RESUMO
Stings due to jellyfish, sea anemones, and corals are the most common envenomations encountered with humans in the marine environment. The first case was a 36-year-old female who presented with multiple whiplike linear, dark reddish bullous eruptions on the right forearm after she was stung by a jellyfish in the Philippines 15 days previously. The patient was treated with oral antibiotics for 10 days, but severe pruritus persisted and new papular lesions developed on her hand. Antibiotic therapy was discontinued and oral and topical corticosteroid therapy was applied instead. The skin lesions disappeared without recurrence after about 4 weeks. The second case was a 29-year-old male who visited our department with linear, reddish patches and necrotizing blisters on both the arms, left thigh, and trunk after he was stung by a jellyfish in Thailand. We treated him with oral and topical corticosteroids for 10 days and the lesions cleared. We describe two typical cases of jellyfish sting that are rare in Korea.
