title: [Linitis plastica type of primary signet cell adenocarcinoma of the bladder].
abstract: Primary adenocarcinoma represent 0.5 to 2% of all bladder tumours and are classified according to whether or not they are derived from the urachus, although, histologically, this classification now appears to be obsolete. The authors report a very rare case of linitis plastica type of primary signet cell adenocarcinoma of the bladder in a 53-year-old patient. This carcinoma, with very unusual histological features, needs to be distinguished. Due to the delayed diagnosis, it has a poor prognosis despite the most aggressive treatment modalities, as reported in the literature. The elevated CA 19-9 observed in the present case may be a useful marker for follow-up.
