Signet ring cell adenocarcinoma of the bladder: linitis plastica variant.
An unusual case of the signet ring cell variant of adenocarcinoma of the bladder occurred in which the tumor extensively infiltrated the bladder wall and perivesical fascia. The pattern of infiltration was analogous to that seen in the linitis plastica variant of gastric carcinoma. Cystoscopic and roentgenographic studies failed to reveal a grossly evident lesion.
