Right atrial myxoma as the first manifestation of granulomatosis with polyangiitis, and a possible association with vascular endothelial growth factor (VEGF) and interleukin 6 (IL-6): a case report and review of the literature

Abstract

Background: Granulomatosis with polyangiitis and myxomas are rare conditions previously described to co-exist. Cardiac masses are often presumed to be myxomas rather than lesions of granulomatosis with polyangiitis. Case presentation: We present a review of the symptoms for the two diagnoses along with the first verified case. Conclusions: Two possible risk factors for developing myxomas (VEGF and IL-6) are explored and discussed.
