[A case of primary toxoplasmosis in an immunocompetent patient]

A case of an immunocompetent patient presenting primary systemic toxoplasma infection involving the eye (condition seen in less than 3% of primary infections). The patient showed reactivation of this primary focus two years later.

Diagnosis of toxoplasm retinitis is based on a typical lesion consisting in an area of active retinitis adjacent to an inactive corioretinal scar. Differential diagnosis must consider other causes of retinal coroiditis in primary infection cases: sarcoidosis, tuberculosis, syphilis as well as viral and fungal infections. Ocular toxoplasmosis was confirmed by serum tests.
