Heerfordt-Waldenström Syndrome, A Rare Presentation of Sarcoidosis in a Patient with Old Ocular Toxoplasmosis.

Abstract

There are similarities between the ophthalmic presentation of toxoplasmosis and sarcoidosis, and there are some concerns of immunosuppressive treatments for sarcoidosis, which may lead to T. gondii reactivation. We report a rare case with acute sarcoidosis (Heerfordt- Waldenström syndrome) with a history of ocular toxoplasmosis from the North of Iran. The patient was a 36-year-old woman with left painful eye and swollen parotid, right facial paresis, maculopapular rash in left eyebrow and erythema nodosa on both legs. Anti-Toxoplasma IgG antibody was positive, and IgM was not detectable. Radiographic findings on the chest revealed bilateral hilar lymphadenopathy. The initial treatment was sulfamethoxazole- trimethoprim to prevent the recurrence of retinal toxoplasmosis and corticosteroid and mycophenolate mofetil for sarcoidosis. The patient showed clinical and vision improvement without recurrences during three months follow-up. Ophthalmological examinations and laboratory tests to rule out toxoplasmosis could be considered in known cases of sarcoidosis, particularly in ocular sarcoidosis status. To the best of our knowledge, this is the first report of comorbidity of ocular toxoplasmosis/sarcoidosis from Iran and possibly the world.
