During our routine dissection we noted a case of complete absence of pectoralis major with compensatory hypertrophy of pectoralis minor muscle and absence of medial pectoral nerve on the right side. Partial absence of pectoral muscles is not infrequent, however complete absence of pectoral major muscle is rare. There were no other associated anomalies. Though pectoralis major plays an important role in wide range of movements of shoulder joint, there is no significant loss in function of routine activities in case of absence of pectoralis major muscle because of compensation by surrounding muscles.
