Proposal of the new name “eruptive papular collageno‐elastopathy” to unify the two indistinguishable entities, eruptive collagenoma and papular elastorrhexis

cases, systemic corticosteroids. Corticosteroids have adverse effects, such as immunosuppression and retardation of re-epithelialization, and consequently there are concerns over their use. High-dose corticosteroids should be used with caution in patients suspected of infection-induced SJS, such as our patient. Many studies of IVIG for SJS and TEN have reported an arrest of disease progression and a reduction in the time to skin healing particularly with doses totaling more than 2 g/kg. Although the mechanisms by which IVIG counteracts SJS and TEN are not fully understood, immunomodulating effects are suspected. Therefore, high-dose IVIG would be considered as one of therapeutic options for SJS and TEN, and especially for infection-induced SJS.
