[Primary vesical adenocarcinoma with signet ring cells or linitis plastica of the bladder. Three cases]

Signet ring cell adenocarcinomas of the bladder are regarded as rare tumours. The authors actually think that their frequency is underrated since they report three new cases out of a range of 700 bladder tumours. Revealing signs consist in urgency pain, frequency and/or hematuria. This set of cancer is usually tardily diagnosed and therefore of very poor prognosis whatever the therapies.
