Case title: Cool Case 1: Urinary bladder mass in a young man
Clinical Summary:

The patient is a 33-year-old gentleman with a history of cystic fibrosis, who had undergone a bilateral lung transplant in 2007 and two consecutive kidney transplants in 2007 and 2012. The first allograft kidney failed due to BK virus infection. He developed BK viremia after the second kidney transplant was detected 5 months posttransplant, when titers gradually increased to 84,525 copies/mL by BK virus DNA quantitative PCR. A year after his second kidney transplant, he presented with dysuria and cystoscopy examination showed a 4.5 cm sessile mass on the lateral anterior to posterior bladder wall near the ureteral orifice, although it was not grossly involving the orifice. TUR of the bladder mass and bladder barbotage were obtained.








Clinical Summary:

A 57-year-old male patient presented with a paratesticular mass consisted of 2 smaller nodules, which were initially resected. The larger nodule was located above the head of the epididymis and measured 1.5 cm in diameter; the adjacent smaller nodule measured 0.5 cm in diameter and originated from tunica vaginalis. The patient had a hydrocele for 6 months prior to the resection.

 

A subsequent radical orchiectomy was performed five months after the initial resection, which also included wide resection of the paratesticular soft tissues, scrotum and portion of the inguinal skin. The resected specimen showed only 3 micronodules adherent the tunica vaginalis, measuring up to 1 mm each. The patient had no local recurrence or metastatic disease during a 6 year follow-up.
