[Stevens-Johnson's syndrome after treatment for ocular toxoplasmosis]

We present a case of a 9 year-old male, who was treated with sulfadiacine, pirimetamine and folinic acid following diagnosis of an active toxoplasmic chorioretinitis. After 9 days of treatment he developed serious multiorganic mucocutaneous lesions and was diagnosed with Stevens-Johnson's syndrome.

Stevens-Johnson's syndrome is a potentially fatal multiorganic disease, where drugs are clearly linked as causal factors. Fifty per cent of cases progress to severe ocular disease. The multiorganic aspect of the disease and its severity demand an early diagnosis and a multidisciplinary treatment.
