HPV of the bladder is rare but it does happen and you want to make sure you're at a top notch medical center with a great pathologist as it will mimic blc ..

I would certainly alert them to the fact that you've had HPV.
But having said that don't panic....hopefully you will have a cystoscopy on Monday and a bit more knowledge at that point.
As for CIS the histologic pattern of CIS is characterized by bizarre, abnormal cells in the epithelial layer. The cells appear to be high-grade cancers; thus, they are readily detected in cytology specimens.
The pathologist may have difficulty distinguishing between cellular atypia and CIS. A consultant should review the slides if the pathologist is uncertain or diagnoses atypia. Upon further review, these cases usually prove to be CIS. The distinction is important because CIS requires therapy and atypia can be managed with observation. Finally, some pathologists attempt to grade CIS; however, CIS is not graded. An associated papillary tumor would be graded as low or high grade
My best advise is to make sure you are with a top notch urologist and top medical or cancer center.
