Carcinosarcomas are rare biphasic malignant neoplasms with an epithelial and a spindle cell component. We present a 62-year-old man with a history of noticeably abdominal distension, proved by surgery to be caused by carcinosarcoma of the renal pelvis and urinary bladder, occupying the entire left abdominal flank. We also illustrate the appearance of this rare entity on sonography and computed ...

OBJECTIVE The purpose of this study was to evaluate the effectiveness of contrast-enhanced sonography in comparison with conventional sonography in differentiating muscle-infiltrating and superficial neoplasms of the urinary bladder. SUBJECTS AND METHODS Conventional and contrast-enhanced sonography were performed on 34 consecutively registered patients with bladder tumors. All examinations w...

As our understanding of the molecular events leading to the development and progression of genitourologic malignancies, new markers of detection, prognostication, and therapy prediction can be exploited in the management of these prevalent tumors. The current review discusses the recent advances in prostate, bladder, renal, and testicular neoplasms that are pertinent to the anatomic pathologist.

Introduction ▼ Paragangliomas are rare extraadrenal neoplasms of the sympathetic nervous system, which seldom may arise in the sympathetic plexus of the urinary bladder wall. Some of these tumors are producing catecholamines. Hormonally active paravesical paragangliomas are exceedingly rare tumors, accounting for less than 1 % of all pheochromocytomas and for less than 0.05 % of bladder tumors....

PURPOSE Bladder cancer is the sixth most common cancer in the United States, but is exceedingly rare in young patients, leading to a lack of accepted standards for diagnosis, treatment, and surveillance. We review our institutional experience with bladder urothelial neoplasms in pediatric and young adult patients summarizing presentation, treatment, and outcomes. METHODS Surgical pathology re...

This review article is devoted to the main problems of early diagnostic and prognosis non-muscle-invasive bladder cancer, which accounts for 75 % all newly detected cases cancer according statistics. Chromosomal disorders that have been in urothelial cells can lead development cancer. The highlights existing systems their disadvantage limitations use practice. Special attention given tumor stem...

One individual with two or three malignant neoplasms is not uncommon. However, a patient with more than 5 primary malignancies is unusual. We present a 51-year-old female who developed 6 metachronous primary malignant neoplasms in a period of 10 years. The anatomic sites of neoplasms in this patient included the cervix, larynx, skin, left breast, bladder and right lung (middle lobe). All of the...

BACKGROUND Sympathetic urinary bladder paragangliomas are rare catecholamine-secreting neuroendocrine tumors arising from neural crest cells. They are uncommon urinary bladder neoplasms. Symptoms classically include micturition-related or unrelated palpitations and syncope with hypertension, headaches, diaphoresis, and hematuria. Other than being attributable to vasovagal reactions, micturition...

Bladder leiomyomas are benign mesenchymal neoplasms and very rare urinary tumors that represent\0.5 % of all bladder tumors, with only 250 cases reported worldwide till date [1]. The incidence of bladder leiomyoma is 3 times higher in women than in men. Typically, it occurs in the fourth and fifth decades of life. We present here a case of leiomyoma of urinary bladder in middle-aged woman with ...

PURPOSE The aim of the present study was to define gene expression profiles of noninvasive and invasive bladder cancer, to identify potential therapeutic or screening targets in bladder cancer, and to define genetic changes relevant for tumor progression of recurrent papillary bladder cancer (pTa). EXPERIMENTAL DESIGN Overall, 67 bladder neoplasms (46 pTa, 3 pTis, 10 pT1, and 8 pT2) and eight...
