Abstract
Background: Although the expression of tight junction protein claudins (CLDNs) is well known in common histological subtypes of lung cancer, it has not been investigated in rare lung cancers. The aim of our study was to examine the expression of different CLDNs in pulmonary salivary gland tumors. Methods: 35 rare lung cancers including pathologically confirmed 12 adenoid cystic carcinomas (ACCs) and 23 mucoepidermoid carcinomas (MECs) were collected retrospectively. Immunohistochemical (IHC) staining was performed on formalin fixed paraffin embedded (FFPE) tumor tissues, and CLDN1, -2, -3, -4, -5, -7, and -18 protein expressions were analyzed. The levels of immunopositivity were determined with H-score. Certain pathological characteristics of ACC and MEC samples (tumor grade, presence of necrosis, presence of blood vessel infiltration, and degree of lymphoid infiltration) were also analyzed. Results: CLDN overexpression was observed in both tumor types, especially in CLDN2, -7, and -18 IHC. Markedly different patterns of CLDN expression were found for ACC and MEC tumors, especially for CLDN1, -2, -4, and -7, although none of these trends remained significant after correction for multiple testing. Positive correlations between expressions of CLDN2 and -5, CLDN3 and -4, and CLDN5 and -18 were also demonstrated. Tumors of never-smokers presented lower levels of CLDN18 than tumors of current smokers (p-value: 0.003). Conclusion: This is the first study to comprehensively describe the expression of different CLDNs in lung ACC and MEC. Overexpression of certain CLDNs may pave the way for targeted anti-claudin therapy in these rare histological subtypes of lung cancer.

Abstract
INTRODUCTION Mucoepidermoid tumours (TME) are rare tumours arising from the submucosal glands of the tracheobronchial tree. The majority of these tumours develop in a benign fashion but some of them are malignant. The latter can be easily mistaken for adenosquamous carcinomas. PATIENTS AND METHOD We have reviewed 22 patients suffering from TME observed over a period of 25 years. Two arose from the trachea and 20 from the cartilaginous bronchi; 12 of these tumours had macroscopic and histological criteria of low-grade malignancy, 4 had macroscopic and 6 macroscopic and microscopic criteria of high grade malignancy. RESULTS Prognosis of the latter was very poor and no survival observed after 6 years follow-up, a behavior similar to that observed in non-small cell lung carcinomas and adenosquamous carcinomas. CONCLUSION The best treatment of these orphan tumours remains surgery.

Abstract
Stem cells contribute to regeneration of tissues and organs. Cells with stem cell-like properties have been identified in tumors from a variety of origins, but to our knowledge there are yet no reports on tumor-related stem cells in the human upper respiratory tract. In the present study, we show that a tracheal mucoepidermoid tumor biopsy obtained from a 6 year-old patient contained a subpopulation of cells with morphology, clonogenicity and surface markers that overlapped with bone marrow mesenchymal stromal cells (BM-MSCs). These cells, designated as MEi (mesenchymal stem cell-like mucoepidermoid tumor) cells, could be differentiated towards mesenchymal lineages both with and without induction, and formed spheroids in vitro. The MEi cells shared several multipotent characteristics with BM-MSCs. However, they displayed differences to BM-MSCs in growth kinectics and gene expression profiles relating to cancer pathways and tube development. Despite this, the MEi cells did not possess in vivo tumor-initiating capacity, as proven by the absence of growth in situ after localized injection in immunocompromised mice. Our results provide an initial characterization of benign tracheal cancer-derived niche cells. We believe that this report could be of importance to further understand tracheal cancer initiation and progression as well as therapeutic development.

Abstract
UNLABELLED Bronchial mucoepidermoid tumors are uncommon neoplasms, morphologically similar to their salivary gland counterpart. The histogenesis is controversial. The aim of this study is to identify myoepithelial cells and speculate on their role in the origin of these tumors. METHODS AND RESULTS Sixteen bronchial mucoepidermoid tumor surgical specimens were formalin-fixed, paraffin-embedded and studied using a panel of nine antibodies in order to identify a myoepithelial differentiation. Additional antigens against several cytokeratins were performed in four cases and five of the biopies were studied using the electron microscopy. The different types of cells of the primary bronchial mucoepidermoid tumor (mucous luminal, intermediate and squamous) reacted strongly against AE1, CK7, 34bE12 and weakly with AE3, CK18 and CK8/18/19. S-100, alpha-smooth muscle actin, muscle actin HHF35 and alpha-actinin were consistently negative in all cell types. CD10 was positive in very few cells in just one case. CONCLUSION The immunohistochemical and the ultrastructural study of bronchial mucoepidermiod tumors support a ductal unit origin, without a myoepithelial participation.

