Stevens–Johnson syndrome induced by tonic water.

The patient in this manuscript has given written informed consent to publication of his case details. PTs on unaffected skin were negative in all seven cases tested, while PTs on affected skin were 52.6% (10/19) positive. Repeated intake of tonic water can worsen the extent of eruptions but they rarely progress to severe eruptions such as toxic epidermal necrolysis (TEN) and generalized bullous fixed eruption (GBFE).4,5 Stevens-Johnson syndrome is a life-threatening cutaneous hypersensitivity reaction, typically to a medication.
