Introduction: Multiple autoimmune syndrome (MAS) is a rare condition, first described by Humbert and Dupond in 1988 and characterised by three or more autoimmune disorders in the same individual.

Case description: Here we present a case of 14-year-old female patient diagnosed with ocular myasthenia gravis. The diagnosis of Graves’ disease was suspected on the basis of hyperthyroidism symptoms and confirmed by undetectable TSH level (<0.01 mUI/l) with high FT4 level (27.8 pmol/l). The adrenal insufficiency was suspected also clinically (extreme fatigue, weight loss, hyperpigmentation and low blood pressure) and accepted with a low cortisol level (37.4 ng/ml). The patient has improved after taking an anticholinesterase agent and corticosteroid replacement therapy. For the hyperthyroidism, a radical treatment is recommended and the Beta-blockers should be avoided.

Conclusion: The MAS-3 in our case is characterized by the association of myasthenia gravis, Graves’ disease and adrenal insufficiency in which every condition has a different treatment and prognosis in addition to a multidisciplinary care.
