Psoriasis and psoriatic arthritis are chronic inflammatory diseases of the skin and joints, but the relationship between them has not been fully understood. Since the delay of treatment for psoriatic arthritis can result in the severe deformities, it is important to identify the pathological triggers of the arthritis. On the other hand, many reports suggest that the changes of immune balance during pre/postpartum period are associated with the state of autoimmune diseases. Here, we report a female case with psoriasis whose arthritis may be triggered by the delivery. Our report suggests that immune tolerance may diminish in the postpartum period, which may alter the susceptibility to arthritis. Female patients should be followed-up carefully during postpartum period against the development of arthritis.
