Epithelial-myoepithelial carcinoma of the salivary glands: a clinico-pathologic, immunohistochemical and DNA flow cytometric study of three cases.

Epithelial-myoepithelial carcinoma is a rare neoplasia of the salivary glands. Histologic, immunohistochemical and flow cytometry analysis were used to study three new cases involving the major salivary glands of two women and one man. The mean age was 66.7 years. Immunohistochemistry confirmed the epithelial-myoepithelial dualism of the tumors: the predominant growth pattern showed ducts made up of an external myoepithelial layer and an internal epithelial layer. Proliferative activity, assessed by means of the PCNA and Ki-67 immunostaining and the study of the S-phase with flow cytometric analysis, proved to be higher in a recurrent case. All three cases were diploid. The use of immunohistochemical and flow cytometric techniques for the assessment of proliferative activity would seem to be an efficient method for the selection of a subgroup of epithelial-myoepithelial carcinomas with unfavorable prognosis.

Malignant myoepithelioma of the minor salivary glands arising in a pleomorphic adenoma.

This paper reports a case of carcinoma expleomorphic adenoma of the minor salivary glands, where the carcinomatous component was a malignant myoepithelioma (myoepithelial carcinoma). Immunohistochemical investigation showed that the carcinoma cells were positive for cytokeratin, S-100 protein and vimentin, and focally positive for actin and desmin. A moderate level of positivity was found fo laminin and collagen IV around the neoplastic islands. These data are the confirmation that the carcinoma cells were myoepithelial. The number of mitoses, the istotype, the minimal extent of extracapsular infiltration and the absence of vascular invasion made it possible to include this particular case among those with a better prognosis.

Node status in lower lip squamous cell carcinoma in relation to tumor size, histological variables and DNA ploidy.

We studied a consecutive series of 54 cases of lower lip squamous cell carcinoma (LLSCC) in order to identify any variables which might predict the development of lymph node metastases. The cases were divided into 38 tumors without metastases (group I) and 16 tumors with lymph node metastases (group II). The following variables were investigated: tumor size, histologic grading, tumor maximal thickness, perineural infiltration and DNA ploidy, in a group of patients undergoing surgical treatment for LLSCC, and to show which of these might be predictive of the development of lymph node metastases.
