Subacute lupus erythematosus-like gyrate erythema. Report of a case associated with a breast cancer.

We present a case of an annular skin lesion in association with a breast cancer. For differential diagnosis we had to consider subacute cutaneous lupus erythematosus and the group of gyrate erythemas. Lupus band test and immune serology were negative. The parallel course of the erythema and the internal malignancy were striking.
