AbstractSalivary glands are unique secretory glands due to its histological diversity and heterogeneity. More than 90% pleomorphic adenoma (PA) are found in majorsalivary gland i.e. parotid. This tumor is known to occur at various other anatomical locations apart from the major salivary glands. 8% of PAs involve the minor salivary glands of which 60-65% in the palate and 5.5% at minor salivary glands of cheek. Less frequent sites such as lacrimal gland, external auditory canal, breast and parapharyngeal space, reported sparsely in English literature. PA at breast and external auditory canal (EAC), can be challenging and may lead to a misdiagnosis, as invasive carcinoma. Involvement of parapharyngeal space are also rare and constitute less than 0.5% of head and neck neoplasm. We are presenting here a series of 10 cases of PA at unusual sites with an aim to highlight the role of FNAC, which has sufficiently high accuracy rate and can be a useful guide in making decisions for further management.
