title: Multicentric reticulohistiocytosis with positive anticyclic citrullinated antibodies.
abstract: This is a case report of a woman with multicentric reticulohistiocytosis with positive anticyclic citrullinated antibodies. This patient had been misdiagnosed with rheumatoid arthritis for many years. Recently, she presented with symmetric distal interphalangeal joint destruction and papules along her nail beds. Her clinical presentation, laboratory data, radiographic and histologic findings were all consistent with multicentric reticulohistiocytosis, not rheumatoid arthritis. This is the first case report of a patient with multicentric reticulohistiocytosis that tested positive for anticyclic citrullinated antibodies.
