A RARE CASE OF MEDIASTINAL MASSON'S TUMOR MIMICKING A THYMOMA.
Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH) is a rare non-malignant pseudotumoral disease, arising in different anatomic sites, that can clinically and radiologically mimic various benign and malignant tumors. We report the first case in the literature of a mediastinal Masson's tumor, mimicking a thymoma, in a 48-year old man, successfully treated with surgery. Though surgical removal may be technically difficult due to the intrinsic hypervascularized nature of these pseudotumoral benign lesions, resection is generally recommended as they represent a locus minoris resistentiae of blood vessels, potentially causing fatal bleedings.
