Papillary endothelial hyperplasia in the nose

Abstract

Benign papillary endothelial hyperplasia is a very rare lesion of the nasal cavity; histologically, it may be mistaken for an angiosarcoma. An awareness of this and the ways in which it differs from angiosarcoma will prevent incorrect diagnosis and inappropriate treatment by surgery or radiotherapy. A case report of each condition involving the nasal cavity is presented.
