The mucoepidermoid carcinoma is the commonest of all malignant tumors of salivary glands, accounting for the 30 % of them. Approximately the half of cases (53 %) occurs in the major salivary glands. The 45 % has predominance in parotid gland, the 7 % in the submandibular one, and the 1 % in the sublingual gland one. This type of tumor is more frequent in female sex (3-2) and at fifth decade of life. Multiple variants with different ranks have been described including the oncocyte, sclerosant, unicystic, sebaceous, of clear cells, high degree spherical cells, fusocellular and psammomatous. The mucoepidermoid carcinoma, oncocyte variant, is an unusual subtype that may to shows significant oncocyte changes. Authors report a case of histological high degree mucoepidermoid carcinoma. The rate of Ki 67 was of 5 %, the negative tumor for C-erb2 and had immunoreaction to E-caderine and Syndecan-1.

Keywords : Salivary glands; oncocyte mucoepidermoid carcinoma.
