Pleomorphic adenoma is mixed and usually benign tumor originating salivary glands. The most common salivary gland tumor is pleomorphic adenoma. The most common localization of pleomorphic adenoma is parotid gland. Although it is found in major salivary gland, pleomorphic adenoma may be found paranasal sinuses and nasal cavity rarely. A 74-year-old female presented with a 3-month history of ri...

introduction: pleomorphic adenoma is a rare benign salivary gland neoplasm in children, which can be treated by simple excision. this tumor is rarely included in the differential diagnosis of solid submandibular masses in children. in the neonates, congenital pleomorphic adenoma usually presents in the nasopharynx. surgical excision is the treatment of choice and recurrence is not expected. we ...

Background: Carcinoma ex pleomorphic adenoma is an exceedingly rare neoplasm of the submandibular gland with an overall poor prognosis. Metastatic deposits of carcinoma ex pleomorphic adenoma are either composed exclusively of malignant elements or contain mixed benign and malignant components. Case Presentation: We describe the case of a 63-year-old male with a carcinoma ex pleomorphic adenoma...

discussion benign metastasizing pleomorphic adenoma is a rare and controversial but distinct clinical entity. although the definition of the term benign precludes metastatic disease, these tumors do not demonstrate any malignant features yet metastasized to distinct sites. it remains to be determined whether this benign metastasizing pleomorphic adenoma is really low grade salivary malignancy. ...

introduction: salivary gland tumors (sgts) are important parts of human neoplasms. the most common sgt is pleomorphic adenoma and the most common malignant sgts are mucoepidermoid carcinoma and adenoid cystic carcinoma (acc). metastasis-associated genes 1 (mta1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...

Immunohistological expressions of the cytokeratin (CK) subclass, vimentin, glial fibral antigen protein (GFAP), alpha-smooth muscle actin, and S-100 protein were investigated in pleomorphic adenoma of the parotid gland. In addition, the correlation between immunohistological findings in the normal parotid gland and those in pleomorphic adenoma was examined. Vimentin, S-100 protein, and GFAP, wh...

INTRODUCTION Pleomorphic adenoma accounts for 65 percent of all salivary gland tumors. It has been identified in several anatomical regions, but pleomorphic adenoma arising in the ear canal, first described in 1951, is extremely rare. CASE PRESENTATION A 40-year-old Japanese man's left ear canal was obstructed by a pleomorphic adenoma that caused mild conductive hearing loss. The tumor was re...

OBJECTIVE: To report a case of pleomorphic adenoma that was surgically removed and to describe the surgical technique available remove this lesion. CASE REPORT: A male patient, caucasian, 46 years old, with 4-year history adenoma. He mentioned he went other services for treatment, but without success. came at our service treatment tumoral excision. Local anesthesia performed mepivacaine vasocon...

Introduction: Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...

a rare case of squamous cell carcinoma ex pleomorphic adenoma in maxillary sinus is presented. the patient is a 50-year-old woman presenting with a slow-progressive swelling in left side of her face that she has noticed 2 years earlier. the lesion was not painful and caused asymmetry and mild exophthalmos. microscopic examination revealed that the tumor was composed of two components partly of ...
