Epithelioid hemangiosarcoma is a specific variant of hemangiosarcoma that has recently been recognized in domestic animals. These malignant vascular neoplasms histologically resemble, and may be mistaken for, carcinomas. Four epithelioid hemangiosarcomas in the urinary bladders of 4 cows with severe enzootic hematuria are described in the current study. Grossly, the vesicular mucosa of the urin...

Objective: To evaluate programmed death-ligand 1 immunohistochemical expression in the available variants of urinary bladder carcinoma, and to correlate its with clinicopathological features.Method: The retrospective study was conducted at Faculty Medicine, Kafrelsheikh University, Egypt, from February 2020 April 2021, comprised formalin-fixed paraffin-embedded specimens carcinoma belonging pat...

Treatment of pelvic neoplasms with radiotherapy may develop sequelae, especially RHC. An 85-year-old male patient was admitted to a hospital emergency with gross hematuria leading to urinary retention and was diagnosed with RHC. The urinary bladder was probed, unobstructed, and maintained in continuous three-way saline irrigation. During 45 days of hospitalization, the patient underwent two cys...

breast cancer is the most common cancer in women except skin cancer. the common metastatic sites include lymph node, lung, liver and bone. however, metastasis to the bladder is extremely rare. to our knowledge, this is the first case of breast cancer metastasis to urinary bladder in jordan which is reported. nine years after the initial diagnosis of lobular breast carcinoma, the patient suffere...

The modifying effect of four dose levels of butylated hydroxytoluene (BHT) on liver and bladder carcinogenesis by A/-2-fluorenylacetamide (FAA) was studied in rats. FAA (200 ppm) was fed simultaneously with four levels of BHT (300, 1000, 3000, and 6000 ppm) to male F344 Fischer strain rats. Groups of animals were killed at 6, 12, 18, and 25 weeks. Hepatocellularaltered foci in the liver were id...

The modifying effect of four dose levels of butylated hydroxytoluene (BHT) on liver and bladder carcinogenesis by N-2-fluorenylacetamide (FAA) was studied in rats. FAA (200 ppm) was fed simultaneously with four levels of BHT (300, 1000, 3000, and 6000 ppm) to male F344 Fischer strain rats. Groups of animals were killed at 6, 12, 18, and 25 weeks. Hepatocellular-altered foci in the liver were id...

thirty clinical cases of obstructive urolithiasis, 15 with intact urinary bladder and 15 with ruptured urinary bladder, were used to study the changes in peritoneal fluid cytology. the percentage of neutrophils was highly increased than the normal reference range reported for cattle with slight decrease in lymphocyte percentage. the value for neutrophil percent was almost similar in both intact...

There is a well-documented relationship between urinary bladder diverticula and intradiverticular neoplasms. The great majorities of these tumors are urothelial carcinomas, but may also be of glandular or squamous type. Sarcomas occurring within bladder diverticula are exceptionally rare and highly malignant lesions, with only 20 well documented cases published in the literature to date (includ...

UNLABELLED Perivascular epithelioid cell neoplasms (PEComas) of the urinary bladder are extremely rare and the published cases were comprised predominantly of middle-aged patients. Herein, the authors present the first urinary bladder PEComa occurring in an adolescent. This 16-year-old Chinese girl present with a 3-year history of abdominal discomfort and a solid mass was documented in the urin...
