Primary tracheal tumors are very rare. Pleomorphic adenoma is rarely found in the trachea, despite being the most common histological form of salivary gland neoplasm. We present a case of pleomorphic adenoma of the trachea. Bronchoscopic excision using cold instruments resulted in apparently normal tracheal mucosa.

Carcinoma ex pleomorphic adenoma is an exceedingly rare neoplasm of the minor salivary gland. Prognostic parameters are recurrence, capsular invasion, and metastasis. We present a case of carcinoma ex pleomorphic adenoma with pulmonary metastasis to emphasize that patients treated for this condition should be investigated for distant metastasis.

The pleomorphic adenoma is the most common salivary gland tumor. A remarkable morphological diversity can exist from one tumor to the next. We present here a case of pleomorphic adenoma of minor salivary glands of the soft palate which had predominantly myoepithelial cells with minimal stroma, ductal cells, or tubular elements.

OBJECTIVES Pleomorphic adenomas are the most frequent type of epithelial salivary gland neoplasms, and their malignant counterpart, the carcinoma in pleomorphic adenomas, is much less common. Beta-catenin is a cell adhesion molecule associated with the invasion and metastasis of carcinomas of the head and neck, esophagus. The objective of this study was to detect the expression of beta-catenin ...

Among neoplasia of head and neck, Salivary gland tumours are rare it comprises about less than 3%.Pleomorphic adenoma is the most common benign tumour all salivary tumours, which so called mixed due its wide cyto-morphological architectural diversity. In this case report we presenting a pleomorphic buccal mucosa in 56 year old male patient who reported to our department with complaint pain swel...

abstract salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. most benign tumors occur in the parotid gland. pleomorphic adenoma is the most common type. basal cell adenoma is a subtype of the monomorphic adenoma with rare occurrence. proper diagnosis and clinical evaluation by the use of radiography can lead the physician to t...

OBJECTIVE This study aimed to characterize alteration in the immunohistochemical expression of p16 in normal tissue of the salivary gland surrounding pleomorphic adenoma, and the tumor cells of pleomorphic adenomas. MATERIAL AND METHOD A selected series of 120 cases of pleomorphic adenomas were examined. RESULTS The results showed that p16 expression in non tumor duct cells was strong posit...

background and aims. salivary gland tumors are rare and specific lesions. there are differences in the incidence and frequency of salivary tumors in both minor and major salivary glands in different countries. this study was carried out to determine the prevalence of major and minor salivary gland tumors in ahvaz in the south of iran. materials and methods. all the cases, recorded in imam khome...

AIM OF THE STUDY This study aims to characterise alterations in the immunohistochemical expression of p27 in normal tissue of the salivary gland surrounding pleomorphic adenoma and in the tumour cells of pleomorphic adenoma. MATERIAL AND METHODS A retrospective study of data including 120 cases of pleomorphic adenomas (66 female, 54 male) retrieved from the files of the Oral Pathology Departm...
