Abstract Osteosarcoma is a very rare tumor of the urinary bladder, with only 28 well-documented cases reported in the literature to date. The tumors have characteristically been large and polypoid and most commonly have been located in the trigone. An abdominal mass has occasionally been palpated, and rectal examination has frequently revealed a mass in the region of the bladder. The prognosis for this tumor is very poor. In this report, a 75-year-old man with hematuria was found to have a primary osteosarcoma of the urinary bladder with superficial invasion. Radical cystoprostatectomy and ileal conduit urinary diversion were performed. During surgery, a synchronous mucinous adenocarcinoma of the ascending colon was found, and a right hemicolectomy was performed. Prostatic adenocarcinoma was discovered from the histology. The patient died 7 months after surgery with systemic spread of the osteosarcoma. Osteosarcoma of the bladder should be distinguished from other bladder tumors that may be associated with bone formation, such as carcinosarcomas and transitional cell carcinomas with osseous metaplasia of their stroma, both of which have a better prognosis than osteosarcoma.

Immunohistochemistry for uroplakin III (UP III), cytokeratin 7 (CK 7), and cytokeratin 20 (CK 20) using commercially available antibodies was done in normal canine urinary bladder and 72 canine urinary bladder tumors that had been fixed in formalin and embedded in paraffin. Prolonged fixation (3–28 days) did not significantly alter the immunostaining for UP III. There was moderate reduction in the intensity for CK 7 and CK 20 after 1 week of fixation. UP III was detected in superficial (umbrella) cells and some intermediate cells of the normal urinary bladder, 7 of 7 transitional cell papillomas (TCPs), 50 of 55 transitional cell carcinomas (TCCs), and 4 of 5 metastatic TCCs. Staining was typically outlined in the plasma membrane, but diffuse or focal cytoplasmic staining was also observed. Intracytoplasmic lumina were usually positive for UP III. One squamous cell carcinoma of the bladder, 4 nonepithelial bladder tumors, and 285 nonurothelial tumors from different nonurinary locations were negative for UP III. CK 7 was detected in 7 of 7 TCPs, 53 of 54 TCCs, and 5 of 5 metastatic TCCs. The staining for CK 7 was diffuse cytoplasmic. CK 20 was detected in 1 of 7 TCPs, 37 of 54 TCCs, and 1 of 5 metastatic TCCs. The staining with CK 20 was cytoplasmic and weaker than with antibodies to UP III or CK 7. There was concurrent expression of UP III, CK 7, and CK 20 in 36 of 54 TCCs. UP III is a specific and sensitive marker for canine transitional epithelial (urothelial) neoplasms, detecting 91% of TCCs. Negative results may be observed with anaplastic tumors.

Background:  Urinary bladder lesions are the main source of significant clinical symptoms which are more disabling than lethal. Bladder tumors constitute one of the most common urological pathology. Urothelial carcinoma accounts for 90% of all primary tumors of the bladder. This study aimed to determine the frequency of different types of lesions of the urinary bladder and to determine the grade and stage of urothelial tumors.Materials and Methods: This is a 2 years cross sectional study of cystoscopic biopsies carried out in the Department of Pathology, Medicare National Hospital and Research Centre, Kathmandu, Nepal.Results:  Out of 87 cases, 58 (66.67%) cases were neoplastic lesions and 29(33.33%) cases were non- neoplastic lesions. Majority of neoplastic lesions 96.55% were urothelial (transitional cell) tumors comprising predominantly of low grade papillary urothelial carcinoma 50.91%. Muscle invasion was seen only in high grade papillary urothelial carcinomas.Conclusion: Among bladder tumors low grade papillary urothelial carcinoma is the most common.

Mesenteric Cysts

Introduction Mesenteric cysts are rare intra-abdominal masses. They do not show classic clinical findings and are detected incidentally during imaging because of their absent or nonspecific clinical presentation. We herein report 2 cases of mesenteric cysts that were successfully diagnosed and resected through a laparoscopic approach. Case presentation In a 35-year-old man underwent a comprehensive medical checkup at another hospital, during which ultrasound incidentally revealed a cystic mass in his right retroperitoneum. The patient was referred to our hospital for surgical treatment. He was asymptomatic and his medical history was unremarkable. Physical examination revealed no palpable abdominal mass, and all laboratory test results were within normal ranges. Contrast-enhanced computed tomography showed a 7.2-cm-diameter smooth-surfaced, well-demarcated mass behind the right colon without a contrast effect (Fig. 1). We considered the cyst to be benign and localized in the mesentery of the ascending colon. In one patient, the cyst was located in the mesentery of the ascending colon and removed via a right hemicolectomy; in the other patient, the cyst was located in the sigmoid mesentery, which was completely resected through the operative wound under an open procedure after laparoscopic mobilization of the sigmoid mesentery. We chose the laparoscopic approach in both cases because the cysts were considered benign, noninfectious, and nonhemorrhagic. Histologic examination revealed cystic lymphangioma in both cases. Conclusion For mesenteric cysts, laparoscopy could be a preferred approach in properly selected patients.

Objective: To report our experience in performing laparoscopic radical cystectomy with ileal conduit urinary diversion (extracorporeal reconstruction). Material & method: This study was take place in Hasan Sadikin Hospital Bandung. A 54-year-old male with histologically proven transitional cell carcinoma of the bladder cT2bN0M0 underwent a laparoscopic radical cystoprostatectomy and ileum dissection was performed under laparoscopy. Ileal conduit and stoma reconstruction performed extracorporeal through small incision between ports (about 4cm). Results: The surgical margins were free of disease. The operative time was 360 minutes. Estimated blood loss was 600cc. Hospital stay was 5 days. Patient was discharge with no complication of post-op wound, and urine production about 1500cc/24hrs via stoma. Conclusion: Laparoscopic radical cystectomy with ileal conduit extracorporeal reconstructive urinary diversion could be the preferred means in managing bladder tumor on selective case.
