Masson's tumour, also known as intravascular papillary endothelial hyperplasia, is a rare non-neoplastic lesion of vascular origin, caused by an excessive reactive proliferation of endothelial cells in normal blood vessels or vascular malformations. It can affect any part of the body, presenting most frequently in the vessels of the head, neck and upper extremities. The authors describe the case of a 76-year-old female patient presenting an anterior cervical mass, measuring 2×2 cm, which was mobile, tender and slightly painful with no alteration of the overlying skin. Complementary study with ultrasound and computed tomography was inconclusive. Total excision of the lesion was performed with histology compatible with intravascular papillary endothelial hyperplasia.Masson's tumour is a rare and indolent non-neoplastic lesion of vascular origin, that can be easily confused with other pathological entities and misdiagnosed.Diagnosis can be a challenge; histological characterization is essential for differentiation from other lesions, such as angiosarcoma and Kaposi's sarcoma.Masson's tumour should be considered in patients presenting a single cervical mass.
