[Interdisciplinary therapy management in malignancy of the paranasal sinus tumors in children].
BACKGROUND
Malignant tumors of the paranasal sinuses, such as rhabdomyosarcoma or Ewing's tumors, often have a mesenchymal origin. In the recent years, several prospective, randomized, multicenter studies have demonstrated a better outcome after new oncology therapy protocols.


RESULTS
In the period from January 2000 to June 2001, we operated 610 patients with sinus disease. Only 23/610 were children or teenagers (3.8%). Half of the juvenile group suffered from chronic sinusitis, but 5/23 (22%) had a malignoma of the paranasal sinuses. In the adult population, malignoma was diagnosed in less than 1% of cases. We diagnosed and treated, in cooperation with our radiology, pathology and children's hematooncology department, one rhabdomyosarcoma, two malignant peripheral neuroectodermal tumors (PNET), one myelosarcoma and one malignant lymphoma in the paranasal sinuses. Two patients died.


CONCLUSIONS
These five cases of paranasal sinus malignomas are discussed in relation to their history and clinical course. We suggest that interdisciplinary treatment involving otorhinolaryngology, pathology, children's hematooncology, radiology and radiation therapy is obligatory for the therapy and for the best possible outcome of such cases.
