Introduction: Intravascular papillary endothelial hyperplasia (IPEH) is a papillary hyperplasia of the endothelial vascular cells, also called Masson's tumor. Masson's etiology and risk factors remain unclear but trauma and vascular pathologic conditions may start the tumor process from its common regions like extremities. Common presentations include swelling and mild pain. Our Radiologic modality of choice is Contrast-enhanced MRI which can help us before operating parotidectomy, the gold standard of tumor treatment. As presented in this study, Parotid Masson's tumor, is a very rare form of Masson's,making it even more exceptional. Case Report: This paper reports a case of a 29-years-old woman with a mass in herright parotid gland from 17 years ago, which has slowly increased in size during these years. She underwent a total parotidectomy following unsuccessful Fibrovein injections, which caused her inflammation. Embolization was performed before the resection to decrease the risk of its hemorrhage. Postoperative follow-up confirmed the reliability of this treatment method as the patient declared no side effects. Apart from its tough diagnosis, since Masson's tumors, especially the ones that emerge in the parotid, are rare, we decided to introduce this case to deliver more information about the treatment and diagnosis of this rare disease to other colleagues. Conclusions: The prognosis of parotid Masson's is admirable following a total resection. The patient had no postoperative complaints with no need for multiple visits after resection.
