  • We present a case where this infection was successfully treated and review the available literature. Cases may present many years after they have left an area endemic for Strongyloides infection, emphasizing the need for a full travel history.[doi.org]
  • All patients answered a rigorous questionnaire at each medical appointment during the follow-up, thus guaranteeing the absence of parasite reexposure risk (ie, travel to the endemic area).[doi.org]
  • With so little rigorous data from drug trial treatment of CNS toxocariasis and several cases of spontaneous remission, only tentative conclusions can be drawn from the reported outcomes.[dx.doi.org]

  • Among these, 52 patients (61.9%) reported skin-related problems (pruritus, urticaria, angioedema, and/or rash). Forty-nine patients (58.3%) had asthma, and 73.8% had allergic rhinoconjunctivitis.[ncbi.nlm.nih.gov]

  • The symptoms can include diarrhea, enteropathy with malabsorption, skin rashes, such as larva currens, or urticaria. In the context of pulmonary disease, hypereosinophilia is common. Finally there can be massive strongyloidiasis with dissemination.[coursera.org]
  • The rash, likely an allergic response to the migrating filariform larvae, often manifests as a pruritic wheal or linear urticaria.[emedicine.medscape.com]
  • CLINICAL PRESENTATION The classically recognized triad of symptoms in chronic strongyloidiasis are urticaria (episodic, rapidly moving urticarial skin eruptions, most often on the buttocks and perianal area), abdominal pain and diarrhea.[aafp.org]
  • Strongyloidiasis, a gastrointestinal infection by the helminth Strongyloides stercoralis, and Infective Dermatitis associated with HTLV-1 (IDH), appear to be risk factors for the development of HTLV-1 related diseases.[ncbi.nlm.nih.gov]
  • Invading larvae cause transient dermatitis. Larvae migrating through the lungs may provoke cough, hemoptysis, and dyspnea, but most infections do not lead to pulmonary symptoms.[histopathology-india.net]
  • Can cause dermatitis and balanoposthitis due to percutaneous entry, or diarrhea when the intestinal infection is very heavy. In kangaroos it is a stomach parasite causing gastritis.[medical-dictionary.thefreedictionary.com]
  • Delusional parasitosis is sometimes difficult for doctors to diagnose because many actual skin disorders, such as allergies, dermatitis, or real parasites, also cause the itching sensations.[merckmanuals.com]
  • CLINICAL PRESENTATION Patients may develop dermatitis when filariform hookworm larvae penetrate the skin.[aafp.org]


  • Seroconversion is likely valuable for the diagnostic workup ( 247 ). The use of purified antigens, the study of class or isotype response, and extensive standardization studies are necessary to improve molecular diagnosis in NSM.[dx.doi.org]
