Cutaneous larva migrans with folliculitis: report of seven cases and review of the literature.

Seven patients (four men, three women, mean age 31 years), all returning from the tropics, presented with pruritic folliculitis and creeping eruption. The folliculitis consisted of 20-100 follicular papules and pustules confined to a particular area of the body, mainly the buttocks. The creeping eruption consisted of two to 10 serpiginous or linear burrows 1-5 cm long located either in the same area or in a different area from the folliculitis. Five patients were cured with one to three courses of ivermectin (one course in two cases, two courses in two cases and three courses in one case) and two patients were cured with a 3-day regimen of albendazole. Folliculitis should be added to the dermatological manifestations of cutaneous larva migrans. Treatment is more difficult than in classical forms of cutaneous larva migrans.

[Clinical study of ten cases with acute abdomen after eating raw firefly squid (Watasenia scintillans, Hotaruika), which are probably due to type X larvae of the suborder spirurina].

We studied ten cases with abdominal pain after eating raw firefly squid, Watasenia scintillans, Hotaruika. Characteristic clinical features were abdominal pain, nausea, vomiting, diarrhea, creeping eruption and ileus with ascites. In ten patients, there were all cases with abdominal pain, nine with nausea and vomiting, four with diarrhea, one with creeping eruption, six with ileus. Laboratory examination revealed eosinophilia on peripheral blood in ten cases and high serum IgE value in nine cases. The infection rate of type X lavae of the suborder spirurina in Watasenia scintillans is almost 3%, so we measured the antibody to type X larvae of the suborder spirurina in nine patients by indirect fluorescent antibody method and the antibody titer was positive in seven cases. Most patients recovered in several days from first visit. But one patient was diagnosed peritonitis and operated with partial ileectomy. Pathological finding of resected specimen showed an erosion in the mucosal layer and an inflammation with marked eosinophilia in the submucosal layer. These results suggest that abdominal complaints after eating Watasenia scintillans are due to type X larvae of the suborder spirurina.

Larva currens: the usefulness of the agar plate method.

Creeping eruption caused by Strongyloides stercoralis is called larva currens, while those caused by other parasites are called larva migrans. To detect the parasite, the direct smear method was used. However, this method is not very sensitive in detecting S. stercoralis. A 62-year-old male with polyarteritis nodosa cutanea had an erythematous creeping eruption in various regions, such as his lumbar region, abdomen and thigh. The diagnosis of larva currens was made by the clinical appearance and the detection of S. stercoralis in his feces using the direct smear method and the agar plate method. This is the first reported case of larva currens in Japan. The agar plate method was useful and more sensitive than the usual direct smear method for detecting the S. stercoralis in feces and for elucidating the effects of treatment with antiparasitic drugs.

Imported cutaneous gnathostomiasis: report of five cases.

Gnathostomiasis has rarely been described outside endemic countries. We report on a series of 5 patients (4 females, 1 male, mean age 42.2 years) who returned to France from South-East Asia and presented with cutaneous gnathostomiasis. The cutaneous lesions appeared within a mean period of 62 d (range 10-150 d) after return. They consisted of creeping eruptions in 3 patients (in addition one also had papules, one had nodules and hepatitis, and one had hepatitis; all 3 had profound asthenia) and recurring migratory swellings in 2 patients. The mean eosinophil count was 1546/mm3 (range 398-3245/mm3). Diagnosis was based on positive serological tests in 3 patients and seroconversion in 2 patients, and was confirmed by identification of Gnathostoma hispidum in a biopsy specimen from one of the seropositive patients. Albandazole (1-4 courses) was given as treatment. Recurrences may occur up to 24 months after apparent cure without reinfection. Gnathostomiasis should be considered when patients return from tropical countries and present with migratory swellings or creeping eruption that does not respond to the usual treatment for cutaneous larva migrans. Serological tests may be negative initially and thus need to be repeated to check for seroconversion. Treatment may require multiple courses of albendazole and a prolonged period of follow-up is necessary before cure can be confirmed.

[Larva migrans].

