Abstract
Psoriasis is a chronic, immune mediated, systemic inflammatory skin disease with a reported prevalence of 0.6%-4.8% in the general population. Bipolar disorder (BP) is a severe episodic psychiatric disorder that ranks as the fourth leading cause of disability. Recent evidence suggests that genetic and immunological factors play a significant role in the development of both disorders. Studies have also shown a higher association of psychiatric disorders among patients with psoriasis. Moreover, several autoimmune comorbidities have been reported in association with BP. Here, we describe a young woman with BP who developed psoriasis after 1 year of developing BP and showed exacerbations in psoriasis lesions with each manic episode. We also highlight the safe and efficacious use of apremilast for psoriatic lesions in the woman.
