A 72-year-old woman underwent computed tomography (CT) to identify the underlying cause of thrombocytosis. The CT showed a bladder tumor. Urine cytology was negative. Cystoscopic examination showed a dome-shaped bulge at the right lateral wall of the bladder, suggesting a submucosal tumor. The bladder tumor was immediately resected transurethrally. The histological diagnosis was malignant lymphoma of mucosa-associated lymphoid tissue. Positron emission tomography-CT showed no lesions other than the bladder tumor. The patient was diagnosed with primary malignant lymphoma of the bladder.
The tumor was low-grade, and strict follow-up was subsequently carried out. There was no evidence of recurrence or metastasis at 13 months after treatment.
