A case of Poland's syndrome in a newborn is described. The syndrome is relatively unknown, especially in its epidemiological and aetiopathogenetic aspects. It's characterized by aplasia of the sternal head of the pectoral major muscle, hypoplasia of the upper extremities and homolateral aplasia of II, III, IV, V finger. Attention is drawn to the importance of reporting diagnosed cases in order to further our knowledge of the syndrome. The Authors are looking with a big interest the correlation between hair treatment and Poland's anomaly.
