The glomangioma, a benign vascular tumour, derived from the cutaneous glomus bodies, should not be confused with paragangliomas, which are occasionally also referred to as glomus tumours. Up to now, only eleven cases of a glomangioma of the nasal cavity and the paranasal sinuses have been published. We report the case of a patient with a glomangioma of the ethmoidal aircell system. The tumour was completely removed under endoscopic-microscopic vision via endonasal access. A tumour recurrence was not observed over a period of eighteen months. The clinical signs, diagnosis, therapy and histological features will be discussed with reference to the literature.
