Extramedullary plasmacytoma of the parotid gland.

A case of solitary extramedullary plasmacytoma of the parotid gland occurring in a 47-year-old male patient is reported. Clinical examination failed to reveal evidence of this neoplasm elsewhere in the body. Problems connected with the clinical, pathological and therapeutic aspects of the neoplasm with particular regard to the rare parotid location are taken into consideration. Furthermore, stress is laid on the fact that patients with extramedullary plasmacytoma should be thoroughly followed-up as multiple myeloma may occur even decades later in life. This is the fourth case of extramedullary plasmacytoma located in salivary glands to be reported in the world literature.
