It can be seen with signs of inflammation such as pain, swelling, redness, as well as different symptoms and findings like sensory and motor dysfunctions and trophic changes. Therefore, it should be included in the differential diagnosis of painful conditions of the upper extremities. We report two cases of patients with CRPS type I with unknown etiologies who were misdiagnosed as inflammatory arthritis and also discussed in view of the literature.
