Focal, Extranodal Primary Polymorph Hemangioendothelioma Treated With Endovascular Embolization Plus Open Surgery Resection: Rare Case Report and Review
Abstract Background: We report the rare case of an adult with a primary extranodal polymorphous hemangioendothelioma at dorsum, treated with endovascular coiling followed by open surgery resection. Clinical history, findings of spinal arteriography, histopathological findings and combined surgical procedure are reported.Case report: A 22-year-old male patient complained of a dorsal mass that has been increasing in size, painful, soft, no mobile and without neurological symptoms. A vascular tumor was suspected and an endovascular followed by an open surgical approach was performed. Histopathological diagnosis of an extranodal polymorph hemangioendothelioma was documented and a total resection was confirmed by free-tumor resection margin. The postoperative course was uneventful. Conclusion: Polymorph hemangioendothelioma is a rare vascular tumor. given the high vascular features of the lesion and, therefore, the high rate of bleeding during surgery.
