In 1798, Robert Willan published the founding textbook of British dermatology. In adopting the elementary lesions principle previously described by Josef Plenck and improving the nomenclature of the skin diseases, Willan established a method for the diagnosis and a doctrine for the nosology of the cutaneous diseases. Introduced into France by Biett in the 1810s, the Willanist method, which allowed diagnosis on the basis of objective criteria, was adopted by the majority of the dermatological community. However, as a doctrine, Willanism, the use of elementary lesions as a framework for classifying diseases, became the subject of lasting debate. In fact, apart from a few, most leading French dermatologists did not accept Willan's doctrine and preferred classifications according to systems which were supposed to reflect the best understanding of the cutaneous diseases: physiological, aetiological and pathological. Willanism is still used by every dermatologist as a method for recognizing skin diseases. It constitutes a firm link to the founding period of modern dermatology and remains a bastion against uncertain hypotheses.
Ritual circumcisions can be classified into types according to the circumstances in which they are performed. Spiritual circumstances which express a community identity, usually religious and surrounded by a complex significance related to numerous myths, especially biblical and African. Non-religious circumcisions, particularly well illustrated by the USA model, comprise, apart from controversial medical and scientific reasons, a real social dimension and also reflect a desire for community membership. Regardless of the circumstances, surgeons may sometimes be asked to perform circumcision and should be aware of the significance of this procedure.

Prior to the first use of penicillin against syphilis in 1943, mercury had a prominent position in the medical practice despite a tremendous toxicity and a questionable efficiency. In fact, during 450 years mercury remained the guarantee of efficacy. The modalities of use increased, the durations of treatment lengthened without any evidence of a worsening morbidity. This history of an exceptional duration seems to be a good example of the weight of tradition or habit in the medical practice, of the importance of the constraints supported by the patients, of the necessity and the difficulties to evaluate the treatments without error.
Created in 1865, by Alphonse Devergie, physician and head of one of the medical departments in Saint-Louis hospital, the first iconographic collection of the museum was made by water-colours, photographs from the atlas by Hardy and Montméja. Financially supported by the assistance Publique in Paris, thanks to the interest of its manager, Armand Husson, the museum was then enriched by the wax moulages produced by Jules Baretta, from 1867 onwards. Due to the development of the collection, the erection of a specific building was soon regarded as a necessity. The attention given to the project, by Bourneville, City Councellor in Paris, made it possible. First managed by Charles Lailler, physician in Saint-Louis, the museum was definitely located, with the medical library (later called Bibliothèque Henri Feulard), in an independent building, inaugurated August 5th 1889 on the opening of the first International Congress of Dermatology and Syphilology. This new museum, still existing in its original condition, was a part of the restoration of the international influence of the French school of dermatology.
