Paraneoplastic acral vascular syndrome in a patient with non-small cell lung adenocarcinoma with KRAS G12A oncogenic mutation.

Paraneoplastic acral vascular syndrome (PAVS) is a rare condition characterised by signs of digital ischaemia, including Raynaud's phenomenon, acrocyanosis and digital gangrene, in the context of an underlying neoplastic process. Prompt recognition of this syndrome, as well as accurate identification and classification of the associated neoplastic condition, are crucial.This report describes the case of a woman diagnosed with PAVS secondary to stage IV non-small cell lung adenocarcinoma harbouring a Kirsten Rat Sarcoma viral homolog oncogene (KRAS) G12A mutation (p.Gly12Ala).
