title: [Atypical localization of a small cell carcinoma in the paranasal sinus area--case report].
abstract: 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 undifferentiated carcinomas. Extremely rare are small cell carcinomas localized in the paranasal sinuses.
  
  
  METHODS
  A 60-year-old male patient was seen in February 1996 in our ENT Department with unspecific pain on the left maxillary sinus and alveolar ridge. Anterior rhinoscopy revealed an extended tumor on the left nasal fossa; histopathological examination showed a small cell carcinoma. No other primary tumors or metastases were detected in extended staging. Due to the extended paranasal tumor as well as the histopathological findings, the patient was given induction chemotherapy followed by radiation therapy.
  
  
  RESULTS
  To date (4/97), we achieved partial remission without any clinical complaints.
  
  
  CONCLUSIONS
  The therapeutical result is comparable to other therapeutical regimens.