Larbish, cutaneous larva migrans or creeping eruption, is a serpiginous cutaneous eruption caused by skin penetration of infective larva from various animal nematodes. Hookworms (Ancylostoma brasiliense, A. caninum) are the most common causative parasites. They live in the intestines of dogs and cats where their ova are deposited in the animal feces. In sandy and shady soil, when temperature and moisture are elevated, the ova hatch and mature into infective larva. Infection occurs when humans have contact with the infected soil. Infective larva penetrate the exposed skin of the body, commonly around the feet, hands and buttocks. In humans, the larva are not able to complete their natural cycle and remain trapped in the upper dermis of the skin. The disease is widespread in tropical or subtropical regions, especially along the coast on sandy beaches. The diagnosis is easy for the patient who is returning from a tropical or subtropical climate and gives a history of beach exposure. The characteristic skin lesion is a fissure or erythematous cord which is displaced a few millimeters each day in a serpiginous track. Scabies, the larva currens syndrome due to Strongyloides stercoralis, must be distinguished from other creeping eruptions and subcutaneous swelling lesions caused by other nematodes or myiasis. Medical treatments are justified because it shortens the duration of the natural evolution of the disease. Topical tiabendazole is safe for localized invasions, but prolonged treatment may be necessary. Oral thiabendazole treatment for three days is effective, but sometimes is associated with adverse effects. Trials using albendazole for one or four consecutive days appear more efficacious. More recent trials using ivermectine showed that a single oral dose can cure 100% of the patients; thus, this drug looks very promising as a new form of therapy. Individual prophylaxis consists of avoiding skin contact with soil which has been contaminated with dog or cat feces. Keeping dogs and cats off the beaches is illusory in tropical countries.

Souvenir from the Hamptons - a case of cutaneous larva migrans of six months' duration.

Cutaneous larva migrans is a distinctive serpiginous eruption caused by a reaction to burrowing hookworms. The infection is usually self-limited, normally lasting 2-8 weeks, but may persist for more than a year if misdiagnosed. Biopsies of the creeping eruption rarely reveal an organism. Thus, it is important for the infection to be recognized clinically, so that effective treatment may begin. We found topical thiabendazole to be fast and effective in treating this case of cutaneous larva migrans of six months' duration.

Hazards of domestic pets. Ringworm and other skin conditions.

Domestic pets may be responsible for a number of skin eruptions in man. Whilst ringworm due to Microsporum canis is one of the most common of these conditions in this country, trichophyton infection, flea bite dermatitis, cheyletiella dermatitis, canine scabies and traumatic dermatitis are by no means rare. Less frequently encountered conditions include creeping eruption, favus, fowl-mite dermatitis and allergic dermatitis.

Skin penetration of infective hookworm larvae. II. The path of migration of infective larvae of Ancylostoma braziliense in the metacarpal foot pads of dogs.

The hairless metacarpal foot pads of six hookworm-free puppies were exposed to infective larvae of Ancylostoma braziliense. Serial sections of the biopts stained with Harris' haematoxylin and eosin showed that the infective larvae are able to penetrate the toughest region of canine skin. Pores of eccrine sweat glands did not seem to constitute sites of entry and no larvae were detected in these glands. Larvae were only observed in the epidermis. The histopathology of the infected skin of the foot pads of the puppies was similar to that in human skin with "creeping eruption" as described by Fülleborn (1927). The biopts appeared to consist of hairy skin as well. In the unexposed adjacent hairy skin of the foot pads, larvae were also observed. They were found in the epidermis, hair follicle systems and dermis, suggesting that the migration from the epidermis into deeper tissue depends on the presence of the hair follicle systems.

Cutaneous larva migrans in northern climates. A souvenir of your dream vacation.

Three young women recently returned to the metropolitan Detroit area with cutaneous larva migrans. All three had vacationed at a popular club resort on the Caribbean island of Martinique. Cutaneous larva migrans is frequently seen in the southern United States, Central and South America, and other subtropical areas but rarely in northern climates. Several organisms can cause cutaneous larva migrans, or creeping eruption. The larvae of the nematode Ancylostoma braziliense are most often the causative organisms. Travel habits of Americans make it necessary for practitioners in northern climates to be familiar with diseases contracted primarily in warmer locations. The life cycle of causative organisms and current therapy are reviewed.

