CT与B超在腮腺Warthin瘤诊断中应用的比较

目的 :分析腮腺Warthin瘤的CT与超声(ultrasound,US)图像的影像学特征,探讨两种检查结果对腮腺Warthin瘤的诊断价值。方法 :回顾性分析经过病理证实的34例腮腺Warthin瘤CT和超声的影像特点,对病变部位、形态、大小、数目以及CT动脉期、静脉期病灶强化表现进行分析。结果:将CT和US诊断结果与病理结果进行对比,CT检查对腮腺Warthin瘤定性的敏感度为73.5%,US敏感度为38.2%。CT与US检查比较,在显示病灶形态、裂隙样囊变以及边缘小血管显示方面,两者差异有显著性统计学意义(P>0.05),在显示病灶密度/回声均匀及病灶边界方面,两者差异无统计学意义(P<0.05)。结论:超声检查及CT均可作为筛选腮腺Warthin瘤的检查方法,CT检查对于腮腺Warthin瘤的影像学细节显示优于US检查。     

腮腺沃辛瘤62例临床观察

目的:总结腮腺沃辛瘤的临床特点。方法:回顾性分析62例腮腺沃辛瘤患者的资料,分别就年龄、性别、吸烟情况、病变特点及治疗方法予以分析总结。结果:腮腺沃辛瘤好发于老年男性,患者多有明显长期吸烟史,病变多发生于腮腺下极,手术宜采用瘤体及部分腺体切除。结论:该肿瘤特点显著,应正确诊断和治疗。     

超声检查在多形性腺瘤和Warthin瘤鉴别诊断中的应用

目的:回顾性分析腮腺多形性腺瘤与Warthin瘤的超声声像图,总结其声像图特征,为两者的鉴别提供参考。方法:回顾经病理确诊的24例腮腺多形性腺瘤及18例Warthin瘤患者的超声检查结果,分析其声像图表现特征。结果:大多数多形性腺瘤为低回声,回声均匀一致,或呈小分叶状,后方回声增强,周边型血流。而Warthin瘤多呈椭圆形,内部常伴有囊性成分,为内在型血流。结论:腮腺多形性腺瘤与Warthin瘤在声像图上有些相似,容易误诊。超声检查在两者的鉴别诊断中有较高的临床价值,可为临床的治疗及手术方案提供鉴别依据。

Synchronous pleomorphic adenomas of the major salivary glandsA case report

The presentation of multiple distinct tumors in major salivary glands is rare. Although the most common tumor with bilateral synchronous or metachronous development is the Warthin tumor, pleomorphic adenomas have been diagnosed simultaneously as well. We report the case of a female patient who was diagnosed with pleomorphic adenomas in the right parotid and submandibular glands, concomitant with sialolithiasis affecting the submandibular gland. This patient had been exposed to head and neck radiotherapy in childhood, which may have played a role in the development of her tumors. A review of the relevant literature is included.     

Metachronous bilateral pleomorphic adenoma of the parotid gland

Bilateral salivary gland tumors are very rare, accounting for 3% of all parotid gland tumors. Although the most common tumor with bilateral development is the Warthin tumor, pleomorphic adenomas (PA) have been diagnosed simultaneously as well, but in a smaller incidence. Because of this, the prevalence, etiology, pathogenesis, and behavior of the PA in this context are poorly understood. We present a case of bilateral metachronous PA affecting the parotid gland in a 63-year-old woman. Clinically, the lesions presented with similar aspects as seen in cases of solitary PA with slow-growing asymptomatic nodule. Both lesions were diagnosed by fine-needle aspiration biopsy at an interval of 2 years between them. A total and superficial parotidectomy for left and right tumors, respectively, was performed. Only on the left side some facial nerve branches were removed that induced partial paralysis in the patient. A review of the pertinent literature is included.     

腮腺Warthin瘤及瘤旁腺泡细胞增殖与细胞凋亡的定量研究

目的：探讨细胞增殖与细胞凋亡在腮腺Warthin瘤及瘤旁腺泡中的作用。方法：取64例中部分Warthin瘤及瘤旁腺泡作流式细胞术（flow cqtometry,FCM)。以ModFit LT软件进行细胞增殖分析，以Sub-G1法检测凋亡率.结果：Warthin瘤的DNA指数（DNA index ,DI）、S期细胞比例（schizocqto%,S%)、PI增殖指数（proliferation index,PI）与凋亡率分别为1．13、8．83、9．95和8．24,属最高值，瘤旁腺泡的DI、S％、PI和凋亡率分别为1．08、8．94、8．66和6．67。正常腮腺为0．99、5．10、8．01和5．75。三者之间无显著差异（P＞0．05）。结论：腮腺Warthin瘤和瘤旁腺泡的细胞增殖与细胞凋亡水平稍高于正常腺泡，但差异不大，预示该肿瘤术后复发可能性较小。     

