[Differential Diagnosis of the Axillary Lymph Node]

The authors report on clinically abnormal palpatory findings in the axilla. The radiology and sonography of these findings is described, as well as differential diagnosis between normal findings and benign as well as malignant changes. If it is not possible to confirm a benign aspect even by means of examination via relevant equipment, histological clarification must be sought whenever there is a new palpatory finding or if changes are noted.
