  2. Where on the legs is the rash and where did it start?

    Why: diagnosis may be helped when the rash is in a specific area e.g. typical lower leg rashes include keratits pilaris, erythema nodosum, nummular dermatitis, stress dermatitis, necrobiosis lipoidica; typical rashes on the front of the knees include psoriasis and dermatitis herpetiformis; a typical rash on the back of the knees is atopic dermatitis.

  3. Is the rash on any other part of the body?

    Why: i.e. localized to legs or widespread? - If the rash is widespread, is it distributed centrally, peripherally or both.

  11. Medications?

    Why: some medications may cause sensitivities such as aspirin, morphine and codeine.

  16. Fever?

    Why: may suggest chicken pox, exfoliative dermatitis, severe allergic contact dermatitis (e.g. from a strong allergen such as poison ivy); eczema herpeticum.

  17. Symptoms of atopic dermatitis (eczema)?

    Why: e.g. itchy, red, dry, scaling, cracked skin. The typical distribution changes as the person grows older.

  22. Symptoms of dermatitis herpetiformis?

    Why: e.g. extremely itchy condition with vesicles (fluid filled blisters less than 1 cm in diameter) mainly over the elbows and knees but may also occur on the trunk, buttocks and shoulders. Associated with Celiac disease.

  23. Symptoms of chronic venous insufficiency on lower legs ?

    Why: e.g. leg swelling, darkened skin, inflammation of the skin, possible ulceration on the lower legs - may suggest "varicose eczema" which is characterized by patches of dry scaly skin that overlie leg varicose veins.

  24. Symptoms of erythema nodosum?

Adult females are typically affected. May be associated with sarcoidosis, inflammatory bowel disorders, some medications and some infections.

  25. Symptoms of necrobiosis lipoidica?
