Respiratory distress in a patient with Klinefelter syndrome: a suspicion of COVID-19 hiding severe pulmonary embolism.

Klinefelter syndrome is the most common congenital abnormality causing primary hypogonadism and predisposing to a state of hypercoagulability. We report the case of a 37-year-old man, of Algerian nationality, diagnosed with Klinefelter syndrome admitted to the hospital via the emergency room for acute chest pain and dyspnea. The patient arrived in Tunisia 36 hours ago.
