title: Multiple subcutaneous xanthogranuloma at juxta-articular sites with bone cystic changes resembling rheumatoid arthritis: A case report.
abstract: Xanthogranuloma is a benign disease represented as histiocytosis with lipoid deposition which usually occurs in children, but rarely in adults. We report a case of an adult patient with multiple subcutaneous xanthogranuloma at juxta-articular sites with bone cystic changes, manifesting similar clinical profiles to rheumatoid arthritis. Although very rare, we should consider the possibility of xanthogranulomatosis in the diagnosis of rheumatoid arthritis, especially in atypical cases.
