“…Recent reports have highlighted the protean clinical presentations of HES, including watershed cerebral infarction (McMillan et al , 2008), with sarcoma and granulocyte macrophage‐colony stimulating factor (GM‐CSF) production (Ando et al , 2007), orbital pseudotumour (Zenone & Ligeon‐Ligeonnet, 2005), retro‐orbital mass (Vigna et al , 2008), Budd Chiari syndrome (Becker et al , 2006; Inoue et al , 2007), erythroderma (Granjo et al , 2002; Lee et al , 2007), thrombosis of the cerebral superior sagital sinus (Sakuta et al , 2007), Kimura disease (Barge et al , 2008), Buerger disease (Kawata et al , 2007), lymphoma (Bae et al , 2007; Capovilla et al , 2008), with haemolytic anaemia and eosinophil erythrophagocytosis (Kuk et al , 2006), during pregnancy (Ogasa et al , 2006; Ault et al , 2009), with pemphigoid nodularis (von Felbert et al , 2006), with recurrent optic neuritis (Lincoff & Schlesinger, 2005), brachial artery occlusion (Ponsky et al , 2005), and, especially, with superficial venous thrombosis (Liao et al , 2005; Terrier et al , 2006; Sakuta et al , 2007). Mucosal ulcers of the mouth, genitalia and anus should alert the clinician to a particular variant, myeloproliferative HES (Leiferman et al , 1982; Leiferman & Gleich, 2004).…”
