Syndrome arthrocutané associé à  une maladie de Crohn chez une adolescente

The dermatosis-arthritis syndrome can be associated with bowel bypass and with inflammatory bowel disease, more frequently with ulcerative colitis than with Crohn's disease. It consists in a vesiculopustular eruption, erythema nodosum, fever, arthritis and ocular manifestations. Histopathology bears a strong resemblance with Sweet's syndrome. Physiopathology implicates microbial proliferation, formation of immune complex against skin and activation and migration of neutrophils and increasing factors. The treatment is based on corticosteroids and non steroid anti-inflammatory drugs or dapsone.
