Clinical assessment included detailed medication reconciliation, infectious evaluation, markers of inflammation, response to glucocorticoids, and recurrence upon re\u2010exposure.

Within days of the second dose, she experienced a more extensive recurrence involving the hands, thighs, and right calf, which resolved after a glucocorticoid taper. Infectious evaluation was negative, markers of inflammation were normal, and medication reconciliation did not identify alternative pharmacologic triggers. Romosozumab was discontinued, and no recurrence occurred during follow\u2010up before transition to denosumab.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case supports a probable association between romosozumab and recurrent EN.
