[Leukemoid reaction as a paraneoplastic manifestation of bladder carcinoma].

Sometimes vesical malignant tumours present themselves with highly characteristic paraneoplastic signs like hypercalcemia, or more rarely like a leukaemoid reaction within the symptomatic setting typical of vesical neoplasia. We present a case of vesical urothelioma where the leukaemoid reaction was present in the diagnosis and later in the tumour relapse after the appropriate treatment.
