ABSTRACT
A 68-year-old female presented with macroscopic hematuria. Cystoscopy revealed a wide-based submucosal mass. Computed tomography revealed a 3.5 × 2.5-cm solitary mass situated from the trigone to the left lateral bladder wall and the left hydroureter and hydronephrosis. T2-weighted magnetic resonance imaging (MRI) revealed low intensity, and diffusion-weighed MRI showed increased diffusion without invasion. The bladder tumor was immediately resected transurethrally. Histological diagnosis of the tissue obtained by transurethral resection was extranodal marginal zone B cell lymphoma of MALT. Positron emission tomography-CT showed no lesions other than the bladder tumor. The patient was diagnosed with stage-IE lymphoma of the bladder (Ann Arbor classification). Radiotherapy was performed at the bladder and pelvis (30 Gy) with six courses of rituximab (375 mg/m2). No local or distant recurrence after a 48-month follow-up was noted.

We report a case of 2,8-dihydroxyadenine (DHA) urolithiasis in a 65-year-old male. He initially visited another institution because right hydronephrosis was revealed in a medical checkup. Computed tomography demonstrated radiolucent right renal stones. We performed percutaneous nephrolithotripsy and flexible transurethral lithotripsy and removed the stones successfully. An analysis of the stone fragments revealed 2,8-DHA urolithiasis. 2,8-DHA stones are relatively rare and caused by adenine phosphoribosyltransferase deficiency.

A 54-year-old man presented with slight pain and swelling of the right scrotum. On performing scrotal ultrasonography, the right testis showed swelling and diffused hypoechogenicity compared with the left normal testis. T2-weighted magnetic resonance imaging (MRI) revealed swelling and low intensity areas in the right testis. Diffusion-weighted MRI revealed increased diffusion in the right testis. A testicular tumor was suspected and right high orchitectomy was performed. Histopathological diagnosis was granulomatous orchitis. To our knowledge, this is the 22nd case in Japan.
