Skin rash/Psoriasis: Thank you for your question. Dandruff and a lymph node may be caused by many things. There are forms of inflammatory conditions of the skin (like psoriasis) that could cause a rash as well as responses to external sources such allergies to topical agents or otherwise. Having an examination performed by a qualified medical practitioner would be helpful in diagnosis and treatment.
