These terms have evolved from the originally described lichenoid tissue reaction. These lesions are the basis for an important group of skin diseases in animals and people where cytotoxic T-cell-mediated epidermal damage is a major pathomechanism. Yet, for largely historical reasons these commonly used morphological diagnostic terms do not reflect the essential nature of the lesion. An emphasis on subsidiary lesions, such as the presence of a lichenoid band, and definitions based on anatomical features, such as location at the dermo-epidermal location, may cause confusion and even misdiagnosis. This review covers historical aspects of the terminology, including the origin of terms such as \u201clichenoid.\u201d The types of cell death involved and the histopathologic lesions are described. Etiopathogenesis is discussed in terms of aberrations of immune\/inflammatory mechanisms focusing on cutaneous lupus erythematosus, erythema multiforme, and Stevens-Johnson syndrome\/toxic epidermal necrolysis. Mechanisms have most extensively been studied in humans and laboratory animals and the discussion is centered on these species. As interface dermatitis is firmly entrenched in dermatological parlance, rather than using \u201ccytotoxic\u201d as its substitute, the terminologies \u201cinterface cytotoxic dermatitis\u201d and \u201cpanepidermal cytotoxic dermatitis\u201d are recommended, based on location and extent of epithelium affected.<\/jats:p>","DOI":"10.1177\/03009858231195080","type":"journal-article","created":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T04:34:32Z","timestamp":1693456472000},"page":"770-782","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Cytotoxic
