Pseudoxanthoma-elasticum-like syndrome and thalassemia: an update.

Pseudoxanthoma Elasticum (PXE) is an autosomal recessive, multisystem disorder affecting connective tissues. We describe three cases of the acquired PXE-like syndrome that often occurs in association with hemolytic anemias, in particular the hemoglobinopathies, and review the literature on the subject. The pathogenesis of the acquired PXE-like lesions is not yet completely understood. None of the mutations observed in the inherited form has been detected in the syndrome accompanying thalassemia. The cardiovascular complications could be life-threatening. Therefore, an close surveillance of these patients is mandatory.
