[Systemic lupus erythematosus presenting as Stevens-Johnson syndrome].

Stevens-Johnson syndrome and toxic epidermal necrolysis are life-threatening dermatological conditions. Their most common cause is medication. However, in a small proportion of patients these dermatological conditions could be the first presentation of systemic lupus erythematosus. We now describe a 34-year-old patient who presented with manifestations of Stevens-Johnson as a first feature of systemic lupus erythematosus. Systemic lupus erythematosus reveled by Stevens-Johnson syndrome has been infrequently reviewed in the previous literature. This diagnosis should be considered when cutaneous adverse drug reactions occur without clear drug causality.