Abstract
BACKGROUND Alteration of cadherin and catenin expression is associated with loss of differentiation, acquisition of an invasive phenotype, and poor prognosis in many types of cancers. The roles of cadherins and catenins in mucoepidermoid carcinoma (MEC) are not fully understood. METHODS Based on immunohistochemical studies, the expressions of E-, N-, and P-cadherins and alpha-, beta-, and gamma-catenins in MEC were investigated, and correlations with clinicopathologic parameters were evaluated. RESULTS These six molecules were strongly expressed in normal ductal epithelium but increased or decreased immunoreactivities of those proteins in MEC were frequently observed, especially for E-cadherin and alpha-catenin. The immunoactivity of beta-catenin showed significant correlation with grade (P = 0.05) and stage (P < 0.0001). beta-Catenin expressions are also correlated with gamma-catenin expression (P = 0.006) according to cross-table analysis. Survival analysis indicated that stage, grade, and beta-catenin expressions had significant correlation with survival. CONCLUSION Aberrant beta-catenin expression may play an important role in the histologic differentiation and tumor staging of MEC.

Abstract
Laryngeal manifestations of malignant sialogenic neoplasias are rare. This paper documents the clinical features, treatment, biological behaviour and prognosis of 15 cases of malignant sialogenic tumours of the larynx that were reviewed in a retrospective clinical and histopathological study. The 15 cases of malignant sialogenic tumours of the larynx were diagnosed at the University Hospital, Eppendorf, over a period of 33 years (1965-1998). Forty per cent were adenoid cystic carcinomas, 33 per cent mucoepidermoid carcinomas and 27 per cent were poorly differentiated adenocarcinomas. Local tumour resection, if necessary in combination with bilateral neck dissection and post-operative radiotherapy, was associated with a five-year survival rate in 80 per cent of the mucoepidermoid carcinoma cases. Adenoid cystic carcinoma was associated with a less favourable five-year survival rate of 33 per cent. Low-differentiated adenocarcinomas were associated with the least favourable prognosis with a five-year survival rate (25 per cent). The prognosis for these tumours is thus poorer than for squamous cell carcinomas with the same localization and TNM status.

Abstract
Childhood bronchial mucoepidermoid tumours (BMET) are rare. A 12-year-old boy with hepatosplenomegaly underwent liver biopsy which diagnosed amyloidosis. Chest radiograph and CT, performed for recurrent respiratory symptoms, identified a left lower lobe tumour, which was subsequently excised. Histology showed a BMET. A literature review reveals 51 reported cases of BMET in children. Common presenting symptoms include fever, cough and recurrent pneumonia. Diagnosis is often delayed and patients with recurrent respiratory symptoms should undergo CT or bronchoscopy. The association between amyloidosis and BMET in this case is unique and has not been previously described, but may be coincidental.

Abstract
OBJECTIVE Pulmonary mucoepidermoid tumors are commonly included with adenoid cystic carcinoma and carcinoid tumors under the misleading rubric 'bronchial adenomas'. These neoplasms are extremely rare and little is known about their oncologic behaviour. They are considered to be of high, or low malignancy. METHODS During a 16-year-period 34 consecutive patients (24 male and 10 female with an average age of 53 years) underwent surgery for pulmonary mucoepidermoids in our clinic (0.5% of all resected lung tumors). Fourteen patients were complaint free, in the others obstructive symptoms dominated. In 23 patients the tumors were located in the upper lobes. In 24 cases lobectomy, in four instances limited resection and in six cases pneumonectomy were performed without hospital mortality. RESULTS Twenty-nine tumors proved to be high grade and five low grade malignancy by histology. In the latest group the 5-year-survival amounted to 80% (all of these tumors were observed in stage T1-2 N0), on the other hand, however, that rate accounted only 31% at high grade malignant mucoepidermoids. There was no 5-year-survivor among patients having N2-disease (n=5). CONCLUSION Mucoepidermoid tumors have to be treated by radical surgery with lymph node sampling and dissection. Patients with low grade tumors can be expected to be cured following complete resection, on the other hand, however, in cases of high grade malignant neoplasms surgery results in significantly worse prognosis. Careful histological typing plays a key role in prediction of late results.

