A 31 year old man is referred to the emergency dermatology clinic with a severe flare of his longstanding psoriasis

A 31 year old man is referred to the emergency dermatology clinic with a severe flare of his longstanding psoriasis which had previously been well-controlled with topical therapy for a number of years. After taking a history, you note that he has recently been made redundant, so he has moved back to the UK from Spain and is struggling with low mood and anxiety. His GP has prescribed him two new medications and he has also bought a medication online, which was recommended to him by a friend. He has been drinking 30 units of alcohol per week for the last fifteen years. On examination, he is erythrodermic with well-demarcated, thick, scaly plaques, which are intensely pruritic.
