Cutaneous manifestations of infective endocarditis as presenting signs of left atrial myxoma in a patient with acute ischemic stroke: A case report.

RATIONALE: Approximately one-fifth ischemic stroke are attributed to cardioembolism. Patients with cardioembolic stroke often develop a more severe disability and a higher risk of stroke recurrence. Cardiac myxoma, although uncommon, can serve as a potentially curable cause of acute embolic strokes.

PATIENT CONCERNS: A 55-year-old male patient presented to the emergency department with acute vertigo and unsteady gait, accompanied by left upper limb numbness. Concurrently, purple-like lesions on the left hand were noticed.

DIAGNOSES: Brain magnetic resonance imaging showed multiple infarctions in the posterior circulation. Additionally, skin examination showed Janeway lesions, Osler nodes and splinter hemorrhages. There was no evidence of systemic infection. Subsequently, transthoracic echocardiogram revealed a left atrial myxoma.

INTERVENTION: Early surgical resection of cardiac myxoma was performed.

OUTCOMES: The patient recovered well from the surgery. No recurrent embolic event was reported at 3-month postoperatively.

LESSONS: Clinicians should be vigilant for skin manifestations of cardiac embolism. In patients with acute ischemic strokes, the presence of cutaneous embolic phenomena could serve as a warning sign of cardioembolism.
