title: Pustulotic arthro-osteitis associated with acetabular cartilage lesion in pustulotic arthropathy--implication of bone marrow.
abstract: We describe a case of pustulotic arthro-osteitis with hip joint involvement. After right hip joint and walking did not improve despite drugs and physical therapy, total hip replacement was performed. During surgery, brownish degenerated tissue was detected on the surface of the acetabular side. Pathohistological examination revealed that granulation tissue caused by suppurative inflammation of the bone marrow had broken through the cartilage surface, reaching the superficial layer. Our findings suggest that hip joint lesions in pustulotic arthro-osteitis may originate from bone marrow lesions.
