LCV is an immune-mediated small-vessel vasculitis characterised by palpable purpura, often triggered by drugs, infections, or autoimmune conditions. Here, we present the case of a 53-year-old female with a history of rheumatic heart disease and mechanical mitral valve replacement who developed LCV after 5 years on acenocoumarol. The reaction persisted despite adjunct therapy and worsened upon switching to warfarin, suggesting possible cross-reactivity between these coumarin derivatives.
