Patient case (clinical description): A 2-year-old boy is brought to the office by his parents due to a rash that started 1 week ago.  A similar red, itchy rash on the cheeks, trunk, and arms has occurred intermittently since infancy.  The patient has had a few upper respiratory infections but no major illnesses.  Vaccinations are up to date, and he takes no medications. He is on a balanced diet, and he is healthy in appearance.  Vital signs and milestone examination are within normal limits.  Similar findings are observed on the cheeks and proximal upper extremities.  The diaper area is clear, and no mucosal lesions are present.

Patient's own account: I just brought my two-year-old son to the doctor's office because he had a rash for like one week. His rash was on the cheeks, the trunk, and his arms. He already had this before, and it keeps coming back from time to time to time. In the past, he had some respiratory infections but he has never been this sick. His vaccinations are up to date, and he doesn't take any medication. He's healthy with a nice diet. The doctor told me his vitals and milestone examinations were normal. The doctor also said there was a rash around the cheek and the upper part of his arms. The diaper area is okay, and there are no lesions.

Clinical trial: A Phase 1/2 Study of E6005 in Pediatric Subjects With Atopic Dermatitis

Eligibility criteria:
Inclusion Criteria

          1. Pediatric out-patients diagnosed with AD aged 2 to 15 years at the time of written
             informed consent. Diagnosis for AD should be made in accordance with the "Guidelines
             for Management of Atopic Dermatitis" by the Japanese Dermatological Association.

             application of study drug is possible, except the skin of face/head and non-dermal
             areas such as mucosa

          3. Evaluable skin lesions appearing at baseline. "Evaluable skin lesion" means rash area
             of 25 to 100 cm2 in the trunk or extremities, in which at least one of dermal symptoms
             (erythema, exudate/eschar, excoriation or lichenification) must be moderate in
             severity.

          4. Continuous use of an appropriate moisturizer for at least 14 days before baseline

          5. Females of child-bearing potential must be negative for pregnancy test at baseline and

             without a sufficient washout period, except hydrocortisone butyrate preparations used

          7. Difficulty in venous access for blood collection

          8. Any past history or present illness of malignant tumor, lymphoma, leukemia or
