Head and Neck Reconstruction in Patients with Polycythemia Vera: Case Series and Literature Review.

 Polycythemia vera (PV) is a myeloproliferative disease with overproduction of erythrocytes, leukocytes, and platelets causing an increased risk of both thrombosis and hemorrhage. There are limited reports and no established guidelines for managing such patients undergoing reconstructive surgery.  We present four patients with PV and head and neck cancer who required reconstruction after resection and provide a review of the current literature.
