[Idiopathic adult pulmonary hemosiderosis: a new etiopathogenetic hypothesis].

IPH is an uncommon disease affecting mainly children and adults and has usually a poor prognosis. The basic pathogenesis of the disorder is unknown; many theories have been advanced, but none is proved. A case of IPH in a 35 years old male presenting the atypical feature of a myeloperoxidase deficiency is reported. This unusual feature may be compatible with a generalized redox systems deficiency, which leads, via an impaired flow of iron into alveolar macrophages, to the pulmonary fibrosis.

Hemosiderosis without cirrhosis: an unusual case of portal hypertension.

A renal transplant recipient presented with bleeding esophageal varices. Needle biopsy, later confirmed by operative wedge biopsy, showed slight periportal fibrosis but no cirrhosis or hepatitis. No etiology for his liver disease could be determined and he could not be differentiated from other reported patients with idiopathic noncirrhotic portal hypertension (IPH). His liver biopsy did show massive hepatic iron deposition. He had received about 115 units of blood while on hemodialysis and had taken oral iron supplementation for 8 years. IPH has been associated with toxin exposure, especially arsenic and vinyl chloride. This case suggests that excessive iron deposition may also lead to IPH and the indiscriminate use of iron supplementation in hemodialysis or renal transplant patients should be avoided.
