Specific Symptoms

Paraganglioma is a rare neuroendocrine tumor that arises from the autonomic nervous system. The urinary bladder paraganglioma accounts for less than 0.1% of bladder tumors. It remains a challenging entity to diagnose and treat due to its rareness and the lack of specific symptoms. Treatment modalities include transurethral resection and cystectomy (partial or total). The authors report a new case of an isolated paraganglioma of the urinary bladder in a 52-year-old female patient that underwent partial cystectomy. This case aims to remind the clinical, histological and therapeutic features of this rare tumor.

Pheochromocytoma of the bladder is a rare bladder tumor. We report a case of an 80-year-old female who presents with recurrent bladder tumors consistent with pheochromocytoma of the bladder, discovered 10 years post-resection of a prior pheochromocytoma of the urinary bladder. She was treated with partial cystectomy and was found to be symp tom free at 6-month follow-up.

Abstract Objective To investigate the feasibility and efficacy of carrying out pediatric laparoscopic partial cystectomies (LPC) when treating benign bladder tumors and urachal cysts. Methods Retrospectivey analyzing 4 clinical cases involving children with bladder tumors, which were collected from October 2017 to December 2018. In these clinical cases, there were 3 male children and 1 female child, aged from 4.5 to 9.4 years old, with an average age of 6.5 years. An intraperitoneal laparoscopic partial cystectomy was performed in the treatment of 3 of these patients with benign bladder tumors and in 1 patient with an urachal cyst. The surgical procedures included a partial cystectomy and a complete intracavitary bladder suture. Results All 4 cases were successful and no operation was transferred to opensurgery. The operation time was 100–120 min, with an average time of 108 min. The intraoperative blood loss was 10–20 ml, with an average loss of 15 ml. 6 h after the operation, the patients still maintained a fluid diet and 1 case of hematuria had occurred, with the catheter removed 12 days after the operation. No postoperative urine leakage, intestinal adhesion or intestinal obstruction occurred, and the average postoperative hospitalization time was 14 days. Conclusion Laparoscopic partial cystectomy is a safe and feasible method to be used for the treatment of benign bladder tumors and urachal cysts. It presents the advantages of being minimally invasive, and having a quick recovery and short hospitalization time. It is an alternative surgical method for the treatment of pediatric benign bladder tumors.

Objective: This study presents our initial experience with extraperitoneal and transperitoneal laparoscopic partial cystectomy (LPC) in the treatment of benign non-urothelial bladder tumors. Methods: Eleven patients with benign non-urothelial bladder tumors underwent extraperitoneal or transperitoneal LPC. The five cases with tumors located on the anterior/anterolateral bladder wall received the extraperitoneal approach. The six cases with tumors located around the bladder dome or over the posterior bladder wall received the transperitoneal approach. Key perioperative parameters were recorded. Results: All patients underwent laparoscopic resection smoothly without requiring a conversion to a traditional open procedure, and no patient displayed perioperative complications. Pathology showed benign non-urothelial bladder tumors with normal margins in all eleven patients, including five leiomyoma cases, three pheochromocytoma cases, two paraganglioma cases and one inflammatory fibrous histiocytoma case. Follow-up cystoscopy and imaging studies in all eleven patients (mean follow-up period 32 months) revealed neither residual nor local recurrence. Conclusions: LPC is safe and feasible in select patients with benign non-urothelial bladder tumors and yields satisfactory oncological and functional results. Extraperitoneal LPC should be preferred for lesions located on the anterior/anterolateral bladder wall, while transperitoneal LPC should be preferred for lesions around the bladder dome or over the posterior bladder wall.

Invasive Carcinomas

Clinical and morphological characteristics of 139 naturally occurring and 20 bracken-fern-induced urinary bladder tumors of cows were studied. Hematuria was prominent and occurred as early as 60 days after bracken fern feeding began. Anemia and changes in leukocytes were late manifestations. Papillomas appeared as early as 1 year, whereas invasive carcinomas did not develop until 2.6 years after initiation of feeding. Twenty of 30 cows fed bracken fern developed bladder tumors within 5.3 years. None of eight untreated control cows that lived 4 years or six that lived 10 years developed neoplasms. Naturally occurring and fern-induced bladder tumors were epithelial (35%) or mixed epithelial and stromal (55%). Papillomas occurred in 24% and carcinomas in 61% of naturally occurring cases, whereas there were papillomas (40%) and carcinomas (50%) in fern-fed cows. Naturally occurring tumors were metastatic to regional lymph nodes and lung. No metastases were detected in fern-fed cows.

Uncertain Etiology

Atrophic rhinitis in swine is a disease of uncertain etiology in which infectious agents, hereditary predisposition, and metabolic disturbances have been reported to be of primary etiologic importance. It shares many similarities, both clinically and pathologically, with ozena in man. The disease is characterized by deformity and reduction in volume of the nasal turbinates. The fundamental cause for the localized lesion of bone in the nasal turbinates has not been established. Reduced osteogenesis, increased resorption related to inflammation of the nasal mucous membrane, and excessive resorption due to osteocytic osteolysis stimulated by hyperparathyroidism have been suggested as possible pathogenetic mechanisms.The objectives of this investigation were to evaluate ultrastructurally bone cells in the nasal turbinates of pigs with experimentally induced atrophic rhinitis, and to compare these findings to those in control pigs of the same age and pigs with the naturally occurring disease, in order to define the fundamental lesion responsible for the progressive reduction in volume of the osseous core.
