A spectrum of inflammatory metastasis to skin via lymphatics: three cases of carcinoma erysipeloides.

We report a case in which carcinoma erysipeloides was the first sign of the primary malignancy in a patient with a rare form of prostate carcinoma (mixed adenosquamous type) and two cases in which carcinoma erysipeloides was a marker of tumor recurrence in two patients with breast carcinoma. The value of recognizing the distinctive inflammatory manifestation of carcinoma erysipeloides and the significance of dermal lymphatic involvement in this form of skin metastasis are discussed.
