Poland's syndrome; case report.

Syndrome named after Sir Alfred Poland is described as an absence or under development of the chest muscle (pectoralis) on one side of the body as well as webbing of the fingers (cutaneous syndactyly) on the hand of the same side. Poland syndrome is usually sporadic, although rare familial cases have been described1. The incidence of Poland’s syndrome varies between groups (male versus female patients and congenital versus familial cases) and ranges from 1 in 7,000 to 1 in 100,000 live births2. The cause of Poland syndrome is unknown. However, an interruption of the embryonic blood supply to the arteries that lie under the collar bone (subclavian arteries) at about the 46th day of embryonic development is the prevailing theory3.
