Pleomorphic adenoma is a common neoplasm of salivary glands, but its occurrence in the trachea is very rare [1] . Tracheal tumors, including tracheal pleomorphic adenoma, often cause obstructive symptoms such as dyspnea and wheezing mimicking asthma, leading to delay in diagnosis [2] . Because of the rarity, consensus with regard to clinical behavior, management or prognosis is A 55-year-old ma...

Myoepithelial carcinoma, arising in a recurrent or in a pre-existing pleomorphic adenoma of the parotid gland is an extremely rare cancer. We herein report the case of myoepithelial carcinoma occurring in a recurrent pleomorphic adenoma, which showed a high metastatic potential. A 53-year-old male, who had undergone a superficial parotidectomy of the pleomorphic adenoma 2 years previously, pres...

Pleomorphic adenomas are the most common benign tumor of the major salivary glands. In addition, they may also occur in the minor salivary glands of the hard and soft palate. Nasal masses are often due to antrochoanal or ethmoidal polyps or angiofibromas or haemangiomas or papillomas. Intranasal pleomorphic adenomas are very unusual and may be misdiagnosed because they have greater myoepithelia...

Pleomorphic adenoma is the most common salivary gland neoplasm, and it can be locally invasive, despite its slow growth. This study aimed to establish a novel cell line (AP-1) derived from a human pleomorphic adenoma sample to better understand local invasiveness of this tumor. AP-1 cell line was characterized by cell growth analysis, expression of epithelial and myoepithelial markers by immuno...

PURPOSE To describe and analyze the features of a cases series of patients with primary epithelial neoplasms of the lacrimal gland, its surgical treatment, and histopathological findings. METHODS Retrospective evaluation of files from patients with primary epithelial neoplasms of the lacrimal gland in the period from 1997 to 2007. All patients with primary epithelial tumors of the lacrimal gl...

neoplasms that arise in the salivary glands are relatively rare, yet they represent a wide variety of both benign and malignant histologic subtypes. approximately 70% of the salivary gland tumors affect parotid gland with the submandibular gland being affected in 5-10% of the cases, sublingual gland in 1% and minor glands in 5-15% of the cases. submandibular gland tumors are relatively rare and...

Objective The aim of our study was to present our findings in a series of patients who were treated for recurrent parotid pleomorphic adenoma with their clinical, surgical, and follow-up information and to discuss them in light of the recent literature. Methods Eleven patients who had revision surgery for recurrent pleomorphic adenoma at our institution were retrospectively analyzed for the c...
