Retrocaval or circuncaval ureters are rare congenital anomaly, in which the ureter is located posterior to the inferior vena cava (IVC). Usually, patients present symptoms in the 3rd or 4th decade of life due to compression of the ureter by the IVC, with obstruction of the urinary flow and consequent hydronephrosis. Herein we report the case of a 62-year-old patient who underwent ultrasonography to investigate abdominal pain. The patient had bilateral renal lithiasis associated with urinary tract dilation with no obvious obstruction. Computed tomography of the abdomen demonstrated a retrocaval ureter without hydronephrosis.
Primary urethral carcinoma is much more common in women than in men due to its association with urethritis. A 65-year-old man presented with a 10-month history of penile induration, obstructive voiding symptoms and hematuria. Urethrocystoscopy showed a solitary mass in the proximal urethra and no bladder involvement. It was performed penectomy without bladder neck excision and regional staging lymphadenectomy of the obturator lymph nodes. Pathological diagnosis revealed adenosquamous cell carcinoma with squamous and glandular components. We described a case of primary mixed glandular-endocrine tumor of the male proximal urethra consisting of adenosquamous cell carcinoma with squamous and neuroendocrine components.
Perineuriomas are benign, rare neoplasms of the nerve sheath, basically in two forms: intraneural and extraneural. Extraneural forms are mainly found in the trunk and limbs, while visceral organs are rarely affected. To date, there have been no previous reports in the literature of bladder perineurioma. In this case, we report a young adult with hematuria and bladder tumor which after surgical resection and immunohistochemical study was confirmed to be a perineurioma. Therefore, this should be included in the differential diagnosis during the analysis of resections of bladder tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
