The normal new-born infant has a high erythrocyte count with a correspondingly high content of hemoglobin. In the past ten years, there has appeared in the pediatric literature a small group of case reports of so-called primary anemia of the new-born. No satisfactory explanation of the pathogenesis has been offered. Such cases have been reported by Ecklin,1 Donnally,2 Susstrunk,3 Sanford4 (three cases), Sidbury,5 Canino,6 Bonar,7 Ehrmann,8 Happ,9 Gelston and Sappington,10 and Greenthal.11 In addition, Grulee12 mentioned having seen three or four cases; Foote13 had five cases, and McClelland14 had one case. In a recent monograph, Blackfan, Baty and Diamond15 briefly described a case and stated that they have the records of four cases as yet unpublished. In all, the occurrence of a total of twenty-eight cases has been reported in the literature.
