Intraoral pleomorphic adenoma is a rare entity, with the most common site of appearance being the palate. As a benign lesion, it rarely involves underlying structures. The aim is to present a case of a palatal pleomorphic adenoma (cellular) with bone involvement, with reference to clinical and histological features of the tumour, emphasis on diagnostic and therapeutic management and comparison with the findings of similar studies in the literature. Pleomorphic adenomas of the palatal minor salivary glands remain a rather rare clinical condition, and it is unusual to infiltrate the adjacent palatal bone. A thorough clinical imaging and histological/cytological examination should always be performed to define the benign or malignant nature of the lesion, preoperatively.
