1). Surgical resection margins were free of tumor cells. The tumor was classified pT3N0M0. The patient had no adjuvant treatment. The patient consulted again after 16 months for hematuria and perineal pain. Endoscopy showed Modulators stenosis of the anterior urethra and the biopsy confirmed tumor relapse in the urethra. Radiotherapy at PS-341 clinical trial a dose of 64 Gy was delivered:

the first dose of 44 Gy at 5 fractions of 2 Gy/wk in the pelvis and then an additional 20 Gy in a limited volume in the urinary bladder. The patient was followed up every 6 months, and a thoracoabdominal CT scan was done every 6 months. The patient has radiological stability and kept a preserved quality of life after 3 years of follow-up. A 64-year-old patient without medical history consulted with a history of 2 months of total hematuria. Pelvic ultrasound showed an infiltrating mass in the posterolateral wall of the urinary bladder associated with a left hydroureteronephrosis. Cystoscopy showed a pseudopolypoid mass on the left posterolateral urinary bladder. Endoscopic resection of the tumor was performed. Pathologic examination found a poorly differentiated invasive signet ring cell adenocarcinoma. An abdominal CT scan showed a large effusion occupying

the entire abdomen and peritoneal cavity without evidence of peritoneal carcinomatosis. The buy Docetaxel digestive exploration (gastroduodenoscopy and colonoscopy) showed no suspicious location. The evolution was marked by the appearance of ascites. Cytologic analysis of the peritoneal fluid revealed the presence of neoplastic cells (Fig. 2). Palliative chemotherapy has been proposed but not performed because of the deterioration in the general condition of the patient. He was followed in the palliative care consultation. The patient died 5 months after diagnosis. Primitive bladder adenocarcinoma accounts for only 0.5%-2% of all primary malignant tumors of the bladder.1

Most adenocarcinomas of the urinary bladder result from direct extension from adjacent organs (eg, colon, prostate). Rarely, there can be metastatic spread to the bladder of SRCC originating in another organ.2 The variant signet ring cell is a poorly differentiated form, Adenylyl cyclase is exceptionally described, and its incidence is about 0.24% of bladder cancers.2 Hematuria, which was the reason for consultation in all our patients, is the most common clinical presentation. Other symptoms that have been reported are dysuria, pollakiuria, and urinary incontinence or retention.3 It is essential to distinguish this carcinoma from metastases as different therapeutic strategies are often necessary. Primary SRCC of the urinary bladder has the same histology as that of the gastrointestinal tract, breast, lung, and prostate; therefore, further evaluations for other primary sites are mandatory to exclude metastasis.
