title: [An anomaly in Poland. A description of a clinical case of a three years and four months-old boy].
abstract: The authors describe Poland's anomaly in a boy aged three years and four months, characterised by a depression in the right hemithorax caused by the absence of the medial extremity of the large pectoral muscle with hypoplasia of the remaining venter musculi. Moreover, the scan showed the absence of the small homolateral pectoral muscle. The vascular alteration of the subclavian artery and/or its branches during embryogenesis might be related, in this case, to the fact that the mother took sex hormones during the 6th and 7th week of gestation.
