Tungiasis in Italy: An imported case of Tunga penetrans and review of the literature

Tungiasis is an animal and human parasitic disease caused by fleas of the genus Tunga (Siphonaptera, Tungidae), endemic in equatorial and subtropical regions and rarely described in European countries, where clinicians and general pathologists could be not aware of this parasitic disease.To our knowledge, only 75 cases of human tungiasis (not all described in detail) were previously reported in Italy.We described a new case in a 34-year-old Italian flight attendant who developed a granuloma-like, ulcerated nodule in the subungual region of his left 5th toe, partially detaching the nail, about 20–30 days after his return from Brazil.We performed a detailed review of the literature of the Italian cases, suggesting the use of histochemical stains (especially Trichrome stain) in order to underline parasitic details.Tourism in endemic regions and globalization may result in new cases in developed countries and previously unaffected regions, therefore pathologists should consider this parasitic disease.
