[Differential diagnosis of destructive processes of the skull base. Aggressive polypoid eosinophilic pansinusitis with expression of carcinoembryonic antigen (CEA)].
We report a woman with extensive polypoid sinusitis and bony destruction of the middle and posterior skull base. Histological examination of the specimen from the paranasal sinuses and adjacent skull base revealed polypoid eosinophilic sinusitis: malignancy could be excluded histologically and clinically. Plasma-CEA-levels were elevated to 85 micrograms/l with no typical source of CEA expression, and they fell after therapy. Immunocytochemistry revealed a remarkable expression of CEA in the surface epithelia of the specimen obtained from the paranasal sinuses. CEA-immunoscintigraphy showed an enhancement in the regions of the paranasal sinuses without expression elsewhere in the body. The authors discuss the possibility of using CEA as a marker for aggressive forms of chronic sinusitis and suggest radiotherapy is a successful treatment option in addition to surgery. The observation period of almost two years confirms the value of the chosen therapy.
