Extending Horizon of Robotic Surgery to Bladder-Preserving Approach for Vesical Paraganglioma: Rare Case with Unusual Presentation.

Background: Vesical paraganglioma is rare and accounts for <0.1% of all urinary bladder tumors. They are mostly functional because of secretion of catecholamines and clinical presentation may mimic like a hyperfunctioning adrenal pheochromocytoma. They are easily misdiagnosed as urothelial malignancy and adequate perioperative attention is not provided. Case presentation: We hereby report a case of 55-year-old Indian lady with silent vesical paraganglioma at anatomically difficult location of bladder neck managed with robot-assisted excision of mass and bladder preservation. Conclusion: Surgery is the mainstay of the treatment that requires total excision of mass. However, minimally invasive bladder-preserving approach should be always kept as an option, if feasible. Robot assistance can help in bladder preservation even in difficult anatomic locations.

Neurofibromatosis of the colon: an unusual manifestation of von Recklinghausen's diseases--a case report.

Multiple neurofibromas arising in nerves are well established features of von Recklinghausen's disease. However, significant involvement of the gastrointestinal tract, especially the colon, is a rare entity. We hereby report a case of colonic neurofibromatosis.
