Paragangliomas, uncommon tumors in the head and neck region, are especially rare in the nasal cavity. The authors have experienced a case of nonchromaffin paraganglioma in the nasal cavity. To our knowledge, this case report is the 3rd in Japan and there have been seventeen reported cases in the literature. The patient, a 16-year-old man, had complained of left recurrent epistaxis since December 1994 and was referred to our hospital in May 1995. On physical examination, a polyp-like mass was noted on the anterior surface of the left middle turbinate.<BR>The mass had a rich capillary network and tended to bleed easily. Paranasal sinuses x-rays were normal, except a tumor-like shadow found in the left nasal cavity. Computed tomography demonstrated a small mass in the left nasal cavity and marked contrast enhancement. After external carotid angiography and embolization, a surgical operation was done. Histopathological diagnosis of paraganglioma was made because of the typical finding of "Zellballen" pattern.<BR>Paraganglioma is a benign tumor but has the potential of local recurrence, lymph node metastasis and distant metastasis, so it requires a long-term follow-up.
