Description
During a routine anatomy lab dissection, a group of first year medical students at Philadelphia College of Medicine (PCOM) South Georgia found an anatomic variant known as the sternalis muscle. This muscle was found bilateral and superficial to the left medial pectoral major muscle, with superior attachments to the sternum and inferior attachments to the left superior and lateral portion of the rectus abdominis. A past study found that 2% Caucasian, 8% African Americans, 11% Asian individuals had a sternalis muscle recorded as well as 8.7% women and 6.4% men of a 532 cadaver sample size (Bergman et al., 1992). Previous studies have shown that its presence can altered routine mammogram results which shows significance in misdiagnosis in breast cancer. 4
