Call for Scientific Cooperation

#9 Two separate nodules within the same testis (Oct. 2016)

Dear Friends,

We have recently collected four cases of patients with two separate nodules within the same testis which proved to be of different histologic nature at pathology (three cases had nodules which were tumours of different histology; the remaining case had one nodule which was seminoma while the second was a benign hyaline focal lesion).
If you have similar cases (imaging pictures as well as pathologic proof of the nature of each of the lesions), please contact me

Thanks for your help and ciao,
Lorenzo Derchi

Call #3 Fibrous proliferation of the renal transplant (Dec. 2012)

We have recently met two cases of large fibrous proliferation involving the hilum and pedicle of renal transplants. The patterns were initially suggestive of a lymphoproliferative disorder, but the follow-up show very slow growth while pathology confirmed benignity with massive fibrous proliferation.

If you observed similar cases, please write me: m.claudon(at)

Call #1 Bladder pheochromocytoma (Dec. 2012)

I have recently met a patient with a bladder pheochromocytoma. There are only case reports or small series on this rare conditions, and this new feature of the ESUR website can help to gather many and prepare a meaningful publication.

If you have cases, please write me at: marie-france.bellin(at)
