title: [Secondary paraneoplastic polycythemia of testicular cancer].
abstract: The authors report the case of a 41-year old patient with polycythaemia and a mixed testicular tumour (seminoma with choriocarcinomatous contingent). The demonstration of a raised erythropoietin level in the tumor tissue with a high gradient in relation to the serum argues in favour of secondary paraneoplastic polycythaemia. With a follow-up of 5 years, the patient is still in complete remission from his two diseases. This case may represent the first case of testicular tumour responsible for secondary polycythaemia.
