title: Mycobacterium xenopi arthritis.
abstract: Osteoarticular Mycobacterium xenopi infections are very rare. We describe a patient with dermatomyositis and isolated shoulder arthritis due to M. xenopi. The diagnosis was delayed for 7 months; only 2 of 5 interval joint aspirates grew M. xenopi. The infection responded well to triple antituberculous therapy.