Abstract
We report a case of low-grade malignant mucoepidermoid bronchial tumor in a 21-year-old woman who presented with hemoptysis. There was a striking radiological presentation with a unilateral clear radiograph. Lung scintigraphy demonstrated perturbed ventilation and perfusion of the left lung. Pulmonary angiography only showed diminished peripheral vascularization. The main vessels were clear. These anomalies fit the radiological category of air trapping accompanied by probably hypoxic pulmonary vasoconstriction. Mucoepidermoid tumors account for only 0.5-1% of all primary lung tumors. They are found in adults as well as in children. There are two clear-cut histological forms with very different prognosis. The tumors of high-grade malignancy are considered as undifferentiated carcinomas and should be treated as such. The prognosis is much better for tumors of low-grade malignancy and current treatment is surgical in the absence of recurrence after isolated endoscopic treatment.

Abstract
Mucoepidermoid tumours (TME) are rare tumours which develop at the level of the submucous bronchial glands of the tracheobronchial tree. The majority of these tumours develop in a benign fashion but some of them are malign. Amongst these many are probably confused with adenosquamous bronchial cancers. We have reviewed eleven patients suffering from TME who were observed over a period of twelve years. Two of these tumours were at the level of the trachea: nine others were at the level of the bronchial cartilaginous trachea. Seven of these tumours had the macroscopic and histological criteria of low grade malignancy and four corresponded to those tumours said to show high grade malignancy. The only death concerned a patient with a tracheal tumor of high grade malignancy but the death occurred immediately after laser therapy to relieve obstruction in a patient with acute asphyxia. None of the other patients died of tumour progression and the longest follow up (eleven years of survival) involved a patient with a bronchial form and a high grade malignancy with glandular invasion. Even mucoepidermoid tumours of high grade malignancy have a good prognosis and it is a cardinal point to clearly distinguish these forms from adenosquamous cancers. Nevertheless it has been suggested that adenosquamous and mucoepidermoid carcinomas could have a common origin and be the extremes of the same overall disorder just as the image we have of neuroendocrine tumours whose spectrum extends from carcinoid tumours to small cell cancers.

Abstract
A very rare case of a childhood bronchial mucoepidermoid tumor is presented. A 4-year-old girl was hospitalized with prolonged pneumonia. Computed tomography of the chest showed a tumor with calcifications in the right upper lobe. Subsequently, the patient underwent right upper lobectomy. Histologically, the tumor was a low-grade mucoepidermoid tumor originating from the bronchus. Three years postoperatively there has been no evidence of disease. A review of the literature indicates that 30 cases of bronchial mucoepidermoid tumors in children have been reported. Symptoms result from associated bronchial obstruction. Children with recurrent or prolonged pneumonia should undergo aggressive diagnostic investigation by chest tomography or bronchoscopy. Appropriate therapy for childhood bronchial mucoepidermoid tumor is total resection of the lesion while sacrificing as little of the normal lung tissue as possible.

Abstract
Cervical lymph-node treatment in parotid gland epithelial malignancies is still debated. According to Literature, three different strategies (surgery, radiotherapy, "wait and see") have all been proposed theoretically, particularly when dealing with N0 cases. The present study was designed to evaluate the results of different lymphonode treatment strategies in 57 parotid gland carcinomas followed at the ENT Clinic of the University of Ferrara. The most frequent hystological patterns appeared to be the adenoidcystic carcinoma (33.3%) and the mucoepidermoid tumor (21.1%). Total parotidectomy was the treatment of choice in all cases. Ipsilateral neck dissection was performed in 14 cases (24.5%), 5 cases being N0. In 27 patients (47.4%) postsurgical radiotherapy was applied: in 7 cases on T and in 20 on both T and N.T recurrences were 7, while those of N and of both T and N were respectively 2 and 2. No occult metastases were found in N0 dissected patients. The results obtained led the Authors to the following conclusions: -neck dissection is fundamental in treatment of clinical adenopathies in any parotid gland malignancy: -postsurgical radiotherapy on the neck is the treatment of choice in all N0 carcinomas except in cases of acinic cell and mucoepidermoid carcinomas, where a "wait and see" policy seems to be more suitable.

Abstract
The glandular odontogenic cyst (GOC) is a rare odontogenic cyst which is still controversial in regard to classification, terminology, and origin. The first Japanese case of GOC is reported. Immunohistochemical examination for expression of cytokeratins and epithelial membrane antigen by monoclonal antibodies suggested that the lining epithelium was of odontogenic origin with metaplastic mucus-laden cells. We have reviewed the literature and compared the clinicopathological findings of the reported case of GOC with those of botryoid odontogenic cysts (BOC). The anatomical location, age range, and sex of GOC cases were very similar to those of BOC. GOC appears to be a multiocular and mucoepidermoid variant of non-keratinizing odontogenic cysts, which also includes BOC. GOC should be separated from the other types of odontogenic cyst and central mucoepidermoid tumours of salivary gland origin.
