CARCINOMA en cuirasse is the term generally applied to extensive infiltrating plaques resulting from cutaneous metastasis from cancer in other organs of the body. These plaques are usually formed from the coalescence of hard carcinomatous nodules, but at other times pronounced inflammatory reaction is seen, so that many cases have been referred to as carcinoma erysipelotoides. In 1938 Taylor and Meltzer1 described 38 cases of this inflammatory type of metastasis, all arising from the breast and involving the skin of the chest. Later, in 1941, Reuter and Nomland2 published a report of a similar case involving the face and neck but with the primary growth in the rectum.
The following case is another example of the inflammatory type of cancer en cuirasse arising from a visceral primary growth.
