PathogenThis section has been translated automatically.
Various parasites can trigger the clinical picture of the"larva migrans cutanea syndrome". In this respect, the so-called larva migrans is not an independent clinical picture, but merely a clinical symptom.
In distinction to the larva migrans visceralis syndrome (e.g. triggered by Toxocara canis or Toxocara cati, the roundworms of dogs and cats) the term "larva migranscutanea syndrome" instead of larva migrans (larva migrans refers to the pathogen in the ordinary sense) is the better terminology.
- Larvae of horseflies
- Ankylostoma species (hookworms such as Ancylostoma brasiliense, Ancylostoma caninum etc. which are primarily pathogenic to animals and are a false host for humans)
- Strongyloides species
- Cordylobia anthropophaga (tumbu fly: Africa).
Occurrence/EpidemiologyThis section has been translated automatically.
Ankylostomatidae (esp. Ancylostoma brasiliens and caninum; Strongyloides stercoralis): The larvae of the above-mentioned nematodes (threadworms) actively bore through the skin when walking barefoot or lying on the beach. Sources of infection are beaches contaminated by dog and cat faeces and children's play areas. In contrast to Ancylostoma duodenale and Necator americanus, which cause systemic disease(ancylostomiasis), these species do not succeed in connecting to the vascular system in human skin. The consequence is a local (cutaneous) infestation with the clinical picture of the larva migrans cutanea syndrome.
Myiasis linearis migrans (especially arthropod larvae of the genus Gastrophilus): Fly larvae penetrated through the skin. Mostly occurring on African beaches (barefoot walk).
ManifestationThis section has been translated automatically.
Most common disease in tropical travelers; no age restrictions; more common in children and adolescents and younger adults.
LocalizationThis section has been translated automatically.
Mainly occurring on the lower extremities and glutaeal region, corresponding to the parts of the body that have been in contact with larval sand as found in tropical and subtropical areas. Rare is the infestation of the capillitium.
Clinical featuresThis section has been translated automatically.
Differential diagnosisThis section has been translated automatically.
The clinical picture with the itchy, bizarre ducts is diagnostic. In the rare follicular symptoms, bacterial folliculitis must be excluded.
External therapyThis section has been translated automatically.
1% ivermectin cream (off-label use; preparation - Soolantra® - is, however, approved for the treatment of rosacea) 2x daily for a period of 14 days.
Alternatively: 10%-15% Tiabendazole ointment(e.g. R254, Mintezol) under occlusion several times a day for 5-7 days. Note: Tiabendazol is often no longer available. If necessary, purchase via foreign countries.
Alternative: Albendazole 10% in Vaseline (apply 3 times daily to the affected areas)
Supplementary: if necessary, glucocorticoid supplementation in case of a strong inflammatory reaction or alternating therapy
Internal therapyThis section has been translated automatically.
According to the S1 guideline, a systemic therapy is the first choice.
Operative therapieThis section has been translated automatically.
Notice!Care must be taken to treat a sufficiently large area of skin (larvae 1-2 cm before the end of the corridor).
Progression/forecastThis section has been translated automatically.
Man is a false host; even untreated there is always spontaneous healing. But this can take months.
Note(s)This section has been translated automatically.
Hookworm folliculitis must always be treated systemically!
The visceral "larva migrans" caused by human pathogens often lacks the typical bizarre duct structures in the skin, resulting in organ infestation.
