Tungiasis: An Underdiagnosed Problem

Tungiasis is a cutaneous ectoparasitosis caused by the flea parasite Tunga penetrans, prevalent in South America, the Caribbean, and sub-Saharan Africa. Clinically it is characterized by the formation of single or multiple papules with a translucent whitish halo and a brownish-black central region, frequently located on the feet. The lesions may present with itching or mild pain, with bacterial superinfection being the most frequent complication. The diagnosis was made based on the clinical characteristics of the lesions in a patient from endemic areas. The treatment of choice is surgical removal of the flea followed using topical antimicrobials and tetanus vaccination. Prevention is essential with the use of closed footwear and repellents.
