BackgroundParaganglioma is an extra site of pheochromocytoma. Paraganglioma in the bladder is a very rare disease accounting for 0.06% of all bladder tumors.Case presentationA 77-year-old Japanese man was referred to our department for the further examination of a bladder tumor detected on preoperative computed tomography of his gastric cancer. Cystoscopy revealed a submucosal tumor in the upper area of his bladder, so transurethral resection of the bladder tumor was performed. During transurethral resection of the bladder tumor, his blood pressure sharply increased, and a pathological examination showed paraganglioma in his bladder. Postoperative I-123-metaiodobenzylguanidine scintigraphy detected a higher intake of his bladder tumor. Laboratory examinations showed a slightly increased noradrenaline level of 530 pg/ml and reduced platelet count at 167,000/μL. Based on the progression of his gastric cancer, no additional therapy was performed on his bladder tumor. Eight months after surgery, he died from aspiration pneumonitis.ConclusionsHere we report a rare case of paraganglioma in the bladder. We discuss paraganglioma based on previous studies.
Recent studies have shown that several inflammatory markers, including the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), lymphocyte-to-platelet ratio (LPR), De Retis and prognostic nutritional index (PNI), can function as useful prognostic factors in a number of malignancies. The present study aimed to assess the most reliable inflammatory tumor marker in patients with bladder cancer who have undergone radical cystectomy. A total of 161 cases underwent radical cystectomy between 1994 and 2014 at
Prostate basal cell carcinoma (PBCC) accounts for 0.01% of all prostate cancers. A 68-year-old man complained of dysuria for 5 years on his initial visit. His PSA level was 3.87 ng/mL. Due to a diagnosis of benign prostate hyperplasia, he underwent transurethral resection of the prostate. A pathological examination revealed that basal cell-like atypical cells made alveolar with palisadal layout. Immunohistochemical analysis showed positive 34β12, P63, and Ki-67. Based on these findings, PBCC was diagnosed. Then, we performed radical prostatectomy. He was free from recurrence 22 months after the operation. We herein report an extremely rare case of PBCC.
Introduction: Iatrogenic ureteral injury is sometimes seen in daily clinical practice, and gynecological surgery carries the highest risk of ureteral injury among iatrogenic surgical ureteral injury. Case presentation: A 61-year-old woman was referred to our department for right ureteral stricture and hydronephrosis after total hysterectomy. We initially attempted ureteral stenting, but hydronephrosis redeveloped 1 month after ureteral stent removal. We performed ureteroscopy via an antegrade approach and successfully incised and dilated the ureter. Conclusion: We encountered a case of severe ureteral stenosis after total hysterectomy that was successfully treated endoscopically using ureteroscopy via an antegrade approach.An antegrade ureteroscopic approach might be useful for performing balloon dilation for relieving ureteral stricture in patients in whom a retrograde approach fails. 140
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.
