A new Guess What case will follow in the foreseeable future.

After evaluating the survey, we have developed a new concept proposal. This will be implemented for the new case and an announcement will appear on this website shortly.

The recent case: Testis lesion of a 22 months old Wistar rat

After the posting period, the diagnosis and a detailed description will be presented as proposed by the provider of the case including the contributions made by you, the participants.

Previous cases will remain available on the ESTP Web site as a repository so that you have always the opportunity to look them up and to refresh your memory. The partially descriptive diagnoses moreover are adapted for your convenience to the current INHAND term.

In order to maintain the fully interactive nature of this section of the ESTP Web site, it is important that You submit Your “mysterious” and interesting cases to us, no matter whether they represent induced or spontaneous lesions, and regardless of whether or not you are a member of the ESTP. Even if you don't have a definite diagnosis at the time of submission, there might be someone in our community who has the sparkling idea. Please, contact the "Guess What! Team" or look up the suggestions for submitting a case.

Your "Guess What! Team" Susanne Rittinghausen, Matthias Rinke, Dirk Schaudien
