Intranasal glomus tumor.

The glomus tumor, or glomangioma, is a hyperplastic or hamartomatous lesion of the glomus body. It is composed of vascular channels surrounded by characteristic "epithelioid" cells, which are probably derived from smooth muscle. Glomus tumors rarely occur in the head and neck. We encountered the fifth documented case, to our knowledge, of a glomus tumor presenting in the nasal cavity. Although the lesion in this case was asymptomatic, intranasal glomus tumors producing nasal obstruction, pain, and epistaxis have been described. The complete excision of a glomus tumor normally cures the condition.
