Etiology
- hypersensitivity (most likely)
- possibly immunologic
- drugs & infection most likely triggers
- pharmaceutical agents (~70-80%)[2][10][12]
- antibiotics 32%[13]
- anticonvulsants (19%)[12]
- NSAIDs (12%)[12]
- meloxicam, piroxicam, tenoxicam
- diclofenac, indomethacin, ionazolac, etodolac, aceclofenac, sulindac, ketorolac
- others
- allopurinol (11%)[12], sertraline, pantoprozole, sulfasalazine
- carbonic anhydrase inhibitors used in ophthalmic agents to treat glaucoma
- influenza vaccine[2] (temporal association, case report, MKSAP20)
- see pharmaceutical agents causing SCARs
- infections (26%)[2]
Epidemiology
- most common in young adults
- male:female ratio 2:1
Pathology
- acute epidermal necrosis (full thickness)
- involvement of mucous membranes
- potentially fatal due to secondary infection, transcutaneous fluid loss, respiratory complications
* histopathology image[6]
Genetics
- drug-induced SJS (carbamazepine, phenytoin, allopurinol) linked to HLA-B*1502 in Han Chinese (Asians, South Asian Indians)
Clinical manifestations
- prodrome of fever, malaise, arthralgia, headache, respiratory symptoms, vomiting &/or diarrhea 1-14 days before appearance of skin lesions (generally in 1st week)[2]
- skin & mucous membrane manifestations
- diffuse pruritus or burning may occur in the prodromal phase
- early lesions are pink, edematous papules
- these then evolve into dull, red macules with central cyanosis or into vesicles (atypical 'target lesions')
- lesions can coalesce & progress to flaccid bullae with sloughing
- positive Nikolsky sign[14]
- lesions are most prominent on extremities, palms & soles
- erosive lesions may occur on mucous membranes
- oral mucosa
- conjunctiva: eye foreign body sensation, ocular gritty sensation
- genitourinary: dysuria
- mucosa alone may be affected
- hemorrhagic crusting of oral mucosa is characteristic[2]
- blepharitis: eye foreign body sensation - ocular gritty sensation
- systemic manifestations
- time course: 4-6 weeks
Laboratory
- blood cultures
- complete blood count (CBC)
- serum electrolytes, serum urea nitrogen, serum creatinine
- liver function tests
- erythrocyte sedimentation rate may be elevated
- urinalysis
- skin biopsy if diagnosis uncertain
- full-thickness epidermal necrosis[9]
- do not screen for SJS or TEN with HLA-B*1502 & HLA-B*5801[2]
Complications
- epidermal necrosis resulting in infection, sepsis
- mortality is 1-5% (5-13%[2])
- long-term sequella SJS/TEN[11]
- post-inflammatory dsypigmentation: hyperpigmentation, hypopigmentation, or a combination
- hypertrophic or keloidal scars
- nail changes: onycholysis or onychomadesis, onychorrhexis, onychoschizia, koilonychia, erythronychia, oil-drop sign
- nail loss may be permanent (20%)
- hair changes: telogen effluvium is common
- eruptive nevi & atypical nevi
- other cutaneous manifestations: pruritus, hyperhidrosis, photosensitivity, heterotopic ossification, ectopic sebaceous glands
Differential diagnosis
- erythema multiforme
- target lesions (only distinguishing feature provided in MKSAP20)[2]
- DRESS syndrome (lymphadenopathy)
- often delayed onset 2-6 weeks
- morbilliform exanthem, facial edema & redness
- generalized exanthematous pustulosis
- erythroderma
- diffuse erythema covering 80% to 90% body surface area
- pruritus, peripheral edema, erosions, scaling, & lymphadenopathy
- toxic epidermal necrolysis (TEN) is a severe form of SJS
- Stevens-Johnson syndrome (SJS) & toxic epidermal necrolysis (TEN) represent a continuum of a single disorder
- in SJS, skin detachment involves < 10% of body area
- in TEN, skin detachment involves > 30% of body area
- in SJS-TEN overlap syndrome, 10-30% of body area involved
Management
- hospitalize; admit to intensive care unit (burn unit)
- identify & eliminate triggering agent
- mild disease (erythema multiforme minor)
- outpatient treatment with topical steroids
- dermatology follow-up
- severe disease (Stevens-Johnson syndrome)
- a short course of high intensity glucocorticoid treatment may be of benefit
- intravenous immune globulin controversial[2]
- cyclosporine has been used[12]
- treat secondary infections
- no role for prophylactic antibiotics[2]
- ophthalmology consult for eye involvement
- prognosis: mortality 10% generally due to infection

Additional terms
