Nose and paranasal sinuses tumors are rare but their clinical signs and 
   symptom,s are nonspecific and their diagnosis usually established with
   delay. The purpose of this study  was determination of epidemiological
   status of these tumors in Hamadan.

          Patients’ records in Hamadan hospitals’ file were reviewed from 1991 to
   1998 retrospectively.

          Over all, 44 patients with these tumors were evaluated. In 81.4% nasal
   cavity and in 15.9% maxillary sinus were original site of tumor. Chief
   complaints in decreasing  order of  frequency were epistaxis , unilateral
    nasal obstruction , pain in the region of face and nose and rhinorrhea . The
   most common malignant and benign tumors were S.C.C and hemangioma
   respectively.

          The results indicated that physicians must be more careful regarding the
   clinical sign and symptoms of these tumors and in the case of clinical
   suspicion refer them for complete evaluation.
