“…Myxomatous emboli were found in the reticular dermis of livedoid skin in a patient who developed LR after exercise-induced syncope. 67 The patient was found on echocardiography to have a left atrial myxoma. The syncopal episodes and LR resolved after removal of the myxoma.…”

“…The syncopal episodes and LR resolved after removal of the myxoma. 67 Primary amyloidosis has also been associated with the development of LR. 68 In the setting of bilevel positive airway pressure therapy, the development of LR is strongly suggestive of gas embolism.…”

“…This cutaneous manifestation may represent peripheral emboli from the vegetation, an association that has previously been reported in the literature 6 7. Although, in rare cases, atrial myxoma is also thought to be associated with livedo reticularis 8. Both variations in the microbiological cause, especially unusual organisms, and subsequently clinical presentation of IE, demand appropriate diagnostic screening.…”

Unusual cause of infective endocarditis in an elderly patient with a rare condition

A 77-year-old woman presented to the emergency department with a 1-week history of anorexia, fatigue, general malaise and a 3-day history of fever. Clinical examination revealed livedo reticularis across the anterior aspect of her knees and a pansystolic murmur. Laboratory evaluation found neutrophil leucocytosis; elevated C reactive protein and blood cultures grew Streptococcus acidominimus. Transthoracic echocardiography displayed vegetation on the mitral valve and a left atrial myxoma. She was treated with intravenous benzylpenicillin and erythromycin for the infective endocarditis (IE) and remains well 3 months post-treatment. S. acidominimus is considered a common veterinary pathogen rarely found in humans. To the best of our knowledge, only two prior reports of IE due to this organism exist in the literature. This case highlights how rare pathogens can cause unusual presentation and the importance of IE as a differential even in the absence of classical signs, if fever and new murmur are present.

“…It can also reveal an embolus within a dermal vessel (2)(3)(4). The demonstration of myxomatous emboli in a vessel can be difficult; therefore, repeating the biopsy or examining serial sections may be useful (8). Diagnosis is confirmed by echocardiography, and emergency surgery is carried out in order to remove the myxoma.…”
