First case recognized as autoimmune polyglandular syndrome type 2 with myasthenia gravis in Palestine: A case report and literature review

BACKGROUND: Myasthenia gravis is an organ specific autoimmune disorder that is potentially serious but treatable. It is characterized by fatigability of the voluntary muscles and weakness caused by antibodies against the nicotinic acetylcholine receptor (AChR) on the postsynaptic membrane at the neuromuscular junction. Sometimes, and in very rare cases, it can be associated with other autoimmune conditions in a so called autoimmune polyglandular syndrome type 2, which consists mainly of autoimmune adrenal insufficiency (Addison's disease) with autoimmune thyroid disease and/or type 1 diabetes mellitus. CASE PRESENTATION: We describe a case of a 47-year-old male patient presenting with weakness, difficulty swallowing (mainly liquids) and dysarthria. He was discovered to have low cortisol and TSH levels with high T4 and T3. These findings lead to the suspicion of a more complex disease process and through a thorough research of literature we discovered an association between myasthenia gravis and autoimmune polyglandular syndrome specifically type 2 which fits with our patients’ presentation. CONCLUSION: In any autoimmune disease, it is important to keep in mind associations and susceptibilities to other autoimmune processes and syndromes in order to reach a correct diagnosis and treatment preventing life threating events.
