Thrombotic complications of SARS-CoV-2 have been increasingly recognized as an important component of COVID-19 in adults; however, they have been less evident in children. We report a case of a teenager with positive SARS‐CoV‐2 RT–PCR and underlying prothrombotic risk factors, including aromatase inhibitor therapy, who developed deep vein thrombosis resulting in pulmonary embolism. Laboratory tests revealed deranged coagulation parameters (high D-dimers and Factor VIII and low antithrombin). The patient required intensive care and was managed with anticoagulants, dexamethasone and antithrombin concentrate. Clinical condition and hemostatic profile gradually improved. A review of the available literature for similar cases is presented.
