“…To our knowledge, this is the first report of AGEP caused by betamethasone sodium phosphate. To date, 6 cases of AGEP due to systemic corticosteroids have been described (Table S1): in 4 patients due to corticosteroids belonging to Group A and Cluster 1, in one patient to Group C and Cluster 3, and in one patient to deflazacort, which is not included in any group or cluster because of its 16α‐17α‐2 methyloxazolinic ring .
