Introduction: Granular cell tumors (GCTs) are of neuroectodermal origin and account for 0.5% of soft tissue tumors. They are most prevalent in African-Americans in the fourth to sixth decades, with a predilection for the head and neck regions. GCTs usually resemble more common lesions and hence are difficult to diagnose preoperatively. The tumor is readily identified on needle biopsy. Although usually benign with a malignancy rate of only 2-3%, the malignant form has a reported 3-yr mortality of 60%...

Head and neck squamous cell carcinomas (HNSCC) are a diverse group of tumor types, including neoplasia of the paranasal sinuses, oral cavity, trachea, pharynx and larynx. Laryngeal cancer is the most common type of HNSCC. The proline-rich 4 (PRR4) protein is synthesized in the acinar cells of human lacrimal glands. Previous studies have demonstrated that PRR4 may function as an antimicrobial protein protecting the ocular surface and the oral cavity. In order to determine differentially expressed genes (DEGs) in laryngeal tumors, a GeneFishing Assay was performed; 27 DEGs were identified...

BACKGROUND: Patients suffering from squamous cell carcinoma of the larynx (LSCC) with lymphatic metastasis have a relatively poor prognosis and often require radical therapeutic management. The mechanisms which drive metastasis to the lymph nodes are largely unknown but may be promoted by a pro-angiogenic tumor microenvironment. In this study, we examined whether the number of microvessels and the expression level of vascular endothelial growth factor (VEGF) in the primary tumor are correlated with the degree of lymph node metastasis (N-stage), tumor staging (T) and survival time in LSCC patients...

IMPORTANCE: Transoral robotic surgery has revolutionized the practice of head and neck surgery over the past decade, with indications now expanding to include laryngeal pathology. Although laryngeal chondrosarcoma is a rare entity, trends in otolaryngology literature suggest that it can frequently be managed with conservative approaches. We hope to inspire other head and neck surgeons to consider transoral robotic surgery for the treatment of such tumors so that outcomes data can be collected and studied...

PURPOSE: Programmed cell death 4 (PDCD4) is decreased in many malignant tumors. Epithelial mesenchymal Transition (EMT) endows tumor cells invasive and metastatic properties. Few studies have elucidated the role of PDCD4 in the regulation of EMT during laryngeal carcinoma. METHODS: Using laryngeal carcinoma tissues, the relationship between PDCD4 and EMT-associated proteins E-cadherin and N-cadherin was examined. Gene manipulation was utilized to define the regulatory capacity of PDCD4...

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder that has nodal and extranodal manifestations. Currently no guidelines are available for the management of this disease. We report a case of laryngeal RDD that did not present with classical symptoms such as fever or lymphadenopathy and could be easily misdiagnosed as malignant tumor. The patient received minimally invasive surgeries combined with steroid therapy to preserve the laryngeal function as much as possible, and a favorable clinical outcome was obtained...

BACKGROUND: LZTS2 (leucine zipper tumor suppressor 2), a candidate tumor suppressor gene, suppresses cell growth and plays a vital role in the carcinogenesis and development of tumors. No studies to date have described methylation of the LZTS2 promoter in human cancers, including LSCC (laryngeal squamous cell carcinoma). Therefore, the aim of this study was to explore the relationship between LZTS2 promoter methylation and risk of LSCC. METHODS: In our study, LZTS2 promoter methylation levels in LSCC tumor and adjacent normal tissues from 96 patients were measured using quantitative methylation-specific polymerase chain reaction (qMSP) assays...

BACKGROUND: As hybrid RNAs, transcription-induced chimeras (TICs) may have tumor-promoting properties, and some specific chimeras have become important diagnostic markers and therapeutic targets for cancer. METHODS: We examined 23 paired laryngeal cancer (LC) tissues and adjacent normal mucous membrane tissue samples (ANMMTs). Three of these pairs were used for comparative transcriptomic analysis using high-throughput sequencing. Furthermore, we used real-time polymerase chain reaction (RT-PCR) for further validation in 20 samples...

In solid tumors the biology and clinical course are strongly influenced by the interaction of tumor cells and infiltrating stromal host cells. The aim of this study was to assess the relative importance of stromal vs. tumoral inflammation for metastasis and survival in patients with laryngeal squamous cell carcinoma (LSCC). In 110 patients with tissues from histologically proven LSCC the expression of CD45, CD11b, CD3, MMP-9 and COX-2 was semiquantitatively analyzed in stromal regions and tumor nests. CD45, CD11b, CD3 and MMP-9 positive cells were more abundant in stroma whereas COX-2 was predominantly expressed in epithelial tumor nests...
