[Prostatic vasculitis, an unusual onset of panarteritis nodosa: presentation of 2 cases]. / Vasculitis prostática, una forma de inicio inusual de la panarteritis nodosa: presentación de dos casos.

Prostatic involvement in nodose panarteritis is considered as exceptional, especially as the onset of the disease. We discuss two cases which made their debut with fever, weight loss and urinary symptomatology, simulating a prostatic neoplasia. The pathology study of the ressected prostatic sample showed in both cases a necrotizing vasculitis which yielded the diagnosis of nodose panarteritis, and to establish the specific treatment with steroids an immunosuppressants.

[Pseudotumoral hepatic tuberculosis]. / Tuberculosis hepática pseudotumoral.

Liver infection as a result of tuberculosis is well known; there are several histological lesions, the most important being epithelioid cell granuloma. There are 3 anatomo-clinic variants: military or micronodular type, macronodular or pseudotumoral and pericanalicular of cholestatic. A case of a 66 year old male with a diagnosis of hepatic pseudotumoral tuberculosis, confirmed by means of a laparoscopy, is presented. The rareness of this particular presentation is discussed, as well as the difficult diagnosis due to confusion with primary or metastatic tumors of the liver.
