12 Contact dermatitis Acute, relapsing/intermittent or chronic presentation Irregular, variable, unilateral or symmetrical dermatitis Sharp border if contact irritant dermatitis Patch tests positive if contact allergy

13 The face is not a common site for psoriasis. It occasionally presents with well demarcated plaques. A more frequent finding is similar to tha seen in Treatment Emollients and gentle non soap cleansers Vitamin D analogues such as silkis ointment in combination with hydrocortisone Tacrolimus ( 0.1%Protopic ) ointment but unlicenced Psoriasis seborrhoeic dermatitis.
