[Migrant eruptions in lupus erythematosus. Apropos of a case of lupus erythematosis gyratus repens].

Rare cases of migrant circinated eruptions occurring during the course of lupus erythematosus have been published so far. They have been classified in two categories: 1) supposed toxicodermias due to antimalarials; 2) real cases of erythema annulare centrifugum, mostly inaugurating the L. E. In an exceptional case, a migrating eruption looking like an erythema annulare with a complicated pattern on the trunk, neck and limbs, took place between two rashes of typical L.E. The exact nature of this eruption, clinically and histologically atypical, and its relation with the L.E. itself, have been discussed.
