Poland syndrome in a neonate: report of one case.

Poland syndrome is an infrequent disease that presents in newborn infants and features an incidence of about one in 7,000 to one in 100,000 live births. The clinical features include an absence of the costosternal portion of the pectoralis major muscle, hypoplasia and/or aplasia of the ipsilateral breast or nipple, hypoplasia of subcutaneous tissue, abnormalities of the rib cage and upper extremity anomalies. We present a male newborn suffering Poland syndrome who featured a depressed left chest wall with respiratory distress. Ultrasonography of the chest revealed the absence of a section of pectoralis major muscle over the left chest wall, although no abnormality was found over the ipsilateral upper extremity. The patient was regularly followed up and showed no limitation to the range of motion of the left upper extremity at the age of four months.
