Inflammatory carcinoma masquerading as erythema annulare centrifugum.
Reichel M, Wheeland RG.
A case of inflammatory carcinoma, or carcinoma erysipelatodes, clinically resembling erythema annulare centrifugum is reported. The cutaneous inflammatory carcinoma was due to metastasis by a signet-ring cell adenocarcinoma, probably of gastrointestinal origin. This is the third reported case of inflammatory carcinoma with signet-ring cell infiltration. Cancer patients with atypical or unusual inflammatory dermatoses should be evaluated by skin biopsy because of the possible association with the internal neoplastic process.