Cutaneous larva migrans: clinical features and management of 44 cases presenting in the returning traveller.

BACKGROUND: Cutaneous larva migrans (CLM) is the result of a nematode infection, and shows a characteristic creeping eruption. As travel to the tropics increases, many British citizens may be returning with this infection, which is often misdiagnosed or treated incorrectly. OBJECTIVES: To perform a retrospective survey of 44 cases of CLM presenting to the Hospital for Tropical Diseases in London over the last 2 years. METHODS: Cases were reviewed with regard to patient characteristics, source of infection, source of referral, clinical features and therapy. RESULTS: Most infections were acquired in Africa (32%), the Caribbean (30%) and South-east Asia (25%), but also in Central and South America. There was a history of exposure to a beach in 95% of patients and the median duration of symptoms was 8 weeks (range 1-104). Lesions mainly affected the feet (39%), buttocks (18%) and abdomen (16%), but the lower leg, arm and face were also affected. Multiple lesions were seen in seven of 44 cases (16%). Laboratory abnormalities were absent in all patients. Of 44 patients seen, four needed no treatment, 28 were cured by a single course of treatment, 11 required a second course of therapy and one patient was treated three times. Thirty-one patients received oral albendazole 400 mg daily for 3-5 days and 24 were cured (77%). Five patients received 10% thiabendazole cream topically for 10 days and four were cured (80%). Four patients received oral thiabendazole 1.5 g daily for 3 days and all required further therapy. CONCLUSIONS: In view of the range of treatment regimens recorded, a randomized controlled trial comparing topical and systemic therapies is warranted.

Human gnathostomiasis caused by Gnathostoma doloresi, with particular reference to the parasitological investigation of the causative agent.

Gnathostomiasis caused by Gnathostoma doloresi Tubangui was observed in a 46-year-old Japanese man, a clerk, who resided in the Fukuoka prefecture of Kyushu district, in southern Japan. The first symptom noted by the patient was epigastric pain, which occurred 3 days after he had consumed the raw flesh of a brook trout, Oncorhynchus masou masou (Brevoort), from a trout farm in neighbouring Kumamoto prefecture. Three days later, he developed creeping eruptions on his trunk. The eruptions spread and the patient was admitted to hospital 18 days after eating the trout. No nematode larvae were found in any of four skin biopsies collected on admission. However, vesicles appeared on the lower abdomen of the patient 20 days after he had eaten the trout, and a small nematode was removed from one of them. One day after the nematode had been excised, a cutaneous swelling suddenly occurred on the patient's lower left jowl and this persisted for a week. All the skin abnormalities gradually decreased from day 25 post-ingestion and had disappeared by day 30. The isolated nematode was identified as an advanced third-stage larva of G. doloresi, based on its morphology and the number of hooklets on its head-bulb.

A study in a community in Brazil in which cutaneous larva migrans is endemic.

BACKGROUND: Cutaneous larva migrans (CLM) is a common but neglected parasitic skin disease in impoverished communities of the developing world. METHODS: To describe the clinical features and the morbidity associated with CLM, active-case finding was performed during rainy and dry seasons in a rural community in the state of Alagoas, Northeast Brazil. RESULTS: A total of 62 individuals received a diagnosis for CLM, and among them there were a total of 75 larval tracks. The number of tracks per person ranged from 1 to 3. Children <9 years old were affected significantly more often than other age groups (P<.001). Children had their lesions mainly on the buttocks, genitals, and hands, whereas in older patients, the majority of lesions were located on the feet. Twenty-four percent of the 75 lesions were superinfected. Bacterial superinfection was more common among children. All but 1 patient complained about itching, and 84% of the 62 patients complained about sleep disturbances. Itching was classified as being severe by 61% of patients. Approximately 40% of the 62 patients had attempted to treat their creeping eruption previously. Larvae moved forward 2.7 mm per day. There was a significant correlation between the length of the track and the duration of infestation ( rho =.53; P<.0001). CONCLUSIONS: CLM is a common parasitic skin disease in this rural community, with different topographic patterns of lesions in children and adults. CLM is associated with considerable morbidity. The length of the track can be used to estimate the duration of infestation.

