Pleomorphic adenoma may develop from minor salivary glands of the sinonasal epithelium, prevalently in the nasal cavity. Involvement of the anterior skull base has been observed, especially in recurrent tumours [48]. The tumour has a similar macroscopic appearance to those of major glands; association with carcinoma should always be excluded by careful analysis of the entire specimen [49, 50].
