A Case of Sacroiliitis in Psoriasis with Behcet's Disease / 대한류마티스학회지

Psoriasis is a chronic inflammatory skin disorder, which is characterized by erythematous, sharply demarcated papules, and rounded plaques covered by silvery micaceous scale. Psoriatic arthritis is a heterogeneous disease with typical features of the spondyloarthropathies. Behcet's disease is an inflammatory condition involving multiple organ systems such as mucous membrane, skin, joint, intestine, lung, central nervous system, and vessel. The inclusion of Behcet's disease among seronegative spondyloarthropathies is still being debated. We described a 47-year-old female patient who currently had psoriasis and Behcet's disease. She developed a sacroiliitis that was probably precipitated by trauma.
