[Bladder metastases of pulmonary carcinoma. A report of 2 cases]

Metastatic vesical tumours caused by blood- or lymph-borne neoplasias from any part of the body are extremely uncommon (less than 1% of vesical tumours), and even within this group lung tumours are the origin in a very small number of cases. Diagnosis usually happens in advanced stages due to the limited symptomatology exhibited. This paper refers two cases of vesical metastatic neoplasias from lung tumours, one an oat-cell anaplastic carcinoma and one epidermoid. Also, in the first one there was the peculiarity of haematuria being the early manifestation which lead to the diagnosis of lung neoplasia.
