title: Anterior intercostobrachial nerve penetrating the pectoralis minor or major muscle.
abstract: Two previously unknown anomalies of the anterior intercostobrachial nerve were described. In one case, the anterior intercostobrachial nerve penetrated the pectoralis minor muscle. In the other case, it penetrated the pectoralis major muscle. In both cases, the anomalous nerve supplied the skin of the upper arm.
