Abstract
Primary lymphoma of the bladder is rare and may present with nonspecific symptoms and infection. Primary follicular lymphoma of the bladder is extremely rare with only a dozen reported cases. We present one case clinically mimicking an inflammatory process. A 79 year-old woman presents with recurrent urinary tract infections, urinary incontinence and frequency. Cystoscopic examination demonstrated a raised but flat lesion, suspicious for inflammatory lesion. Biopsy revealed a diagnosis of follicular lymphoma, grade 1-2. The presentation of primary follicular lymphoma of the bladder may be nonspecific, therefore it is important to consider this diagnosis in patients with unremitting symptoms.
