[Primary signet ring cell adenocarcinoma of the bladder. Report of 2 cases of bladder plastic linitis].
OBJECTIVE
Two additional cases of signet-ring cell adenocarcinoma of the urinary bladder, an uncommon highly malignant tumor type, are described.


RESULTS
The clinical features, histopathological findings and immunohistochemical study are presented.


CONCLUSIONS
Both cases previously had cystic glandular cystitis, which supports the totipotent urothelium origin of this neoplasm. Signet-ring cell adenocarcinoma or linitis plastica of the bladder has a highly malignant course despite neoadjuvant chemotherapy and total cystectomy.
