ABSTRACT
Larva currens is the cutaneous manifestation of human infection with the geotropic helminth Strongyloides stercoralis. Strongyloidiasis is a lifelong infection unless treated. A high index of suspicion is needed to prevent chronic symptoms of strongyloidiasis (eg, larva currens, eosinophilia, abdominal discomfort) and to prevent fatal dissemination. We present a case of chronic larva currens following tourist travel to the Gambia and Southeast Asia>20 years ago. This case highlights several important features of larva currens and strongyloidiasis, including the chronicity of symptoms, the rapidity of the migratory serpiginous rash, and the absence of high-grade eosinophilia.

We report an uncommon case of a primary Echinococcus cyst that developed in the subcutaneous tissue of the right popliteal fossa, at the spot of a previous wasp sting, suggesting the possibility of an unusual transmission of the eggs by insects. This unusual presentation was initially considered as a Baker cyst until parasytological results verified Echinococcus hydatidosus, the larval form of Echinococcus granulosus, as diagnosis. However, the most common path of Echinococcus granulosus infection is through contact with a definitive host or by ingestion of ova through contaminated water or food. Transmission by insects should also be reconsidered in endemic areas.

The authors report a case of knee acute arthritis with intra-articular presence of microfilariae D. medinensis observed in a black African worker immigrated in France. It is a classical manifestion of dracunculosis articular complications which are however less frequent than intra-articular reaction arthritis without microfilariae, or than pyogenes arthritis due to neibourhood superinfections. The authors emphasize the significance of a double clinical and immunological supervision in the course of a convenient treatment including antibiotics, anti-inflammatory agents, local treatment, and rehabilitation.
