Intermittent claudication caused by a Masson tumour of the thigh: case report

Abstract Masson’s tumor, also known as intravascular papillary endothelial hyperplasia, is a rare condition characterized by nonspecific clinical manifestations, which frequently lead to its misidentification as malignant neoplasms such as sarcoma. A definitive diagnosis is established through histopathological examination. This report describes a case of a patient presenting with a mass in the left thigh accompanied by intermittent claudication of the ipsilateral lower limb, who was subsequently diagnosed with Masson’s tumour​ following surgical intervention.
