Intravascular papillary endothelial hyperplasia (masson tumor) of the right wrist: A case report and literature review

Abstract

Intravascular papillary endothelial hyperplasia (IPEH), also called masson tumor which is a benign vascular tumor named after Pierre Masson, the French pathologist who originally described it in 1923, terming it “hémangioendothéliome végétant intravasculaire.” It is characterized by a reactive proliferation of endothelial cells associated with thrombosis. Ultrasound and MRI are the main imaging examinations, but the diagnosis of IPEH was confirmed by biopsy pathology and immunohistochemistry. It is generally accepted that surgical excision is the first choice of treatment. In this report, we report a case of Masson tumor arising in the right wrist.
