Abstract

Introduction

Paederus dermatitis (PD) is an irritant contact dermatitis (ICD) triggered by a beetle from the genus Paederus, which is a part of Staphylinidae family. PD, also referred to as dermatitis linearis, is a condition caused by the toxin released from the beetles. Rarely but when this insect bites or stings, the fluid released from this beetle usually contains paederine. It is a potent toxin found inside these insects’ body fluids. It can lead from erythematous to vesicular lesions, blisters, and a burning/pain sensation on the exposed areas of the body.

Case Presentation

In this setting, we reported two cases of 35-year-old and 30-year-old Cambodian males who presented with an abrupt burning sensation, itchy oozing rash, streaky linear lesion, and kissing lesions. A short course of oral corticosteroids, topical antibiotics, steroid cream, and bar soap were prescribed to treat symptoms. The prognosis is favorable and the recovery is self-limiting within 7-10 days.

Conclusion

Even though PD has a small outbreak, it should not be overlooked especially during the rainy season. Healthcare personnel should not only focus on the disease but also need to be aware of the patient’s surrounding environment. Although the disease is self-limiting, it can cause tremendous discomfort to patients. Education and prevention should be put out to raise awareness of this condition.
