Remarque: pour de nombreux cas, il n'existe pas de confirmation opératoire ou histologique du diagnostic. Cependant, le choix s'est porté sur des exemples illustratifs où le diagnostic s'impose sur la base de l'anamnèse et de critères diagnostiques reconnus; parfois, il ne s'agit que d'un diagnostic de probabilité élevée mais dont l'intérêt méritait de figurer dans cette liste. L'anonymat des cas présentés ici respecte le secret médical.

Note: diagnoses on this page are often not surgically or histologically proven. However, for most cases diagnosis is unequivocal when considering clinical history and current diagnostic criteria; less often, diagnosis was only highly probable but the case was considered worth to be shown. Image anonymisation is performed to ensure medical secret.
