A 46-year-old female smoker is seen by her GP as her skin has flared up

A 46-year-old female smoker is seen by her GP as her skin has flared up. She describes a rash on her arms, shins and hairline that is not particularly itchy, but is flaky and scaly. She is finding it increasingly embarrassing. On examination, she has wide-spread, well-demarcated, red plaques with white scaling. On her arms this extends from her wrists to her elbows. She is also noted to have some dry areas on her hands and yellow irregular discolouration of her nails.
