[Patient with pemphigus vulgaris complicated with dysfunctional uterine bleeding upon glucocorticoid usage: a case report].

Pemphigus is a severe chronic autoimmune mucocutaneous bullous disease. Glucocorticoids are considered as the first line of treatment for this disease. Dysfunctional uterine bleeding is also observed as a result of hypothalamic-pituitary-ovary axis dysfunction. This study reported one female patient with pemphigus vulgaris complicated with dysfunctional uterine bleeding upon systemic glucocorticoid usage. Before this disease was diagnosed, the patient experienced normal menstruation. The mechanism of dysfunctional uterine bleeding triggered by glucocorticoids is elucidated on the basis of case studies and literature review.
