Extramedullary plasmacytoma (EP) is a relatively rare neoplasm; about 90% of cases are localized in the head and neck area. EP has been considered a precursor of multiple myeloma but cases showing long disease free intervals or cure by surgery alone have been reported. A research of the world literature pointed out the extremely rare localization of solitary plasmacytoma in the salivary glands. Only 9 cases have been reported until now, 6 in the parotid gland, 2 in the submandibular glands and 1 in both the parotid and submandibular gland.
