Guess What!
The diagnostic case of the ESTP

In this interactive ESTP section, which is meant as a common approach for continuing education, two interesting cases from the field of toxicologic pathology will be presented each year, waiting for your active participation! After posting, the respective case will be open for approximately six months for providing YOUR preferred diagnosis, but also your suggestions, questions or comments are highly welcome. Though we know how limited your time schedule is by your daily work, we encourage everyone of our community to send in a diagnosis electronically, either anonymously or by submitting his/her name and e-mail address.

 The current case:

  closing:   05-Sep-2024

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.

We thank you for your participation in this Magical Mystery ToxPath Tour and are looking forward to receiving your diagnoses.

Your "Guess What! Team"
