title: Extramedullary hematopoiesis occurring as a nasal polyp in a man with a myeloproliferative disorder.
abstract: We describe the case of a patient with a known myeloproliferative disorder who presented with epistaxis and what clinically appeared to be a nasal polyp. The mass was resected and proved to represent a focus of extramedullary hematopoiesis. The patient subsequently developed extramedullary hematopoiesis of the skin and the stomach wall. Following nasal polypectomy, he did well for a time, but he eventually died as a result of other complications of his disease. This unique case serves as a reminder that common rhinologic complaints can be a sign of significant and life-threatening pathology.