Cutaneous larva migrans in travelers: synopsis of histories, symptoms, and treatment of 98 patients.

The symptoms, medical history, and treatment of 98 patients with cutaneous larva migrans (creeping eruption) who attended a travel-related-disease clinic during a period of 4 years are reviewed. This condition is caused by skin-penetrating larvae of nematodes, mainly of the hookworm Ancylostoma braziliense and other nematodes of the family Ancylostomidae. Despite the ubiquitous distribution of these nematodes, in the investigated group only travelers to tropical and subtropical countries were affected; 28.9% of the patients had symptoms for > 1 month, and for 24.5% the probable incubation period was > 2 weeks. The efflorescences typically were on the lower extremities (73.4% of all locations). The buttocks and anogenital region were affected in 12.6% of all locations, and the trunk and upper extremities each were affected in 7.1%. Only a minority of patients presented with eosinophilia or an elevated serum level of IgE. No other laboratory data appeared to be related to the disease. Therapy with topical thiabendazole was successful for 98% of the patients. Systemic antihelmintic therapy was necessary in two cases because of disseminated, extensive infection.

Gnathostomiasis: clinicopathologic study.

Gnathostomiasis is a systemic parasitic disease that is caused by the ingestion of contaminated raw fish, the intermediate host. Involvement of the skin is a common event, and when it does happen, it can produce a superficial or creeping eruption, pseudofurunculosis, and nodular migratory panniculitis. We carried out a retrospective study of 946 cases of gnathostomiasis; 66 of them had skin biopsies. The diagnosis was made based on clinical and epidemio-logic findings as well as the therapeutic response. The most common skin finding was nodular migratory panniculitis affecting the trunk. Most of the patients were males between 20 and 40 years of age. Histopathologically, we were able to see the larva and make a definitive diagnosis in 15 cases, and in 12 cases, the worm was retrieved during the surgical procedure. In remaining cases, despite of our inability to identify the larva, the histopathologic changes were quite characteristic and included: dermal and hypodermal edema with dense mixed infiltrates composed of eosinophils admixed with lymphocytes and neutrophils, eosinophilic vasculitis, flame figures, areas of necrosis, and hemorrhage. Thus, the presence of these histopathologic features in the context of a clinical picture suggestive of gnathostomiasis allows the pathologist to make the correct diagnosis.

Extensive cutaneous larva migrans with folliculitis mimicking multimetameric herpes zoster presentation in an adult traveler returning from Thailand.

Hookworm-related cutaneous larva migrans (CLM) is a frequent cutaneous disease among travelers returning from the tropics. It can be misdiagnosed or treated incorrectly. We present a 42-year-old French patient who contracted the disease during a holiday in Thailand and who experienced an extensive CLM syndrome with a less frequent abdominal localization and a pseudo-multimetameric homolateral topography. The condition was late diagnosed and secondarily efficiently cured by a unique administration of ivermectin. Simple anamnestic information--often revealing beach activities--and clinical aspect of the creeping eruption allow to prevent diagnosis delay and to avoid aggressive or inadequate intervention.

Strongyloides stercoralis infection in former Far East prisoners of war.

Out of 602 consecutive people who had been prisoners of war in the Far East and were screened for tropical diseases, 88 (15%) were found to have Strongyloides stercoralis infection a mean period of 30 years after their return from the tropics. The classical strongyloid creeping eruption was the most common symptom (84%), while gastrointestinal disturbances were rare (5%). Thiabendazole was highly effective in eradicating the infection. Strongyloidiasis is an important condition, as when the host is immunosuppressed fatal hyperinfection may occur. Many undiagnosed cases of strongyloidiasis must exist among former prisoners of war, and it is thus important to identify and treat these patients.
