Introduction: Rheumatoid arthritis (RA) with a prevalence of 0.3 to 1% in the adult population is a chronic systemic inflammatory disease characterized by proliferative synovitis (pannus) leading to osteocartilaginous destruction leading to joint deformities [1]. The aim of this study is to show rheumatoid arthritis masked by sickle cell disease. Observation: This is a 38-year-old male, Soninke, 38-year-old female patient with known sickle cell disease who had consulted for polyarticular pain and lameness. In clinical and paraclinical studies, the diagnosis of rheumatoid arthritis was made in accordance with the ACR / EULAR 2010 criteria for sickle cell disease confirmed by hemoglobin electrophoresis. Conclusion: Rheumatoid arthritis is a common connective tissue disease in women. Its association with sickle cell disease is rare and can be a source of error or delay in diagnosis.
