A 53-year-old man with dysuria, pyuria, and genital ulcers.
History of the present illnessThe patient developed dysuria and pain at the base of the penis 1 month before presenting to an outside hospital. His pain worsened and he developed fever, pyuria, and penile ulcers a couple of days prior to admission. The patient also noted light pink urine, which was concerning for hematuria. He was treated empirically for both chlamydia and herpes simplex virus (HSV) infections with doxycycline and acyclovir, respectively, but urine polymerase chain reaction assays for Chlamydia trachomatis and Neisseria gonorrhea were negative and a penile ulcer swab was negative for HSV. His diagnosis was amended to prostatitis and he was discharged on levofloxacin. Amoxicillin was added after his urine culture grew a group B Streptococcus species.He followed up in the urology clinic as an outpatient and underwent a transrectal ultrasound of the prostate, the results of which were not consistent with prostatitis. A computed tomographic scan of the pelvis with contrast demonstrated mild thickening of the bladder wall and perivesical stranding consistent with inflammation. He continued to have painful urination and pyuria, for which he was readmitted to the hospital 3 weeks later.During his second hospital admission, he underwent repeat cystoscopy that revealed a large necrotic mass at the bladder trigone. The mass obstructed both ureteral orifices. Transurethral resection of the trigonal mass was performed, with bilateral ureteral stent placement. Histologic examination of the surgical specimen was notable for acute suppurative inflammation and necrosis, without evidence of malignancy.Ulcerative lesions on the glans penis persisted. These were retested for HSV as well as for Lymphogranuloma venereum and Treponema pallidum, but all of these assays were negative. He was prescribed a topical glucocorticoid, which seemed to decrease the size of the ulcers.During his admission, his serum creatinine rose from baseline of 1.2 to 4.0 mg/dl. His acute kidney injury was attributed to the combination of contrast-induced renal injury and obstructive uropathy from his resected trigonal mass. His creatinine improved but did not normalize following placement of ureteral stents. He developed a fever to 1018F and was started on piperacillin and tazobactam with no clear genitourinary source of infection. An extensive serologic evaluation demonstrated that the patient was negative for rheumatoid factor, antinuclear antibodies (ANAs), cyroglobulins, human immunodeficiency virus infection, hepatitis A, B, and C, and anti-neutrophil cytoplasmic antibodies (ANCA). The serum angiotensinconverting enzyme concentration was normal. Cultures of his penile lesion grew few yeast, but were otherwise unremarkable. The patient was then transferred for further evaluation.The patient was admitted to the urology service with diagnoses of obstructive uropathy by a bladder mass of unknown etiology, pelvic pain, and penile ulcers. Examination of the urine sediment revealed n...
