INTRODUCTION Pleomorphic adenomas are tumors mostly originating from salivary glands. These lesions in the larynx are very rare. CASE REPORT We report a rare case of pleomorphic adenoma that originated from the mucosal lining, just above the glottic area at the level of the laryngeal ventricle in a 55-year-old female patient. The tumor could not be palpated easily but was observed in the CT s...

OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of fine needle aspiration (FNA) cytology of benign salivary gland tumors with myoepithelial cell participation, namely, pleomorphic adenoma, basal cell adenoma and myoepithelioma, at a single institution over a period of 10 years. STUDY DESIGN This study was based on 575 cytologic and matching histological samples (534 pl...

background: the most common neoplasm of the salivary glands is pleomorphic adenoma and the most common complications of its surgical removal are facial nerve dysfunction (temporary or permanent) and auriculotemporal syndrome (frey’s syndrome). one of the surgical techniques in pleomorphic adenoma is partial parotidectomy. the whole excised tumor is surrounded by a safety margin of parotid tissu...

introduction the application of immunohistochemical method has resulted in marked improvement of the microscopic diagnosis of neoplasms combined with h&e; staining. although unique cellular antigens have not been found in salivary gland neoplasms, multiple less specific immunomarkers have been used and may be helpful in elucidating the role of myoepithelial differentiation in those neoplasms. t...

A 65 year old man presented with a right upper cervical mass. A diagnosis of pleomorphic adenoma was reported on fine needle aspiration cytology (FNAC). CT scan however reported an intramuscular sternocleidomastoid swelling. The tumor was excised and a diagnosis of nodular fasciitis was made. It is important to be aware of this diagnosis and that FNAC reports may mimic that of a pleomorphic ade...

Pleomorphic adenoma, also called benign mixed tumor, is the most common tumor of the salivary glands. About 90% of these tumors occur in the parotid gland and 10% in the minor salivary glands. The most common sites of pleomorphic adenoma of the minor salivary glands are the palates followed by lips and cheeks. Other rare sites include the throat, floor of the mouth, tongue, tonsil, pharynx, ret...

BACKGROUND Pleomorphic adenomas, also known as benign mixed tumors, are the most common tumors of glandular origin in the head and neck and although they are generally benign they can undergo malignant transformation. Primary pleomorphic adenomas of the lung are extremely rare tumors with less than 40 cases reported in the literature by now. This is the first case in the literature describing o...

A rare case of pleomorphic adenoma arising from the nasal septum is presented. Computed tomography (CT) and magnetic resonance imaging (MRI) of a 65- year-old woman who presented with right sided nasal obstruction, nasal discharge and epistaxis revealed a well-defined lobular mass occupying the right nasal cavity. Histopathologic examination revealed a pleomorphic adenoma. CT and MRI findings o...

Pleomorphic adenoma is one of the most frequent tumors that involve the parotid gland. The tumor constantly increases in dimension if not cured in due time and may become malignant. A case of a patient suffering from a carcinoma ex-pleomorphic adenoma that had a 20-year-evolution and reached impressive dimensions is presented. The tumor holds the second place worldwide among the largest carcino...
