A man in his 40s presented with a multiple-year history of difficulty breathing through his left nostril. Several months prior to presentation, he began to experience left-sided epistaxis occurring up to 10 times per month, which was controlled with direct pressure. More recently, a friend noticed bulging of his left lateral nasal sidewall. Physical examination revealed a large submucosal mass with prominent superficial vessels within the mucosa almost completely filling the left anterior nasal cavity.
