The microscopy slides of this website are specimens removed from real patients. Every measure has been taken to eliminate the possibility that individual slides and case histories are 'recognized' by patients or third parties. To that end, slight changes in patient's age and other details have sometimes been made, especially in case of rare entities, where the chance of fortuitous recognition might be somewhat higher. Hoever, the clinical information is always very similar to the true clinical data, in order to avoid misinformation that might be relevant to the pathological evaluation of the case.
If you suspect that you have recognized an individual case, chances are very high that you are mistaken, since the numbers of similar cases is always very high, in view of the prevalence of the entities discussed in this site.
