Abstract

Ticks are parasites that usually suck the blood of wild or domestic animals; rarely, they ingest human blood and spread various febrile infectious diseases along with skin problems. Out of 40 cases of tick bite reported in Korea, only 3 were caused by nymphal ticks, and tick bites by nymphal Amblyomma testudinarium have not been reported previously. Herein, we report a rare case of tick bite by nymphal A. testudinarium. A 57-year-old woman presented with an asymptomatic solitary erythematous nodule on the left thigh that had been present for 6 days. The tick, which the patient removed from the lesion and brought to the hospital, was identified as a nymphal A. testudinarium. Doxycycline (200 mg) was used as treatment, and after seven days of use, the patient improved and no other lesions were detected.
