Axillary lymph node and early breast cancer diagnostics. A case report.

Understanding of the anatomy of the axillary lymph nodes is important in diagnostic and treatment procedures for breast cancer. An interesting case is presented here of breast cancer without a breast tumour. The first symptom of the disease was lymphadenopathy of the axillary region. This kind of case is extremely rare in clinical practise (one case per 1-5 years) and constitutes a great problem for specialists, since in many cases the primary neoplasm source is unknown. The anatomical and clinical implications of such a situation are discussed.
