A Case of Poland Syndrome Diagnosed by Prenatal Ultrasonography / 대한산부인과학회지

ABSTRACT

Poland syndrome is a rare congenital disorder. It is characterized by unilateral chest wall hypoplasia, ipsilateral arm and hand abnormalities, and a variety of associated anomalies. It is suggested that the deformity has a sporadic and nongenetic nature. The main pathogenetic mechanism is the interruption of embryological blood supply to the subclavian artery with hypoplasia at the end of the 6th week of gestation. Most frequently involved muscle is the sternocostal portion of the pectoralis major muscle, with hypoplasia of breast and nipple, rib anomalies and unilateral brachysyndactyly. We experienced an unusual case of Poland syndrome which was detected by prenatally ultrasonographic evaluation at 36 gestational weeks. So, we report this case with a brief review of the literature.
