CARCINOMA of the breast can produce cutaneous metastases which show a highly diversified clinical picture.1 Consequently, many descriptive terminologies have been used, especially before the etiology and pathology of the lesions were known or understood.
Probably the most common type of metastatic cutaneous carcinoma from the breast is inflammatory carcinoma. According to Lee and Tannenbaum2 who have reported 28 cases, this particular type occurs in 1.3% of all mammary cancers. Clinically, the skin over and around the breast is red, warm, and slightly brawny, with well-demarcated borders similar to erysipelas. There is usually no ulceration. Pathologically, the dermal lymphatics are invaded by malignant tumor cells, and there is an associated hyperemia and inflammation of the corium. The primary breast tumor can be any histologic type of carcinoma. Other authors have reported similar cases but have used slightly different names. Volkman and Billroth3 spoke of mastitis carcinomatosa. Rodman4
