Lidia Rudnicka

Lidia Rudnicka was born on February 19, 1960, in Chicago, Illinois. She is a prominent Polish-American dermatologist. Rudnicka graduated from Warsaw Medical School in 1986, having also studied in Bonn and Cologne. She earned her PhD in medical sciences in 1990 and a habilitation degree in 1994. Her early academic career included working as an Assistant Lecturer and Assistant Professor in the Department of Dermatology, Warsaw Medical School, from 1987 to 1998. During this period, from 1990 to 1993, she also worked with American and European institutions, including the Food and Drug Administration (USA), the University of Liège (Belgium), and Thomas Jefferson University in Philadelphia (USA).

Rudnicka’s professional career began in 1986 at the Department of Immunopathology of the National Institute of Hygiene. She became the chairman of the Department of Dermatology CSK MSWiA in Warsaw, Poland, from 1998 to 2014. In 2001, she became a Full Professor in medical sciences. Since 2008, she has been a professor at the Faculty of Health Sciences in the Medical University of Warsaw, and in 2014, she was appointed chairman of its Department of Dermatology. Her research has significantly advanced the understanding and diagnosis of various skin conditions. She co-authored over 200 articles and book chapters on topics such as autoimmune skin diseases, biological therapies, videodermoscopy, trichoscopy, epidemiology of skin diseases, and medical institution management. She is also recognized for her work in sclerederma research, including her hypothesis linking the etiology of systemic sclerosis to a mutation in the topoisomerase I gene. She was among the first to apply in vivo confocal laser scanning microscopy in hair diagnostics, highlighting its potential in evaluating hair shaft diseases.

A key achievement involved her pioneering work in hair and scalp dermoscopy, where she coined the term “trichoscopy.” Her studies demonstrated that trichoscopy could replace traditional microscopic evaluation for diagnosing genetic hair shaft abnormalities. In 2005, alongside Malgorzata Olszewska, she used videodermatoscopy to assess disease severity and monitor treatment effects in androgenic alopecia. She is a co-author of the first Atlas of Trichoscopy, which has been translated into multiple languages. Rudnicka has also been active in public health, organizing the Polish nationwide “Stop-Melanoma” campaign, initiated in 2004, to promote melanoma prevention and early detection.
