Myoepithelioma of minor salivary gland - An immunohistochemical analysis of four cases

Myoepithelioma of minor salivary gland--an immunohistochemical analysis of four cases.

INTRODUCTION AND METHODS We performed an immunohistochemical study in four cases of myopitheliomas with objective to realize a profile in respect of differentiation grade by the monoclonal antibodies CK14, vimentin and alph-SMA, besides to investigate the cell proliferation by anti-PCNA, besides, we compare the immunoreactive with glandular normal tissue. RESULTS In the glandular normal tissu...

Plasmacytoid myoepithelioma of minor salivary glands: report of case with emphasis in the immunohistochemical findings

Myoepithelioma is a rare benign tumor of the salivary glands and is usually seen in the parotid gland and the minor salivary glands. It was once considered to be a type of pleomorphic adenoma (PA), but myoepitheliomas are today believed to be relatively aggressive tumors. Myoepitheliomas are most common in young adults between the ages of 30 and 50 and there are very few cases reported in indiv...

Salivary gland Basal cell adenomas--immunohistochemical evaluation of four cases and review of the literature.

OBJECTIVE Evaluate the antigen profile of cellular population from basal cell adenomas. MATERIAL AND METHODS Histopathological and immunohistochemical evaluation of four-salivary gland basal cell adenomas; the pathological samples were provided by the Oral Maxilla Facial Surgery Department of the Clinical County Hospital from Craiova.

Myoepithelioma of a minor salivary gland of the cheek: case report.

Myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary gland of the oral cavity. The histological appearance includes solid, myxoid and reticular growth patterns. Vimentin and S-100 protein are very sensitive but non-specific immunohistochemical markers of neoplastic myoepithelium. Conservative surgery is...
