[Association of disseminated lupus erythematosus and Crohn's disease].
BACKGROUND
Association of Crohn's disease and systemic lupus erythematosus is infrequent. We report an observation of Crohn's disease that appeared in an 18-year-old woman followed-up for systemic lupus erythematosus for four years.


METHODS
The patient had all the clinical, biological and histological criteria of Crohn's disease and systemic lupus erythematosus was diagnosed according to the American Rheumatism Association criteria. On the base of this observation, we discuss the digestive manifestation of systemic lupus erythematosus and extradigestive manifestations of Crohn's disease.


CONCLUSIONS
The immunological background of both diseases was proposed to explain the mechanism of this rare association.
