title: Pseudotumoral articular amyloidosis.
abstract: We present a 71-year-old man with primary amyloidosis characterized by several outstanding clinical features, namely hip involvement of a pseudotumoral appearance, periarticular osteolytic lesions and a pathological fracture. Kappa light chains in the synovial fluid were observed. The patient survived for 90 months without developing plasma cell dyscrasia, and with preservation of vital functions despite parenchymal involvement of multiple organs.
