RESUMEN
PURPOSE: Viral infections are a major cause of postoperative morbidity and mortality after renal transplantation. Although cytomegalovirus, Epstein-Barr virus, and polyoma virus infections are common, there have been only a few reports of adenovirus infections. MATERIALS AND METHODS: We report an unusual case of a patient with adenovirus-induced hemorrhagic cystitis (AHC). We also performed a comprehensive MEDLINE review to identify similar cases. We then compared the presentation, management, and outcome of all patients to identify patterns that may facilitate the diagnosis and management of AHC. RESULTS: Review of the literature revealed 36 other reported cases of AHC in renal transplant recipients. Thirty-six of the 37 cases occurred within 1 year of transplantation. These patients presented with fever, dysuria, hematuria, and graft dysfunction. Thirty-four received high-dose steroids for treatment of symptoms of acute rejection. Four patients received antiviral medications. The infection was self-limited with mean duration of symptoms being 20 days. In all cases, serum creatinine returned to baseline or near baseline levels with resolution of symptoms. CONCLUSIONS: Although uncommon, AHC usually presents within 1 year of renal transplantation with a consistent constellation of symptoms. The infection appears to be self-limited with full recovery in most patients within 4 weeks. The efficacy of antiviral medications could not be determined in this review.

A pulmonary metastasis of prostate cancer in the absence of osseous or lymph node metastases is an extremely rare finding. We report the case of a 49-year-old man with a history of stage T2CN0M0 prostate cancer who had undergone a radical perineal prostatectomy and laparoscopic lymph node dissection, pelvic radiotherapy, and hormonal manipulation. He developed a solitary pulmonary nodule with a negative bone scan and computed tomography of his chest, abdomen, and pelvis. As a result, he underwent an open biopsy and lobectomy. The final pathology of the specimen was consistent with a metastatic lesion that stained positive for prostate-specific antigen. We present this unusual case and a review of the small number of similar cases that have been reported.
