Superficial, self-limiting dermatosis caused by migration of dog or cat hookworm larvae in the epidermis following invasion of the skin.
One of the most common parasitic infestations affecting travelers returning from beach destinations in the Caribbean, Mexico, Brazil, and Southeast Asia.
Characterized by intensely pruritic serpiginous or linear raised erythematous tracks. Lesions occur on unprotected skin (most commonly involving the feet) that has come into contact with sandy, moist soil contaminated by dog or cat feces containing hookworm eggs.
Diagnosis made on clinical grounds.
Although usually self-limiting, treatment with oral anthelmintic therapy speeds up resolution of symptoms and is considered curative.
