Erythema iris	Is a	A limited form of Stevens-Johnson syndrome/toxic epidermal necrolysis spectrum characterised by destruction and detachment of the skin epithelium, involving less than 10% of the body surface area, and mucous membranes. Onset usually occurs 4-28 days after administration of the causal medication and is most frequently associated with anticonvulsants, antibacterial sulfonamides, allopurinol, nevirapine, and oxicams (non-steroidal anti-inflammatory drugs), but many other medications have also been implicated. The disease is not induced by medication in 15% of cases. Histology is characterised by an epidermal necrolysis. Multiple disabling long-term sequelae (especially cutaneous, ocular and psychological) are frequent.	false	Inferred relationship	Some

Erythema iris	Due to	A pathological immune process generally directed towards a foreign antigen, which results in tissue injury, which is usually transient. It is the realization of the allergic disposition. It is most often applied to type I hypersensitivity but other hypersensitivity types especially type IV (e.g. allergic contact dermatitis) may be involved.	false	Inferred relationship	Some
