[Toxocara canis infection. 2 cases of peripheral granuloma in adults].

PURPOSE
We report two cases of toxocariasis peripheral granuloma in adults.


METHODS
Diagnostic difficulties linked to parasite serologies, particular to these two cases, are presented. Serology is often poorly contributive, but PCA and/or vitreous study with the ELISA reaction to Toxocara canis homologous antigens in the endocular fluids are the most reliable means of reaching a diagnosis, as evidence in our two observations. In the same way, the presence of eosinophils and of IgE in the aqueous humor and or vitreous is of great importance for orienting the diagnosis.


RESULTS
The treatment consisted in systemic steroids and granuloma cryotherapy associated with vitrectomy and for one case indentation due to a traction. Later, retinal membrane peel was performed for the same patient. No treatment with antihelminthic drugs was proposed. The functional and anatomic results were good in both cases (8/10-P2 and 6/10-P2).


CONCLUSION
Toxocara canis infection is based on clinical aspects. The ELISA technique is useful for biological diagnosis.
