“…Seabather's eruption (SBE) is an acute dermatitis characterized by itchy and erythematous papules that appear during or after bathing in the sea. It is caused by contact with the larvae and adult of the jellyfish (Linuche unguiculata and L. aquila, recently found in the Philippines) and larvae of the sea anemone Edwardsiella lineata [1][2][3] . Limited information is available on this type of dermatitis.…”

“…Limited information is available on this type of dermatitis. However, it is considered a public health concern in Brazilian coastal areas [2][3][4][5][6][7] . Here, we report two typical cases of SBE characterized by exuberant and eczematous lesions, aggravated by diagnostic confusion with dermatophytosis and parasitic infestations such as cutaneous larva migrans and scabies.…”

“…Clinical and epidemiological diagnoses can be made. However, the absence of confirmatory laboratory examination findings can lead to diagnostic confusion [1][2][3][4][5][6][7] . Differential diagnoses, such as swimmer's itch and allergic reactions to insect bites, can be distinguished based on well-characterized clinical manifestations that appear during bathing in freshwater infested by Schistosoma Contact with sand on the beaches supported the diagnostic suspicion of ringworm and parasitic infestations, such as scabies and cutaneous larva migrans.…”

Dear Editor:Seabather's eruption (SBE) is an acute dermatitis characterized by itchy and erythematous papules that appear during or after bathing in the sea. It is caused by contact with the larvae and adult of the jellyfish (Linuche unguiculata and L. aquila, recently found in the Philippines) and larvae of the sea anemone Edwardsiella lineata 1-3 . Limited information is available on this type of dermatitis. However, it is considered a public health concern in Brazilian coastal areas 2-7 . Here, we report two typical cases of SBE characterized by exuberant and eczematous lesions, aggravated by diagnostic confusion with dermatophytosis and parasitic infestations such as cutaneous larva migrans and scabies.Envenomations occurred in a female and male children aged 2 and 11 years, respectively, who frequently went to the coastal beaches in the state of Santa Catarina, Brazil. The children experienced a pricking sensation in the pubic, genital, and gluteal regions during sea bathing, which progressed to pruritus and intensified at night.The parents of the one child consulted a pharmacist, who diagnosed the condition as ringworm and recommended the use of topical ketoconazole. After 1 week of treatment, the manifestations had worsened. Thus, the parents sought consultation from a dermatologist. The other child was taken by his mother to a pediatric emergency department. The condition was diagnosed as cutaneous larva migrans, and topical thiabendazole was prescribed and used for 2 weeks. However, due to the aggravation of pruritus and lesions, the child returned to the hospital for consultation from the same pediatrician who changed the diagnosis to scabies. Topical permethrin was prescribed, but the mother subsequently decided to consult a dermatologist.Both dermatological examinations revealed intense pruritic and eczematous, erythematous papules located mainly in the gluteal regions (Figures 1A, B, E, and F). Dermoscopic examinations did not reveal the structures of L. unguiculata or cnidocytes, and examination of areas with exulcerated and meliceric crusting revealed nonspecific findings (Figures 1C, D, G, and H).The patients were treated with systemic antihistamines and corticosteroid creams. The condition of both the patients improved, with complete regression of the lesions and pruritus after 15 and 21 days of treatment, respectively.The occurrence of SBE among individuals living on the Brazilian coast is caused by the planulae and the scyphomedusa L. unguiculata, which is found on the Santa Catarina coast 2-8 . Limited information is available of this type of dermatitis, and its occurrence is mainly observed in individuals living on the coastlines of São Paulo and Santa Catarina 3-7 . In this study, the initial clinical manifestations, which include erythematous, itchy papules that appeared during exposure to seawater, particularly in areas covered by bathing suits, with a gradual increase in itching, were typical of SBE in children 1-7 .Clinical and epidemiological diagnoses can be made. However, the absence ...

erythematous plaques as in the two reported cases. Larvae with 0.2-0.5 mm in diameter are found in the water columns and penetrate the areas covered by bathing suits, including neoprene clothes, seeking shelter to metamorphose. 1-8 The fabrics of the clothes act as a filter draining the water with the trapping and disruption of the planulae against the skin activating its defence cells (cnidocytes). The toxins cause erythematous and pruriginous papules in coert areas of the body. Children are more affected than adults by staying longer in the sea.Koebner Phenomenon was described in 1871 by Heinrich Koebner in a patient with the development of psoriatic plaques in areas of multiple trauma. 10 Isomorphic phenomenon or KP can be triggered by several factors, especially trauma, and is reported in various dermatoses. 10 In this series, the linear distribution of erythematous papules resembles KP. These linear lesions are unlikely to occur at random, or by linear contact of the planulae with the skin. It is more likely that the papules with linear distribution appeared during or after the scratching and were triggered by trauma. We conclude that the observations support the inclusion of SBE in the list of KP triggering diseases.
