Erythema <em>ab igne</em> masking cutaneous metastasis of colorectal adenocarcinoma

Abstract

Skin metastasis commonly manifest as subcutaneous or intradermal violaceous nodules that coalesce with a firm rubbery appearance. Few cases reported an erythema ab igne-like appearance in the presence of internal malignancy. We report a case of metastatic colorectal adenocarcinoma with erythema ab igne-like presentation. We also review cases of erythema ab igne in association with internal malignancy.
