Infiammatory carcinoma or carcinoma erysipeloides is a well-recognized, although uncommon, cutaneous manifestation of metastatic malignancy, accounting for 4% of skin metastases. It is most frequently associated with carcinoma of the breast, but has been reported with other primary tumours, including lung and colon.
Malignant melanoma presenting as an inflammatory skin metastasis has been described but is an exceedingly rare phenomenon. We report a case of inflammatory metastasis of cutaneous melanoma (CM).
