Oncocytic papillary cystadenoma is a rare, benign tumor highly uncommon in the larynx. Although controversy exists regarding its true nature it is considered a phenomenon of metaplasia. We present the case of a 57-year-old patient with synchronous, bilateral oncocytic papillary cystadenoma of the ventricles and we discuss the current literature.

Oncocytic carcinoma of the salivary glands is an extremely rare malignant neoplasm. The parotid is the most frequently involved salivary gland, but tumours in the submandibular gland and minor salivary glands have also been described. It appears that oncocytic carcinoma of an ectopic salivary gland has not been reported so far.

In the current study, polymorphisms located in angiogenesis- and apoptosis-related genes (, , and ) were evaluated regarding their clinical significance in HNC patients. In total, 333 HNC patients were enrolled in this study and 34 variants located on the aforementioned genes were genotyped via Sanger sequencing.

Materials And Methods: Tumors from 289 patients with squamous cell laryngeal cancer were assessed for protein (immunohistochemistry) and mRNA (qRT-PCR) expression of Notch pathway components (Notch1 to 4 receptors and Jagged1 ligand) on tissue microarrays.
Results: In univariate analysis, enhanced nuclear Jagged1 expression conferred a longer disease-free survival (DFS) (p=0.
