Myoepithelioma of the larynx is a very rare tumor with nonspecific local symptoms. We present the second known case, focusing on the peculiarities of the differential diagnosis for this type of tumor that are crucial for the right histologic diagnosis and furthermore for the therapeutic outcome.We report a 37-year-old male presenting with hoarseness and dyspnea. The indirect laryngoscopy revealed a gross glottic tumor from the right vocal cord who occupied the greater part of the glottis. No apparent cartilage invasion was shown in the CT. He came to us with a previous direct laryngoscopy derived biopsy describing a chondroma. A modified vertical partial laryngectomy, under temporary tracheostomy, with muscle reconstruction for the deficit of the right vocal cord was applied for the removal of the tumor. The final histopathologic diagnosis was myoepithelioma (spindle cell type) of the larynx. A long term follow-up in our case showed no recurrence and a good functional result.The larynx is a very rare localization for this type of tumour. The benign character of the disease in conjunction with its slow progression could delay its detection and diagnosis, leading to a more destructive surgery. A detailed pathology examination is prerequisite for avoidance of misleading diagnosis.

We describe a case of a pleomorphic adenoma (PA) arising from the para-tracheal accessory salivary gland in a 44-year-old male harboring a novel WWTR1::NCOA2 gene fusion. To our knowledge, this novel gene fusion has not been described previously in salivary gland tumors. The patient presented with hoarseness of voice.

Myoepitheliomas (MEs) are extremely rare benign neoplasms composed of ectodermally derived contractile smooth muscle cells (myoepithelial cells). Various tissues such as the salivary glands, breast, larynx, and sweat glands show the presence of these myoepithelial cells. They occur, principally, in the parotid gland and infrequently in minor salivary glands.

Objective: Clinical studies demonstrating the prognostic factors in submandibular gland carcinoma are limited because the tumor is relatively rare. The aim of this study was to identify clinical outcomes and prognostic factors in submandibular gland carcinoma.
Methods: The study included 65 patients with submandibular gland carcinoma who underwent initial surgical treatment at the Kyoto University and its affiliated hospitals.

Objective: To define the incidence and pattern of spread of lymph node metastasis from parotid cancers and to clarify the risk factors and appropriate extent of neck dissection (ND) for individual patient with parotid cancer.
Methods: A total of 72 patients with parotid gland cancer treated by surgery between 1994 and 2013 were analyzed retrospectively by reference to medical records. In line with our protocol, patients with clinically positive lymph nodes and/or cT3/T4 disease were generally selected to undergo ND.
