The cosmopolitan beetles of the Paederus genus (potós) cause a severe dermatitis when the insect is crushed against the skin of exposed areas (the cervical region is the most affected). Toxins (pederin and others) from the hemolymph of the insect cause plaques and/or bizarre, linear lesions with erythema, edema, blisters, pustules, crusts and exulcerations. There may be a burning sensation and ...

Outbreaks of Paederus dermatitis have been reported in several Asia-Pacific countries when rove beetles (genus Paederus) are accidentally brushed or crushed on the skin, releasing haemolymph pederin. An investigation was conducted in a school to ascertain the causative agent, establish the case definition, epidemiological characterisation of cases, entomological and environmental survey and dat...

Paederus (Harpopaederus) xui Peng & Li, sp. n. (Sichuan: Micang Shan) is described. Additional records of five Harpaederus species are reported. All of these species are illustrated.

AbstractPaederus dermatitis is an irritant contact dermatitis due to accidental contact by a beetle belonging to the genus paederus. In this study, clinical efficacies of S. ebulus fruit extract solution in patients affected by paederus dermatitis were evaluated. A randomized double-blind, prospective, placebo-controlled clinical trial was performed in 62 patients with clinical symptoms and sin...

BACKGROUND Dermatitis caused by Paederus beetle involves many people around the world, especially Iran. The symptoms include redness, itching and severe irritation. This study evaluated the effectiveness of the Aloevera cream on the treatment of dermatitis caused by Paederus beetles. METHODS Forty male 6-8 weeks BALB/C mice were randomly divided into four groups of 10 mice. After removing the...

Paederus dermatitis, a kind of irritant contact dermatitis by Staphylinid beetle, is more prevalent in Asia-Pacific countries with the attributes of tropical climate. Brushing, pressing, or crushing of the beetle against the skin releases the pederin toxin (pederin) that can produce urticarial, vesicular, and bullous lesions. We conducted a 1-year retrospective study of 84 patients with Paederu...
