He developed a macular\u2010papular rash which rapidly progressed into purpura, necrosis and peri\u2010orbital oedema. Investigations demonstrated severe haemolytic anaemia and acute parvovirus B19 infection. A skin biopsy confirmed extensive necrotising vasculitis with intravascular thrombi, affecting the dermal and subcutaneous vessels. Eculizumab, corticosteroid and intravenous immunoglobulin were given, and within 24\u00a0h, symptoms markedly improved. The patient later developed breakthrough haemolysis in the setting of varicella zoster virus infection, which responded well to additional anti\u2010complement therapy. This case demonstrates that viral infections can precipitate acute thrombosis and severe haemolysis in PNH patients and that a combined treatment approach confers good recovery.<\/jats:p>\n
