Lupus cutané subaigu et cancer : deux cas et revue de la littérature

The diagnosis of subacute cutaneous lupus erythematosus was supported in our two patients by the presence of an annular photo-distributed eruption associated with positive testing for anti-Ro/SSA antibodies. Occurrence of the eruption in both cases with relapse of the neoplasia and its improvement after oncological treatment reinforced the diagnosis of paraneoplastic syndrome in one case, and the use of chemotherapy known to trigger lupus could have suggested a diagnosis of drug-induced subacute cutaneous lupus erythematosus. Thus, the association between lupus and cancer is relevant.
