Masson’s Tumor

Masson’s tumor, also known as intravascular papillary endothelial hyperplasia (IPEH), is a rare benign vascular lesion characterized by the proliferation of endothelial cells within blood vessels. This condition often presents as a painless mass or nodule and can occur in various parts of the body, including the skin, soft tissues, and oral cavity. In this article, we will provide a comprehensive overview of Masson’s tumor, covering its definition, causes, symptoms, diagnosis, and treatment options.

Masson’s tumor, or intravascular papillary endothelial hyperplasia (IPEH), is a non-malignant vascular lesion that arises from the abnormal proliferation of endothelial cells within blood vessels. First described by Pierre Masson in 1923, this condition typically forms papillary structures within the lumen of blood vessels, leading to the development of a distinct mass or nodule.
