A 30-year-old woman was referred with right breast pain and tenderness of recent onset with a likely diagnosis of inflammatory breast carcinoma. Eleven years ago she had developed the cutaneous lesions of the hands, forehead, cheeks, and ears that often accompany discoid lupus erythematosus; these lesions were treated with hydroxychloroquine, topical betamethasone cream, and thalidomide. Within the last 12 months, she developed multiple inflammatory episodes of the right breast while receiving hydroxychloroquine; she was treated with prednisolone because of a presumptive diagnosis of lupus mastitis.
