While crying, the left fourth intercostal space revealed a mass which herniated on expiration and receded on inspiration. On auscultation, the heart sounds were audible on the right side of the chest. Systemic examination was otherwise unremarkable. A roentgenogram of the chest revealed dextrocardia and hyperlucent left lung fields. Echocardiogram showed dextrocardia with a structurally normal heart. A clinical diagnosis of Poland's syndrome was made based on the hypoplasia of the left pectoral muscles, ribs and nipple, dextrocardia and lung herniation. He was thriving well when reviewed at 2\u2005years of age.<\/jats:p>","DOI":"10.1136\/bcr-2013-200106","type":"journal-article","created":{"date-parts":[[2013,8,6]],"date-time":"2013-08-06T08:18:59Z","timestamp":1375777139000},"page":"bcr2013200106","source":"Crossref","is-referenced-by-count":5,"title":["Lung herniation: an uncommon presentation of Poland's syndrome in a neonate at birth"],"prefix":"10.1136","volume":"2013","author":[{"given":"Suresh","family":"Chandran","sequence":"first","affiliation":[{"name":"Department of Neonatology, KK Women's and Children's Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krishna Gopagondanahalli","family":"Revanna","sequence":"additional","affiliation":[{"name":"Department of Neonatology, KK Women's and Children's Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dinesh","family":"Ari","sequence":"additional","affiliation":[{"name":"Department of Neonatology, KK Women's and Children's Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aftab Ahmed","family":"Rana","sequence":"additional","affiliation":[{"name":"Department of Neonatology, RIPAS Hospital, Brunei Darussalam"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,8,6]]},"reference":[{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.1","first-page":"191","article-title":"Deficiency of the pectoral muscles","volume":"2013","author":"Poland","year":"1841","journal-title":"Guy's Hosp Rep"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.2","doi-asserted-by":"crossref","first-page":"2218","DOI":"10.1016\/S0003-4975(02)04161-9","article-title":"Poland's syndrome revisited","volume":"2013","author":"Fokin","year":"2002","journal-title":"Ann Thorac Surg"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.3","first-page":"97","article-title":"Poland's syndrome: an incidental finding on routine medical examination","volume":"2013","author":"Hamidu","year":"2006","journal-title":"Nig J Surg"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.4","doi-asserted-by":"crossref","first-page":"903","DOI":"10.1002\/ajmg.1320230405","article-title":"Subclavian artery supply disruption sequence: hypothesis of a vascular etiology for Poland, Klippel-Feil, and Mobius anomalies","volume":"2013","author":"Bavinck","year":"1986","journal-title":"Am J Med Genet"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.5","doi-asserted-by":"crossref","first-page":"161","DOI":"10.1053\/j.sempedsurg.2008.03.005","article-title":"Poland's syndrome","volume":"2013","author":"Moir","year":"2008","journal-title":"Semin Pediatr Surg"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.6","doi-asserted-by":"crossref","first-page":"487","DOI":"10.1056\/NEJM197209072871004","article-title":"Nature and etiology of the Poland anomaly","volume":"2013","author":"David","year":"1972","journal-title":"N Engl J Med"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.7","first-page":"1177","article-title":"Dextrocardia in patients with Poland syndrome: phenotypic characterization provides insight into the pathogenesis","volume":"2013","author":"Torre","year":"2009","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.8","doi-asserted-by":"crossref","first-page":"760","DOI":"10.1016\/S0022-3468(89)80532-9","article-title":"Surgical treatment of thoracic deformity in Poland's syndrome","volume":"2013","author":"Shamberger","year":"1989","journal-title":"J Pediatr Surg"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.9","doi-asserted-by":"crossref","first-page":"760","DOI":"10.1016\/S0022-3468(89)80532-9","article-title":"Surgical treatment of thoracic deformity in Poland's syndrome","volume":"2013","author":"Shamberger","year":"1989","journal-title":"J Pediatr Surg"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.10","doi-asserted-by":"crossref","first-page":"194","DOI":"10.1002\/(SICI)1096-8628(19971212)73:2<194::AID-AJMG16>3.0.CO;2-L","article-title":"Poland sequence with dextrocardia: which comes first?","volume":"2013","author":"Fraser","year":"1997","journal-title":"Am J Med Genet"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.11","doi-asserted-by":"crossref","first-page":"1471","DOI":"10.1016\/j.jtcvs.2005.06.048","article-title":"Dextrocardia is a component of left-sided Poland syndrome","volume":"2013","author":"Eroglu","year":"2005","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2025082701570384000_2013.aug06_1.bcr2013200106.12","unstructured":"Ravitch MM .
