ABSTRACT Mucoepidermoid carcinoma ex pleomorphic adenoma (MCxPA) is a rare salivary gland tumor predominantly found in major salivary glands. A case of MCxPA involving the soft tissue and bone of the retromolar region of a 26-year-old man is presented. The histopathological features revealed a neoplasm with predominance of pleomorphic adenoma (PA) elements, and presence of mucoepidermoid carcinoma malignant epithelial cells in several areas. Histochemical and immunohistochemical studies were positive for periodic acid Schiff, alcian blue, cytokeratins 7, 13, 14, and 19, Bcl-2, c-erbB-2, FGF-2 and maspin in the malignant areas. The patient underwent a partial resection of the left side of the mandible with neck dissection and MCxPA diagnosis was confirmed.

Abstract Assessment of proliferation is a means of predicting local recurrence and metastatic potential of malignancies. A mitotic count is not an ideal marker for proliferation in certain situations, such as salivary gland neoplasms. Ki-67 expression as a proliferation marker has been investigated in many human tumors. In the present study, Mitotic index (MI) and Ki-67 index were studied in pleomorphic adenoma, basal cell adenoma, mucoepidermoid carcinoma, adenoid cystic carcinoma epithelial myoepithelial carcinoma, carcinoma ex Pleomorphic adenoma and adenocarcinoma of salivary glands. The results were compared. The MI was similar in benign neoplasms, mucoepidermoid carcinoma and epithelial myoepithelial carcinoma, whereas it was high in carcinoma ex pleomorphic adenoma, adenocarcinoma and adenoid cystic carcinoma. The Ki-67 index was different in basal cell adenoma and pleomorphic adenoma. It was helpful in differentiating high grade and low grade mucoepidermoid carcinoma. It highlighted the malignant behavior of epithelial myoepithelial carcinoma. It was concluded that Ki-67 in benign neoplasms is 5% or less and in malignant ones more than 23% with a few exceptions. In mucoepidermoid carcinoma and epithelial myoepithelial carcinoma, Ki-67 index was found to be a better indicator for aggressiveness. These findings will be presented in this paper, with review of literature. How to cite this article Kaza S, Rao TJM, Mikkilineni A, Ratnam GV, Rao DR. Ki-67 Index in Salivary Gland Neoplasms.
