Intravascular Papillary Endothelial Hyperplasia (Masson's Tumor): Diagnosis the Plastic Surgeon Should Be Aware of.

Abstract

Summary:Intravascular papillary endothelial hyperplasia (IPEH) or Masson’s tumor is a rare benign entity commonly found on the head, neck, and upper extremities. It usually arises within a blood vessel but is considered to be a nonneoplastic reactive process often associated with vascular injury. Typically, IPEHs cause no symptoms and present as slowly growing soft-tissue masses. Given their prevalent location and indolent clinical presentation, the plastic surgeon should be familiar with this rare entity. We are presenting a case of IPEH of the forehead with unusual clinical and pathologic characteristics. Differential diagnosis, special considerations regarding preoperative work-up, and treatment options are discussed.
