Poland sequence: two unusual cases and brief review of the literature.

Poland Sequence consists of a congenital absence of the pectoralis major muscle. Classically, the sequence also includes ipsilateral hand anomalies. Identified patients may be screened for renal and other anomalies. The condition results in physical and cosmetic disabilities which can be treated if properly triaged. The chest wall anatomy may be delineated with computed tomography and MRI if surgery is planned. Two cases with unusual findings including lumbosacral spine malformation and contralateral hand syndactyly are presented.
