This link will get you information about how to send slides to Johns Hopkins for a second opinion. http://pathology.jhu.edu/department/services/consults/urologic.cfm Their phone numbers are also listed and the staff is very helpful. I have in the past requested that Dr. Epstein review my slides and sometimes another Dr. will do it. I have also used Bostwick Laboratories. Dr. David Bostwick is also a recognized expert in reading slides from prostate biopsies. Even if another doctor reviews the slides, I have been assured that Dr. Bostwick then reviews their work. They also provide, in my opinion, the most comprehensive and easy to understand report of their findings. The link to their page regarding consultations is https://www.bostwicklaboratories.com/HOME/services/consultations.aspx Their staff is exceptionally helpful and phone numbers are available on other pages of their web site. I'm going for another biopsy soon and although my urologist's practice has a laboratory, I will be sending the slides to Bostwick for a second opinion. Good luck.
