T he index study to describe rare case of pleomorphic adenoma of soft palate diagnosed by FNAC (fine needle aspiration cytology). The occurrence of pleomorphic adenoma de novo in the soft palate is a rare picture, and therefore, it should be considered in the differential diagnosis of all palatal swellings. Pleomorphic adenoma (PA) is benign tumor of salivary gland. The diagnosis of Intraoral Pleomorphic Adenoma can be confirmed through a tissue biopsy. Pleomorphic adenoma with these types of metaplastic changes can rather easily be confused with mucoepidermoid carcinoma [22, 43, 47, 64].
