Mycobacterium Abscessus Granulomatous Cystitis in a Patient With Superficial Bladder CancerMehanni, Stephen MD*; Joseph, Krista MD†; Casanas, Beata DO†; Greene, John MD†‡Infectious Diseases in Clinical Practice: March 2014 - Volume 22 - Issue 2 - p 116–117 doi: 10.1097/IPC.0b013e31828875e6 Case Reports Abstract Author Information Abstract: Mycobacterium abscessus granulomatous cystitis is exceedingly rare in the literature. However, M. abscessus is the most pathogenic of the rapidly growing nontuberculous mycobacteria (RGM) that is known to cause pulmonary disease, cutaneous infections, and other nosocomial infections. The diagnosis of nonpulmonary disease is made by tissue biopsy or culture. The various nosocomial infections caused by rapidly growing mycobacteria include catheter-related prosthetic devices and surgical site infections. We present the case of a 73-year-old man with superficial bladder cancer, who developed M. abscessus granulomatous cystitis after cystoscopic tumor resection and intravesical bacillus Calmette-Guérin infusions. The patient was successfully treated with levofloxacin and azithromycin.
