Extramedullary Plasmacytoma of the Frontal Sinus

Extramedullary plasmacytoma involving the head and neck region is rare. Among the sites of involvement, nasopharynx, nasal cavity, paranasal sinus were the most frequent sites in descending order. Maxillary sinus is the most prevalent site of the paranasal sinuses with occasional involvement of the ethmoid and sphenoid sinus. However, the frontal sinus has not been reported to be the site of involvement as far as we know. Recently we experienced an extramedullary plasmacytoma of the frontal sinus in a 54 year-old male patient and report with literature review. (Korean J Otolaryngol 40:7, 1997)
