We report on a patient with an intravesical mass consisting of hyperplastic follicles in mucosa‐associated lymphoid tissue. Computed tomography and ultrasonography revealed two intravesical masses measuring 3.5 cm and 1.5 cm along the long axis. Imaging diagnosis was invasive tumors of the bladder. However, the pathological diagnosis on transurethral bladder tumor biopsy was a lesion in lamina propria consisting of hyperplastic follicles and lymphatic infiltrate between them with no cell atypia. Light microscopically, the lesion was considered to be reactive follicular hyperplasia. Antibiotic therapy resulted in an almost complete disappearance of the tumors. Such large follicular hyperplasia in the lamina propria of the bladder is rare.
