Periorbital nerve enlargement commonly indicates perineural invasion of malignancy or inflammatory conditions. This study reviews the role of supraorbital and infraorbital nerve biopsies in patients presenting with radiographic enlargement and to elucidate the surgical technique involved. A retrospective chart review (1997-2014) was performed at a single tertiary center. Patients with radiographic confirmation of enlarged supraorbital/infraorbital nerves that underwent biopsy were included. Charts were reviewed for: patient demographics and history, clinical symptoms and findings, radiographic findings, surgical method, and treatment...

Proteomics analysis of chronic cigarette smoke exposure is a rapidly emerging postgenomics research field. While smoking is a major cause of lung cancer, functional studies using proteomics approaches could enrich our mechanistic understanding of the elusive lung cancer global molecular signaling and cigarette smoke relationship. We report in this study on a stable isotope labeling by amino acids in cell culture-based quantitative phosphoproteomic analysis of a human lung mucoepidermoid carcinoma cell line, H292 cells, chronically exposed to cigarette smoke...

OBJECTIVES: Mucoepidermoid carcinoma (MEC) is an uncommon malignancy that most commonly occurs in the parotid gland followed by the minor salivary glands of the upper aerodigestive tract, most notably in the oral cavity (OC) and oropharynx (OP). Because of its rarity, few studies have been performed that are specific to MEC within the OC and OP. The objective of this study is to describe the tumor characteristics and prognostic features for MEC of the OC and OP. MATERIALS AND METHODS: The National Cancer Database (NCDB) was used for this study...

Mucoepidermoid carcinoma (MEC) shows a wide morphologic spectrum, including epithelium with oncocytic or squamous metaplastic changes overlying a prominent cystic architecture, as well as tumor-associated lymphoid tissue. We illustrate a case of MEC of the parotid in a 17-year-old female, in which all these features occurred extensively, such that they accounted for almost the entire neoplasm, and closely mimicked Warthin tumor histologically. This highlights the need for diagnostic awareness of this particular morphologic variant of MEC, as patients could potentially be inappropriately discharged from follow-up if diagnosed with a benign neoplasm...

A 65-year-old woman was found to have a mass shadow on chest computed tomography. The patient had been diagnosed as having myelodysplastic syndrome 3 years before admission. She was transferred to our hospital for further examination of the mass in the lower lobe of left lung. The mass was positron emission tomography-positive (SUVmax of 8.6)suggesting a malignant neoplasm. Serum concentrations of carcinoembryonic antigen was elevated to 8.7 ng/ml. Preoperative laboratory studies showed anemia (hemoglobin 6...

OBJECTIVES: Chemokine receptors have been shown to overexpress in several cancer types. Binding of chemokines to their cognate chemokine receptors on tumor cells can promote tumor growth, angiogenesis and metastasis. The purposes of this study was to examine the expression of chemokine receptors, CXCR4 and CXCR7, in salivary gland neoplasms and its association with pathologic characteristics. DESIGN: Sixty-two cases of salivary gland neoplasms, including 25 mucoepidermoid carcinomas (MEC), 18 adenoid cystic carcinomas (ACC), 14 pleomorphic adenomas (PA) and 5 polymorphous low-grade adenocarcinoma (PLGA) were investigated for CXCR4 and CXCR7 expression immunohistochemically...

There is a steady rise in incidence of malignant salivary gland tumors in the United States, with mucoepidermoid carcinoma (MEC) the most frequent. Although 40% of MECs are found in the parotid gland, these lesions possess the capacity to develop anywhere along the aerodigestive tract. Here, we present a case of recurrent tongue MEC in a young adult female patient with history of lung malignancy and multiple brain metastases. Without a universally accepted management protocol for recurrent MECs, the current clinical practice uses tumor grade, location, and clinical progression to determine both prognosis and goals of care...

Warthin-like mucoepidermoid carcinoma is a recently proposed variant of musoepidermoid carcinoma. Histologically, it is characterized by its close resemblance to Warthin tumor, including dense lymphocytic infiltration, flattened intermediate epithelium resembling squamous metaplasia, and cystic change. Given its histologic similarity to Warthin tumor, confirmatory testing for MAML2 rearrangement is often required for this diagnosis. Here we present the first cytologic reports of two 53-year-old female patients with parotid masses...

