Intense pulsed light is potentially an effective light source for PDT. However, the determination of complete remission in actinic keratosis requires caution, and long-term follow-up or histologic confirmation may be required.

Abstract:A 15-year-old boy, who had recently arrived back from a trip to Cambodia for a missionary camp, presented with several serpiginous thread-like skin lesions that began as small papules on the left upper extremities 2 weeks before his visit to Hospital. The skin lesions were pruritic and erythematous, and had migrated to the chest and abdomen. The histopathological findings showed only lymphocytic and eosinophilic infiltrations in the dermis of the biopsied skin lesion. The patient's serum reacted strongly to the Ancylostoma caninum antigen by an ELISA method. Therefore, he was diagnosed with cutaneous larva migrans by A. caninum. After the oral administration of albendazole and ivermectin, the skin lesions resolved without recurrence. This is the first reported case of a cutaneous larva migrans caused by Ancylostoma canimum diagnosed serologically using ELISA in Korea. et al., 1995;Lim et al., 1996;Chang et al., 1999;Kim et al., 1999;Suh et al., 2003). We report a case of CLM due to A. caninum that was believed to be the result of an infection obtained in Cambodia during a missionary camp and was diagnosed serologically using ELISA. CASE RECORDIn July 2002, a 15-year-old boy visited the Seoul National University Hospital with a skin eruption on his left upper extremity, chest and abdomen, which had been presented for 2 weeks. The skin lesions were linear, serpiginous, elevated and erythematous (Fig. 1). It produced an intense itching sensation, and scaly plaque was observed on the surface of the lesions. He had returned from a trip to Cambodia for a missionary camp one week before the skin lesions erupted, but he denied any risk activities of cutaneous larva migrans such as walking barefoot on the ground or sun-bathing at the beach during his stay in Cambodia.The laboratory findings revealed an increased number of WBC (19,060/mm 3 ) with a normal eosinophil count and normal serum IgE level. A stool examination showed no eggs of the parasites and the chest X-ray was within the normal limits. A pathological examination on the biopsied specimen showed only dermal patchy infiltrations of 234 Korean J. Parasitol. Vol. 41, No. 4. 233-237, December 2003 Fig. 1. Erythematous linear elevated serpiginous plaques on the left upper extremities (A) and the abdomen (B).
