Abstract
Toxic epidermal necrolysis (TEN) is a rare and low incidence rate disease characterized by pirfenidone-induced skin damage. Pirfenidone is a new anti-fibrotic and anti-inflammatory drug that can alleviate the deterioration of lung function in patients with COVID-19-induced pneumonia and prolong the progression-free survival period. However, side effects of pirfenidone have drawn widespread attention, which include gastrointestinal symptoms, liver damage, skin photosensitivity, and rash. So far, many cases caused by pirfenidone have been reported. As far as we know, cases of TEN induced by pirfenidone have rarely been reported. This article presents cases of TEN induced by pirfenidone, so that clinicians can be aware of the possibility of TEN when using pirfenidone, and how to use inflammation-relevant indicators for evaluating the severity and risk of death of TEN, which has potential clinical value.
期刊介绍：
Clinical, Cosmetic and Investigational Dermatology is an international, peer-reviewed, open access journal that focuses on the latest clinical and experimental research in all aspects of skin disease and cosmetic interventions. Normal and pathological processes in skin development and aging, their modification and treatment, as well as basic research into histology of dermal and dermal structures that provide clinical insights and potential treatment options are key topics for the journal.
Patient satisfaction, preference, quality of life, compliance, persistence and their role in developing new management options to optimize outcomes for target conditions constitute major areas of interest.
The journal is characterized by the rapid reporting of clinical studies, reviews and original research in skin research and skin care.
All areas of dermatology will be covered; contributions will be welcomed from all clinicians and basic science researchers globally.
