ABSTRACT

Myasthenia gravis is an autoimmune neuromuscular disorder of neuromuscular transmission produced by the decrease of the acetylcholine receptors numbers of motor plaque, which is characterized by fluctuating muscle weakness and fatigue, mainly from innervated muscles by the cranial pairs. Its manifestation is evident during continuous activity and it improves after periods of rest or by the administration of anti-cholinesterase medications. A case of a 79 year-old black male with mellitus type II diabetes antecedents who is controlled by means of a diet is presented. At about two months he noticed a drooping of the right eyelid first and the left later. Also, he has difficulty in swallowing, basically, solid food and during the day he feels muscular weakness, so he visits the doctor. In the physical examination bilateral ptosis is observed, paralysis of the third pair in its extrinsic portion.
