Sodium nitroprusside (SNP) is one of the most widely used parenteral antihypertensive agents in severe hypertension management. Toxic epidermal necrolysis (TEN) is a rare, mostly drug-induced, severe muco-cutoneous reaction with various complications and high mortality. A fifteen years old girl who is on hemodialysis for chronic renal insufficiency and was hospitalized for emergency management of hypertension, developed a diffuse maculopapular rash within minutes after SNP infusion. In 72 hours, approximately 40% of the body surface was involved with skin detachment indicating epidermal necrolysis and a skin biopsy confirmed the diagnosis of TEN. To the best of our knowledge there is no report of an association of SNP and TEN in the English literature and the clinical data exemplifying consequent IgE and non-IgE mediated hypersensitivity reactions are scanty. With this report we wanted to present a rare complication of SNP infusion indicating another rare occurrence of sequential IgE and non-IgE mediated hypersensitivity reactions.

Fixed drug eruption (FDE) is a type of drug-induced skin inflammation characterized by the recurrence of lesions in the same region following repeated exposure to the causative drug. FDE typically presents as localized spots or plaques without systemic symptoms; however, it can manifest in other forms, such as blisters and papules. In FDE, effector memory CD8-positive T cells that remain dormant in the basal layer after a previous inflammation are reactivated upon re-exposure to the causative drug, leading to the development of erythema at the same sites.

Background: Immune checkpoint inhibitors (ICIs) have been widely applicated for the treatment of patients with advanced esophageal cancer. Skin-related adverse reactions are frequent with ICIs, with toxic epidermal necrolysis (TEN) being a severe and potentially life-threatening cutaneous reaction.
Case Presentation: We present a case of a 70-year-old male with locally advanced esophageal cancer who developed severe toxic epidermal necrolysis (TEN) after 18 days of tislelizumab combined with chemotherapy.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe mucocutaneous disorders characterized by extensive tissue necrosis; they are often accompanied by severe ocular complications (SOC). The regulatory role of microRNAs (miRNAs) in modulating immune responses in SJS/TEN is not fully understood, particularly in relation to chronic SOC. We explored the expression profiles of specific miRNAs and their potential impact on the regulation of key innate immune genes in patients with SJS/TEN with SOC.

Background: Epidermal necrolysis (EN) is a rare and severe condition, characterized by a diffuse skin and mucosal detachment and mainly induced by drugs. Literature is scarce regarding the rate of recurrences and culprit drug re-exposure.
Objectives: To assess the rate of EN recurrences as well as high notoriety drugs re-exposures in patients with EN.
