Pierre Louis Alphée Cazenave (1795 – 1877) was a French dermatologist who practiced medicine at the Hôpital Saint-Louis in Paris.
In 1823 he was appointed interne to the hospitals of Paris, and in 1835 became professor agrégé to the medical faculty. Cazenave was a student of Laurent-Théodore Biett, a physician who introduced into France an anatomical approach for analysis of skin disorders. This analytical method was first developed by two English physicians; Robert Willan and Thomas Bateman.
In 1828 with Henri Édouard Schedel, he published a work based on Biett's lectures and observations titled Abregé pratique des maladies de la peau. This compilation was to become a highly influential text regarding dermatology in the mid-19th century.
From 1844 until 1852, Cazenave was editor of Annales des Maladies de la Peau et de la Syphilis, which was a journal dedicated to scientific dermatology.[1]
He is credited with coining the term "lupus erythematosus", which he derived from Biett's symptomatic descriptions of the disease. In 1844 he described pemphigus foliaceus as a special type of pemphigus.
