Inflammatory Cutaneous Metastases from Cloacogenic Carcinoma of the Anus

BACKGROUND There are a few tumors that exhibit inflammatory cutaneous metastases. This pattern is particularly difficult to diagnose since it can mimic erysipelas or lymphangitis. OBJECTIVE This is a presentation of a 69‐year‐old woman diagnosed with poorly differentiated cloacogenic carcinoma who simultaneously was noted to have an abdominal rash. A biopsy confirmed cutaneous metastasis of her carcinoma. METHODS Previously published literature on cutaneous metastases were reviewed and summarized. RESULTS This is the first reported case of an inflammatory cutaneous metastasis arising from cloacogenic carcinoma. CONCLUSION Cutaneous metastases can present in various forms, including the inflammatory pattern. Because this form mimics other conditions, it is prudent to biopsy any suspicious skin lesion in cancer patients, as it may considerably affect prognosis.
