H15 Inflammation Of The Hair Follicle: Multiple Eponyms

The document traces the historical evolution of the terminology and understanding of Hidradenitis suppurativa (HS), a chronic inflammatory condition of the hair follicles and sweat glands. Initially described by Velpeau in 1833 as a tuberiform phlegmon, it underwent several name changes, reflecting evolving insights into its pathogenesis. Verneuil, in the mid-19th century, recognized it as a sweat gland disorder, coining the term 'hidradenitis suppurativa.' Subsequent terms like 'acnitis' and 'folliclis' were introduced but later rejected. Pillsbury's 'follicular occlusion triad' in 1956 and Plewig and Kligman's 'acne tetrad' in 1975 further refined its classification. Despite suggestions to rename it 'acne inversa' based on histopathological similarities, HS remains the accepted term, highlighting ongoing debates and the need for further research.
