Pearson Syndrome, A Medical Diagnosis Difficult to Sustain Without Genetic Testing
The detection of sideroblastic anemia in a newborn may suggest developing Pearson syndrome. The prognosis of these patients is severe and death occurs in the first 3 years of life, so it is important to find new ways of diagnosis. Case Presentation: In the case of our patient the diagnosis was supported only at the age of 5 months, highlighting the difficulties of diagnosis at this age. The diagnosis of Pearson syndrome with neonatal onset is difficult to sustain or even impossible at that age. This diagnosis can be confirmed and supported during disease progression.
