Atopic dermatitis:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
Typically, the patient has a history of atopy, such as asthma, hay fever, or urticaria; his family may have a similar history. Laboratory tests reveal eosinophilia and elevated serum IgE levels. A skin biopsy may be performed, but it isn’t always required to make the diagnosis.

Dermatitis:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
A family history of allergy and chronic inflammation suggests atopic dermatitis. Typical distribution of skin lesions rules out other inflammatory skin lesions, such as diaper rash (lesions are confined to the diapered area), seborrheic dermatitis (no pigmentation changes, or lichenification occurs in chronic lesions), and chronic contact dermatitis (lesions affect hands and forearms, sparing antecubital and popliteal areas). Serum IgE levels are usually elevated.

Wilson's disease:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
Several tests suggest Wilson’s disease:
❑ Serum ceruloplasmin: less than 20 mg/dl
❑ Serum copper: less than 80 mcg/dl
❑ Urine copper: more than 100 mcg/24 hours (may be as high as 1,000 mcg)
❑ Liver biopsy: excessive copper deposits (250 mcg/g dry weight), tissue changes indicative of chronic active hepatitis, fatty liver, or cirrhosis.
CONFIRMING DIAGNOSIS Revelation of Kayser-Fleischer rings during slit-lamp ophthalmic examination confirms the diagnosis. However, rings are present only when the disease has progressed beyond the liver.

Erythema [Erythroderma]:
History and physical examination
(Professional Guide to Signs & Symptoms (Fifth Edition))
If erythema isn’t associated with anaphylaxis, obtain a detailed health history. (See Differential diagnosis: Erythema, pages 310 and 311.) Find out how long the patient has had the erythema and where it first began. Has he had any associated pain or itching? Has he recently had a fever, an upper respiratory tract infection, or joint pain? Does he have a history of skin disease or other illness? Does he or anyone in his family have allergies, asthma, or eczema? Find out if he has been exposed to someone who has had a similar rash or who is now ill. Did he have a recent fall or injury in the erythematous area?
Obtain a complete drug history, including recent immunizations. Ask about food intake and exposure to chemicals.
Begin the physical examination by assessing the extent, distribution, and intensity of erythema. Look for edema and other skin lesions, such as urticaria, scales, papules, and purpura. Examine the affected area for warmth, and gently palpate it to check for tenderness or crepitus.
Cultural Cue: Dark-skinned patients may have difficulty recognizing erythema; as a result, they may present with associated diseases in a more advanced state.

A family history of atopic disorders is helpful in the diagnosis of atopic dermatitis.
Typical distribution of skin lesions and course rule out other inflammatory skin lesions, such as diaper rash (lesions confined to the diapered area), seborrheic dermatitis, and chronic contact dermatitis (lesions affect hands and forearms, sparing antecubital and popliteal areas).