Salivary gland epithelial neoplasms are rare in children and adolescents with only a handful of large series have been published. A retrospective study was conducted for 57 cases in patients 20years or younger. The tumors were located in the parotid (n=36), submandibular gland (n=7), and minor salivary glands (n=14). 19 (33%) tumors were pleomorphic adenoma, while the remaining (67%) were malignant. The histologic types of carcinomas were mucoepidermoid carcinoma (MEC, n=19, 33%), acinic cell carcinoma (n=7, 12%), adenoid cystic carcinoma (n=6, 11%), secretory carcinoma (mammary analogue) (SC, n=4, 7%), and myoepithelial carcinoma (n=2, 4%)...

Bronchial tumors are rare in children. Most of them are malignant, being the carcinoid tumor the most common. Less frequently the mucoepidermoid carcinoma is found in the tracheobronchial tree. Mucoepidermoid carcinoma accounts for 0.1 to 0.2% of all malignant bronchopulmonary tumors. It manifests with symptoms of airway obstruction and/or recurrent pneumonias. Early diagnosis and appropriate treatment are of great importance in the prognosis. Bronchoscopy with biopsy of the endobronchial mass is the method of choice to confirm the diagnosis...

An 11 years old boy was referred to our hospital. He complained for the last three months for intermittent cough and shortness of breath after exercise which worsened recently. Airways computed tomography (CT) showed an abnormal endobronchial tumor, obstructing the right main bronchus and also atelectasis in the upper lobe of the right lung. Bronchoscopy showed a wet on its surface mass obstructing the right main bronchus. Biopsy showed a mucoepidermoid carcinoma (MEC). The fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scan showed in the same area a mass with slightly increased (18)F-FDG uptake (maximum standardized uptake value, SUVmax: 3...

Perineural spread (PNS) in head and neck malignancies has been associated with extremely poor prognosis. Through this interesting case, we demonstrate the PNS of a mucoepidermoid carcinoma of parotid gland with simultaneous involvement of V, VI, and VII cranial nerves identified on positron emission tomography/computed tomography.

Mucoepidermoid carcinoma of the lung is a rare malignancy of salivary gland-type origin. We report a case of a 21-year-old man with a right mainstem bronchus mass composed predominantly of clear cells. This case represents a rare primary pulmonary low-grade mucoepidermoid carcinoma positive for MAML2 rearrangement by fluorescence in situ hybridization with a prominent clear cell component.

Mucoepidermoid Carcinoma (MEC) is the most common malignant neoplasm of salivary gland origin. However, its morphologic heterogeneity poses difficulty in interpretation. In the present series we discuss the morphologic features of MEC, limitations and pitfalls in its diagnosis on Fine Needle Aspiration Cytology (FNAC). Fourteen cases of suspected MEC were evaluated cytologically followed by histopathological examination for confirmation. A definite cytological diagnosis was rendered in nine cases; three of the remaining five were underdiagnosed as abscess, pleomorphic adenoma and mucus cyst...

Acinic cell carcinoma is a rare tumour comprising 1%-3% of all salivary gland neoplasms. Acinic Cell Carcinoma Papillary Cystic Variant (ACC-PCV) is a distinct subtype and shows variegated appearance on cytology. It is important to differentiate it from other malignant lesions because of its poor prognosis. We describe a case of 20-year-old female with swelling on left cheek for the last four months. Fine needle aspiration was done and diagnosed as intermediate grade mucoepidermoid carcinoma on cytology. Histological study of the resected tumour showed features of ACC-PCV...

In mucoepidermoid carcinoma (MEC), the most common salivary gland carcinoma, there is a lack of novel prognostic markers, but post-operative early recurrence strongly affects the clinical course and a poor outcome. It is critical to predict which MEC patients are prone to develop recurrence/metastases. Mucins play pivotal roles in influencing cancer biology, thus affecting cell differentiation, adhesion, carcinoma invasion, aggressiveness and/or metastatic potential. Our aim is to elucidate the significance of expression profiles for mucins, particularly MUC4 and MUC6, and their correlations with various clinicopathological features and recurrence in salivary gland MECs...
