Abstract
Intravascular papillary endothelial hyperplasia (IPEH) is a benign, highly vascularized, endothelial growth that can be mischaracterized as a malignancy. While hundreds of IPEH cases are reported, only four occurred in the maxillary sinus. We present the case of a 28-year-old male who underwent surgical resection of IPEH of the right maxillary sinus. An additional consideration was the patient’s condition of univentricular tricuspid atresia which contributed to chronic hypoxemia and polycythemia. After complete resection from the maxillary sinus, post-operational workup determined the lesion to be IPEH. Given the potential for misdiagnosis of IPEH, careful histopathologic evaluation is required in order to avoid improper treatment.
