A 17-year-old girl attended the department on her return from a holiday in Spain. She related the development of a lump on the side of her foot which progressed over a few days to a red itchy line. She could not recall any particular trauma, bite or sting. Throughout the week she had remained well. In Malaga, she received anonymous oral medication without effect. During her holiday she did not walk on a beach, although she recalled walking barefoot in a botanical garden. On examination there was an irregular line, 5 cm in length, uniformly erythematous on the lateral aspect of her tanned right foot. There were no signs of excoriation, lymphangitis, or regional lymphadenopathy. Clinically she was well and apyrexial. From his elective, the SHO was familiar with the skin track as being typical of cutaneous larva migrans. Chlorpheniramine 4 mg PO TDS
