Porotic hyperostosis and cribra orbitalia: the erythropoietic response to iron-deficiency anaemia

recent paper by Walker et al. (2009) states that iron-deficiency anaemia can no longer be regarded as being a cause of porotic hyperostosis (PH) or cribra orbitalia (CO). It is argued here that this conclusion is not supported by the current literature on iron-deficiency anaemia and associated haematopoietic responses or consequences to this condition. Indeed, iron-deficiency anaemia is still a plausible candidate in any differential diagnosis of lesions identified as PH and/or CO.
