Poland's syndrome and breast cancer: coincidence or not?

Poland's syndrome is an uncommon congenital anomaly of unknown etiology, the main characteristic of which is the absence of the major pectoral muscle. Thorax and upper limb malformations also may be present. Poland's syndrome has been observed in clinical cases connected to a variety of neoplasia, primarily hematological disorders. Patients with Poland's syndrome who have developed breast cancer have been reported incidentally. Here we report a case of Poland's syndrome associated with breast cancer.
