SMALL-CELL CARCINOMA OF THE PARANASAL SINUSES - CASE-REPORT

Background: Malignant neoplasms of the paranasal sinuses are estimated at 3 to 5% of all head and neck malignant neoplasms. More than 50% of the cases are classified as squamous cell or anaplastic undifferentia ted carcinomas. Extremely rare are small cell carcinomas localized in the paranasal sinuses. Method and patient: A 60-year-old male patient was seen in February 1996 in our ENT Department with unspecific pain o n the left maxillary sinus and alveolar ridge. Anterior rhinoscopy rev ealed an extended tumor on the left nasal fossa; histopathological exa mination showed a small cell carcinoma. No other primary tumors or met astases were detected in extended staging. Due to the extended paranas al tumor as well as the histopathological findings, the patient was gi ven induction chemotherapy followed by radiation therapy, Results: To date (4/97), we achieved partial remission without any clinical compla ints. Conclusions: The therapeutical result is comparable to other the rapeutical regimens.
