Cutaneous myiasis.

Although cutaneous myiasis remains uncommon in North America, any traveler to the tropics may return with this ailment. A history of travel to a tropical country, a persistent pruritic lesion resembling a boil but having a dark central punctum with seropurulent or serosanguineous drainage, and complaints of a crawling sensation in the area of the lesion should lead the physician to consider myiasis. Treatment is directed at prompt removal of the fly maggot by incision and extraction.
