Quantify steatosis, fibrosis, and focuses of extramedullary erythropoiesis (ER) in the liver and report it to the causes of death in the perinatal. Morphologic analysis of steatosis', percentage of fibrosis, and ER of 467 perinatal autopsies. Cases with hypoxia/perinatal anoxia and ascending infection showed higher percentage of fibrosis. The number of ER was significantly higher among premature infants and in cases with infection. Our results contribute to a better quality of perinatal care through clinical demonstration of which injuries are associated with them, what may help in early diagnosis of these alterations in children who survive.
