Cutaneous and pulmonary dirofilariasis due to Dirofilaria repens

Summary Dirofilariasis is a worldwide zoonotic infection that accidentally affects humans. It is caused by filarial nematodes of the genus Dirofilaria, which are transmitted by mosquitoes. Cutaneous dirofilariasis appears as inflammatory lesions that could be consistent with Wells’ cellulitis. We present a remarkable case of human infection with Dirofilaria repens, causing both subcutaneous and pulmonary nodules. What's already known about this topic?
