Atypical eczema-like skin symptoms and joint swelling in a patient with Toxocara seropositivity - Case Report.

Abstract

Introduction: Toxocariasis is the most widespread zoonotic parasitic infection, shared between humans, dogs, and wild canids. Clinical manifestations vary widely, often leading to delayed diagnosis, with allergic skin reactions and joint swelling being less common.

Case report: A 53-year-old man presented wityh unusual allergic skin symptoms, including a rash, blisters, and joint swelling. The symptoms occurred intermittently over several years.

Results: Extensive testing yielded negative results, with the exception of anti-Toxocara antibodies, suggesting that Toxocara infection may have contributed to the symptoms or triggered an inflammatory response in the host. Albendazole therapy was initiated, resulting in an improvement in the skin symptoms.

Conclusions: This cosmopolitan parasitic disease should always be considered in the diagnosis of allergic skin changes and joint swelling. Serological testing plays a crucial role in the diagnostics.
