Introduction: Chorea is an extrapyramidal hyperkinetic syndrome. Differential diagnosis is very wide and includes hereditaries and acquired disorders. Clinical case: We present the case of a 68-year-old man at the Emergency Department with orolingual, cervical and limbs movements, not stereotyped or voluntaries. We excluded main causes of chorea. However, we discover a persistent thrombocytosis in previous hemograms. Genetic tests will demonstrate a JAK-2-V617F mutation. Conclusions: Myeloproliferative disorders are a few known causes of chorea. Clinic course is usually favourable if the hematologic condition is treated.
