Association of severe Raynaud’s phenomenon with psoriasis – a rare manifestation

Raynaud’s phenomenon defines the clinical consequence of recurrent vasospasm of the small arteries, arterioles, and arteriovenous shunts of the fingers and toes provoked by cold and emotional stress. Other acral parts, such as the nose, lips, ears, and penis, may also be affected. Despite several similarities between the pathogenesis of psoriasis and autoimmune diseases, it was surprising to find low frequencies of disease associations. We present a case of a 19-year-old boy with familial chronic plaque psoriasis who developed severe Raynaud’s syndrome with penile involvement.
