BACKGROUND Adverse drug reactions are harmful and involuntary responses to drugs that occur at doses normally used for a given condition. Among them are Stevens-Johnson syndrome and toxic epidermal necrolysis, both rare and potentially fatal conditions. OBJECTIVES To analyze the epidemiological and clinical characteristics related to patients diagnosed with Stevens-Johnson syndrome and toxic ...

COVID-19 is a global pandemic caused by novel zoonotic RNA virus named SARS-CoV-2. Various cutaneous manifestations associated with have been described, including urticarial rash, confluent erythematous papulovesicular exanthem, chilblain-like acral pattern, livedo reticularis, and purpuric vasculitis pattern. Here, we are presenting case of 45-year-old male mucocutaneous features Stevens-Johns...

Stevens Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, life-threatening cutaneous severe adverse reactions (SCAR) most frequently induced by a drug hypersensitivity. The clinical manifestations seem to be related either to a particular group of drugs, such as antibacterial sulfonamides, anticonvulsant agents, allopurinol, non-steroidal anti-inflammatory drugs (NSAIDs), am...

Vandetanib is a once-daily oral anticancer drug that selectively inhibits key signaling pathways in cancer by targeting vascular endothelial growth factor receptors, epidermal growth factor receptors tyrosine kinase, and rearranged during transfection-dependent tumor cell proliferation and survival. The most frequently reported adverse events attributed to vandetanib include diarrhea, elevated ...

The authors studied the histopathologic, ultrastructural, and immunopathologic characteristics of conjunctiva from patients with Stevens-Johnson syndrome (SJS). A small subset of SJS patients with recurrent conjunctival inflammation unassociated with external factors such as lid margin keratinization, sicca syndrome, trichiasis, or entropion was identified. The ultrastructural and immunopatholo...

Stevens-Johnson syndrome (SJS) has been described in the literature as a combination of erythematous blistering skin lesions covering <10% of body surface area and ≥1 mucous membrane erosion.1 SJS is usually triggered by a medication or infection. Infectious causes are more common in children, most notably herpes simplex virus (HSV) and Mycoplasma pneumoniae. Mucous membrane erosions without si...

The term toxic epidermal necrolysis (TEN) was introduced in 1956 by Lyell to describe four patients with a syndrome featured by extensive epidermal detachment with mucous membrane involvement, leaving the skin surface looking scalded. Necrolysis denotes necrosis and full thickness detachment of the epidermis. Toxic means severe constitutional symptoms and complications. Stevens-Johnson syndrome...

Fuchs syndrome is a milder form of the Stevens-Johnson syndrome (SJS) spectrum with only mucosal involvement which can be triggered by Mycoplasma pneumonia (MP) infection. Treatment should be directed toward supportive care including ocular and mucous membrane care, fluids and nutritional support, and pain control. In addition, antibiotic and immunomodulatory treatments are discussed for this e...

Stevens-Johnson syndrome mostly involves the skin and mucous membranes. The diagnosis is made when the characteristic rash appears 1 to 3 weeks after exposure to a known stimulus and cannot be explained by some other diagnosis. A 62-year-old woman was admitted for evaluation of toxo-allergic dermatitis and collagenosis. Ten days prior to admission she was taking a course of azithromycin for upp...
