Potassium permanganate use in the management of a wound induced by contact with Paederus : A case report

Pederin is a vesicant toxic amide, found in the hemolymph of the beetle genus, . Physical contact with these insects produces a type of irritant dermatitis with variable clinical symptoms. It has been identified that Pederin (a vesicant toxic amide responsible for the ulcerative lesion) is produced by Gram-negative endosymbiotic bacteria of the genus. The present study describes the case of a patient who had come into contact with the insect sp. and developed an ulcerative lesion. He was first treated with topical steroids, as part of the conventional management, and following no response to treatment, he was treated locally with a 5% potassium permanganate solution, in conjunction with systemic antibiotic therapy, obtaining a good response in the healing process. On the whole, the present study demonstrates that potassium permanganate solutions, in conjunction with antibiotics and anti-inflammatories, may be beneficial in the treatment of dermatitis or ulcerative lesions caused by insects of the genus. However, further research is required to fully determine the complete benefits and any side-effects.
