Allergic photocontact dermatitis developed in a patient to a commercial sunscreen preparation containing para-aminobenzoic acid (PABA) in an alcohol base. Photopatch testing showed photosensitivity to PABA. Sensitization could only be detected when PABA was tested in an alcohol vehicle; a photopatch test to PABA in petrolatum was negative.
一名患者对一种含对氨基苯甲酸（PABA）的酒精基质商用防晒霜制剂发生了变应性光接触性皮炎。光斑贴试验显示对PABA光敏。仅当PABA在酒精载体中进行检测时才能检测到致敏；对凡士林基质中的PABA进行的光斑贴试验为阴性。
