Louis-Anne-Jean Brocq

Who was Louis-Anne-Jean Brocq?

Louis-Anne-Jean Brocq was a French dermatologist born in Laroque-Timbaut, a village in the department of Lot-et-Garonne.

He practiced medicine in Paris at the Hospice la Rochefoucauld, the Hôpital Broca, and from 1906 to 1921, the Hôpital Saint-Louis. As a young physician he studied and worked with Jean Alfred Fournier, Jean Baptiste Emile Vidal and Ernest Henri Besnier.

Brocq provided early, comprehensive descriptions of numerous skin disorders, including keratosis pilaris, parapsoriasis and a form of dermatitis called "Duhring-Brocq disease". Other eponymous skin diseases named after him are "Brocq's pseudopelade", a condition involving progressive scarring of the scalp, and "Brocq-Pautrier angiolupoid", a specific type of sarcoidosis of the skin named in conjunction with Dr. Lucien-Marie Pautrier. Brocq is also credited for developing a tar solution used for the treatment of psoriasis.

In 1900, Brocq published the first French encyclopedia of dermatology; a four-volume treatise named Pratique Dermatologigue.
