoing a tracheostomy for airway control, followed by a cricoid split for complete excision of the tumor. CONCLUSIONS: It is important to differentiate among the four laryngeal neuroendocrine neoplasms, especially between atypical carcinoids and paragangliomas. Each tumor requires different treatments, with the former requiring a more aggressive approach. Paragangliomas must be completely excised to prevent their recurrence, and this approach should be considered a curative treatment. In addition, the immunohistochemical battery is of paramount importance in obtaining the correct pathological diagnosis.     

Laser in treatment of laryngeal amyloidosis

Amayloidosis is the extracellular deposition of the fibrinous protein amyloid in one or more body sites. Amyloidosis may broadly be classifed as either primary or secondary. Primary amyloidosis is idiopathic (56 %), whereas the secondary form is associated with a chronic inflammatory or infectious process (5%). Amyloidosis is also related to multiple myeloma (26%), senescence (5%) and where tumor like deposits occur in isolated organ without systemic involvement (8%). Laryngeal amyloidosis is a rare disease. Surgery has been the mainstay of treatment either endoscopicalfy or by an external neck approach. One case of laryngeal amyloidosis, treated with endolaryngeal microsurgery and carbon dioxide laser is presented with a follow up of 8 years.     

A clinico-pathological classification of laryngeal paraganglioma.

A case of metastatic laryngeal paraganglioma is presented. We have reviewed the current world literature on this entity and thereby identified two apparently distinct types of this rare lesion (type I and type II). The histopathological features are unhelpful in discriminating these two types and this is instead based on clinico-epidemiological differences. The latter are annotated and discussed with respect to prognosis and management. A true estimate of the frequence of type II (potentially malignant) awaits the utilization of the recent improvements in diagnostic techniques.     

Combined treatment of embolization followed by surgical resection in carotid paraganglioma

Carotid body tumors represent a relatively uncommon finding in vascular surgery. We present the case of a 62 years old man with a right carotid paraganglioma diagnosed by cervical ultrasound scanner, magnetic resonance imaging and carotid arteriography. We decided to treat the patient in two times. In a first approach the tumor was percutaneously embolized, later on in a second time the paraganglioma was surgically resected. The patient is doing well without echographic evidence of tumor 3 years after the operation. This modality of treatment, embolization followed by surgical excision is a useful and valuable alternative.     

喉癌功能保全性手术

本文对我国近十年来在喉癌外科治疗方面的进展进行了回顾。喉癌的外科治疗在根治肿瘤的前提下,喉功能的保留越来越受到重视。现代头颈外科技术的发展,要求术前和术中准确地判断肿瘤的部位和范围,术中根据肿瘤切除后喉部的缺损情况,采用不同方法进行修复和重建,以恢复喉的三大功能。实践证明只要正确掌握手术适应证,在相当一部分喉癌病例,喉部分切除术不但可以取得与喉全切除术相同的疗效,而且可保留喉的功能,提高患者的生存质量。     

保留喉功能的T3期声门上喉癌的手术治疗

目的：探讨T3期声门上喉癌喉功能保留手术的可行性、技术操作和临床疗效。方法：回顾性分析1994～2003年收治的T3期声门上癌70例，均行喉功能保留手术，其中喉声门上水平部分切除术42例，喉声门上水平垂直部分切除术19例，喉环状软骨上部分切除术8例，喉近全切除术1例。以胸骨舌骨肌肌筋膜瓣、颈阔肌肌皮瓣、双蒂接力肌甲状软骨膜瓣、甲状软骨膜瓣等修复喉腔组织缺损，重建喉功能。全部患者均接受术后放疗（剂量50～60Gy）。结果：3年生存率为79．2％，5年生存率为68．4％。70例患者中已拔管60例，拔管率为85．7％。全部患者均恢复经口进食，无明显呛咳及吞咽困难。所有患者均发声成功，无一例因喉腔闭锁而致发声失败。结论：T3期声门上癌虽属晚期喉癌，但只要严格掌握适应证，熟练运用多种修复方法，提高外科手术技巧，保留喉功能是可行的。

A case of paraganglioma of the recurrent laryngeal nerve

Paragangliomas are rare neuroendocrine tumors that derive from the extra-adrenal paraganglia. In the head and neck region, these neoplasms most commonly arise from the carotid body, the vagus nerve, and the jugulotympanic area. We describe the case of an 87-year-old woman with an incidental finding of a clinically, radiologically, and cytologically presumed retrosternal goiter. During a left thyroid lobectomy, she was found to have a mass that originated in the left recurrent laryngeal nerve. The mass was resected, and subsequent histopathologic examination found it to be a paraganglioma. Follow-up evaluation confirmed the expected finding of a left-sided vocal fold palsy. To the best of our knowledge, this is the first reported case of a paraganglioma arising from a recurrent laryngeal nerve.

Effect of surgical treatment on lymphoproliferation in advanced supraglottic laryngeal cancer

OBJECTIVES: The capacity of cell immunity to act against tumor cells has been presented as a decisive influence in the prognosis of patients with cancer. The aim of this study was to evaluate lymphoproliferation in nonadherent peripheral blood cell cultures of patients with advanced supraglottic laryngeal cancer. STUDY DESIGN: Fourteen patients with advanced supraglottic laryngeal cancer were studied prospectively. Lymphoproliferation was quantified by adding 3H-thymidine and measured in counts/minute using liquid scintillation spectrometry. Based on the ratio between stimulated and baseline cultures, the proliferation index was calculated before and 236 +/- 18 days after the surgery. RESULTS: Lymphoproliferation was lower in patients than in healthy controls (P = .01) in the preoperative as well as in the late postoperative period (P = .006 and P = .02, respectively). However, there was no change from preoperative to late postoperative. CONCLUSION: Pre- and postoperative results show that patients with advanced supraglottic laryngeal cancer present lymphoproliferation diminished before the surgery, and in the late postoperative period, there was no recovery of immune capacity evaluated by lymphoproliferation measurement.
