Cancer en cuirasse is a widespread carcinomatous infiltration of the skin of the thoracicwaU, sometimes extending from the sternum anteriorly to the scapula posteriorly andeven covering the shoulders and extending down the upper arm. How much or how littledermal invasion justifies the use of the term is a matter of judgment, but it was theevident intention of the originators of the term that it should be reserved for casessufficiently widespread to suggest a breastplate, and not applied to ordinary cases inwhich the skin is infiltrated for a short distance Fig. -Cancer en cuirasse (recurrent), with lymphoedema of the Suitable case for METASTASIS Malignant disease is transferred to distant structures by conveyance of tumor cellswhich have become detached from the parent growth. Undoubtedly, the most importantavenue of dissemination in the early stages of carcinoma is furnished by the larger lym-phatic vessels which join the affected organ with its regional lymph nodes, and, howeverdistant the cancer cells may be in the later stages of the disease, it is to the lymph nodesadjacent to the primary growth that we must look for the first clinical evidence of metas-tasis in the great majority of instances. Thus, the axillary l3rmph nodes are the mostfrequently involved structures in the early stages of metastasis of cancer from the breast;indeed, complete freedom from such involvement is most exceptional in cases referredfor operation.
