Between 1998 and 2001, several cases of ataxia and paresis followed by recumbency and death were reported in cows from different farms in a restricted area of the Argentinian Patagonia. Five cases of this cluster were studied and a diagnosis of malignant schwannoma was established. Electron microscopy (EM) of tumour samples from three of the animals revealed intracytoplasmic or interstitial structures resembling retroviral particles. Attempts to isolate a viral agent from the tumours were unsuccessful but the epidemiological data and the EM findings suggest a viral aetiology.
