Abstract

We report a rare case of metastatic epithelioid haemangioendothelioma from an unknown primary site presenting with axillary lymph node metastases. The patient also had a new-onset membranous glomerulonephritis and thromboembolism, which we postulate were paraneoplastic. The pathogenesis of this rare cancer, the risk of misdiagnosis and membranous glomerulonephritis as a paraneoplastic syndrome are discussed.
