Summary:Intrafacial Synkinesis A 52-year-old man was admitted to the hospital with progressive weakness. Examination revealed involuntary unilateral ptosis that coincided with voluntary contraction of the lower facial muscles (shown in a video), a form of synkinesis known as the Marin-Amat syndrome. A 52-year-old man was admitted to the hospital with weakness that had progressed over a period of several weeks. Cranial-nerve examination revealed involuntary unilateral ptosis that coincided with voluntary contraction of the lower facial muscles, a form of synkinesis known as the Marin-Amat syndrome (see video). Symmetric proximal muscle weakness was present, and Gottron’s papules were also observed over the dorsum of the metacarpophalangeal joints. Laboratory data were notable for an elevated serum creatine kinase level of 51,000 U per liter (normal range, 55 to 170). A diagnosis of dermatomyositis was made; however, the finding of synkinesis could not be . . .
