[Migrant erythema as clinical presentation of cutaneous larva migrans in Mexico City].

Cutaneous larva migrans (CLM) is a ubiquitous self-limited skin eruption, most frequently caused by the larvae of dog and cat hookworms. Although CLM is most frequent in tropical climates, the infection is becoming more common in urban areas. CLM has been frequently misdiagnosed and/or treated inappropriately, and mimics rheumatic, infectious, vascular, or dermatologic diseases. We here in report the clinical presentation and management of 18 cases of CLM.
