Facial Irritant Contact Dermatitis Caused by Pyraclostrobin

Contact dermatitis and facial contact dermatitis caused by pesticides are not uncommon in China. However, clinically, due to the wide variety of pesticides, they mainly appear in the form of case reports. We reported a 70-year-old male patient developed facial irritant contact dermatitis (ICD) due to pyraclostrobin which was sprayed on his face. Initially, he felt facial burning and tingling, and localized erythematous-edematous and scaly rash appeared on his face as well as front hairline scalp. During the outpatient visit, the main symptoms were a facial burning sensation, itching, and tingling. The patient’s facial lesions improved after treatment. To better protect the skin of agricultural workers, preventive measures should be undertaken, such as personal protective equipment, gas masks, protective clothing and goggles, which are indispensable for manual pesticide spraying. Pyraclostrobin diluted according to the instructions is a potential source of ICD. Agricultural workers should undertake preventive measures during manual pesticide spraying. Safety education and publicity are particularly important. We need dermatologists to spread knowledge and agricultural workers to develop the right protective habits.
