A case report of female vaginal myiasis

Abstract

Introduction and importance: Myiasis, a rare affliction, is distinguished by the infestation of human organs by larvae of the Diptera species. Although myiasis is commonly observed in the skin, eyes, ears, and nasopharynx, the occurrence of human genital myiasis is infrequent. Instances of vulvar and prolapsed uterus myiasis have been previously documented. Case presentation: In this study, the authors present a case of vaginal myiasis in a young female residing in the warm and humid climate of south China. The treatment approach involved manual extraction of the maggots and vaginal irrigation with a 0.01% potassium permanganate solution for 7 days. As 1 month followed up, she was cured and then changed residence, and the vaginal myiasis was not recurrence. Clinical discussion: In reported myiasis cases, mechanical extraction of maggots, debridement of necrotic tissue, and irrigation with antiseptic solutions, such as 1% ivermectin solution in propylene glycol were the treatment of myiasis. In this case, a low-concentration solution of potassium permanganate, serving as an oxidizing agent, was utilized as a vaginal douching agent, and had a good effect. Conclusion: Vaginal infestation of maggots likely occurred due to unsanitary intercourse in a suitable environment, removal of maggots and vaginal irrigation with low-concentration solution of potassium permanganate may be an effective therapy.
