Аннотация
BACKGROUND: Pearson syndrome is a rare mitochondrial disorder characterized by sideroblastic anemia, liver disease, renal tubulopathy and exocrine pancreas deficiency.
OBSERVATIONS: We describe a female infant suffering from anemia since birth who gradually developed the complete picture of Pearson syndrome by 13 months. Iron overload was disproportionate to blood transfusions. The patient was heterozygous for HFE gene C282Y mutation (type I hemochromatosis). After an initial response to deferoxamine she presented with cutaneous zygomycosis and died after metabolic derangement and Pneumocystis jiroveci pneumonia.
CONCLUSION: This is the second case of a Pearson syndrome individual who was also heterozygous for HFE gene mutation C282Y published. It is also the second case report of a Pearson patient suffering from severe iron overload and liver disease that responded to therapy with deferoxamine.
