title: Primary urinary bladder mucosa associated lymphoid tissue type lymphoma presenting as a close mimic for genitourinary tuberculosis: Case report and review of literature.
abstract: Primary lymphoma of the urinary bladder is a rare entity. It has a distinctively different presentation than the urothelial carcinoma, which is the most common form of bladder cancer, but might mimic inflammatory lesions such as tubercular cystitis, clinically as well as radiologically. We present a case of primary extranodal marginal zone lymphoma of the bladder, which was a close mimicker of tuberculosis, leading to delay in diagnosis. We highlight the role of biopsy in prompt diagnosis of these cases. We emphasize on the high index of suspicion required to identify such cases at an early stage, which has pronounced prognostic implications.
