He then returned to Japan temporarily for a legal matter and was treated with olopatadine hydrochloride, an antihistamine drug, and betamethasone butyrate propionate ointment at a dermatology clinic. Since lesions were not improved despite the treatments described above, the patient was introduced to our department.

We suspected contact dermatitis to plants, paint, or resin of bench based on morphology, and those lesions improved by administration of prednisolone, 10 mg for 3 days, and betamethasone butyrate propionate ointment for 7 days.