两种腮腺肿瘤及瘤旁腺泡细胞增殖与细胞凋亡的比较研究

目的：探讨细胞增殖与细胞凋亡在腮腺多形性腺瘤warthin瘤及其瘤旁腺泡中的变化与作用。方法：取30例腮腺多形性腺瘤、26例腮腺Warthin瘤及其瘤旁腺泡作流式细胞术（flow cytometry,FCM）研究。以ModFit LT软件进行细胞增殖分析,以Sub—G1法检测凋亡率。结果：腮腺多形性腺瘤的增殖指数（PI）与凋亡率分别为14．30和13．41,属最高值,其次是Warthin瘤,PI为9．95,凋亡率为8．24,而多变形性腺瘤瘤旁腺泡PI为9．53,凋亡率为9．56,Warthin瘤瘤旁腺泡PI和凋亡率分别为8．66和6．67,接近正常腺泡的PI和凋亡率（8．01和6．63）。总体上具有统计学意义（P〈0．05）。结论：腮腺多形性腺瘤及瘤旁腺泡PI和凋亡率处于高值,提示其瘤旁腺泡可能处于“准新生物”状态,可能成为肿瘤复发的发源地,而腮腺Warthin瘤及瘤旁腺泡PI和凋亡率接近正常预示着该肿瘤切除后极少复发。     

����Warthin��109���ٴ�����

目的总结腮腺Warthin瘤的临床特点。方法回顾性分析1999年1月至2008年12月内蒙古医学院第一附属医院和内蒙古自治区人民医院口腔科收治的109例腮腺Warthin瘤患者的病历资料,分别就年龄、性别、吸烟史、多发性及治疗方法予以分析总结。结果 109例Warthin瘤中男女比例约5.8:1,50～70岁为发病年龄高峰,其中单发病例数明显多于多发。吸烟患者男性明显多于女性。结论腮腺Warthin瘤临床特点显著,手术治疗治愈率高,术式选择可根据实际情况决定。     

False diagnosis caused by Warthin tumor of the parotid gland combined with actinomycosis

A case is reported in which a unilateral parotid gland cystadenolymphoma was combined with actinomycosis. A 48-year-old woman presented with a mass in the left parotid region and paresis of the lower left palpebra. The computed tomography, echography, and parotid radiographic findings did not exclude a neoplasm of the left parotid gland. The ramus of the mandible was involved in the process. Intraoperative freezing histology, total parotidectomy, and partial mandibulectomy were performed, with sacrifice of the facial nerve followed by nerve reconstruction. The final histological evaluation was Warthin tumor with actinomycosis. Four years after treatment, the patient is free of disease. No similar cases seem to have been reported thus far.     

Warthin tumor arising from the minor salivary gland

ABSTRACT: Warthin tumor (WT) accounts for 4% to 13% of all salivary gland tumors. This benign tumor, which commonly arises in the parotid gland, is the second most common tumor of the salivary gland. WT is multicentric in 12% to 20% of patients and is bilateral in 5% to 14%. The mean age at diagnosis is 62 years (range, 12-92 years), and it rarely presents (<6%) before age 40 years. Extraparotid WT, arising from the submandibular gland or cervical lymph node for example, is very infrequent, with corresponding incidences of 0.4% to 6.9% and 8%, respectively. Moreover, WT arising from the minor salivary gland is extremely rare, with a reported incidence of merely 0.1% to 1.2%. We report here WT arising from the minor salivary gland in the buccal mucosa in a 66-year-old woman and review cases of WT of the minor salivary gland reported in the English literature.     

Parotid gland tumors in a Korean population

Salivary gland tumors occur in about 3% of the head and neck tumors, and among the salivary gland tumors, parotid gland tumor occurs in about 80%. Because of its low frequency and small cases, it is hard to establish the epidemiologic characteristics of the tumors. This study was performed retrospectively from February 1987 to August 2010. There were 95 male, and 76 female patients. Most of the patients complained of the painless and progressively enlarged mass in the preauricular area. Peak incidence of benign parotid gland tumor was at the fifth decade of life. In the malignant tumors, peak age in males was the eighth decade, and peak age in females was from the third to the fifth decade of life, which was relatively younger and has a broad range of spectrum. Pleomorphic adenoma was the most common benign tumor of the 93 cases (61.6%) followed by Warthin tumor, occurring in 20 cases (13.2%). Squamous cell carcinoma, reported in 6 cases (30%), is the most frequent. Mucoepidermoid carcinoma was the second leading tumor. In conclusion, parotid gland tumor incidence was found to be higher in males. Pleomorphic adenoma was the most commonly encountered type of parotid gland neoplasms, which is in agreement with findings from all of the published literature from all over world. In contrast to most of the previous studies, squamous cell carcinoma was the most frequent malignant tumor found. Based on the data in this study, it has significant clinical respect and is helpful in the management of parotid gland tumors in Orientals.     

Unilateral agenesis of the parotid gland: a case report

Agenesis of the parotid gland is an extremely rare condition and may be partial or total, unilateral or bilateral, and may occur on its own or associated with other developmental abnormalities. We report a case of unilateral agenesis of the parotid gland without involvement of other major salivary glands together with a compensatory hypertrophy of the contralateral parotid gland.     

Malignant mixed salivary tumor presenting as a mandibular metastasis

A rare case of a central mandibular metastatic mixed salivary gland tumor is reported which presented following a 45-year history of recurrent benign mixed salivary gland tumor of the parotid gland on the same side. The mandibular tumor included a predominantly benign mixed salivary gland component as well as frankly invasive adenocarcinoma. The clinicopathologic features of the mandibular and residual parotid tumors suggested that the metastatic event may have occurred prior to the development of frank carcinoma in the parotid tumor.
