Eye myasthenia in a young togolese: about a case and literature review.

The authors report a case of ocular myasthenia revealed by a myasthenic crisis after antimalarial treatment with quinine in a 14-year-old girl. The patient's exploration by a chest scan had revealed a thymoma and the test of acetylcholine receptor antibodies was strongly positive. Finally, electromyography revealed a decrement greater than 10% to repetitive nerve stimulation. The interest of this issue lies in the rarity of this observation in Black Africa, where it is often confused with malaria.
