Summary
This study details a rare case of primary amyloidosis in a 71-year-old man, highlighting unusual hip joint and bone lesions. The patient achieved long-term survival despite widespread organ involvement.
Area of Science:
- Rheumatology
- Nephrology
- Hematology
Background:
- Primary amyloidosis is a rare plasma cell disorder.
- It can present with diverse and sometimes atypical clinical manifestations.
Observation:
- A 71-year-old male presented with pseudotumoral hip mass, periarticular osteolytic lesions, and pathological fracture.
- Synovial fluid analysis revealed kappa light chains, indicative of immunoglobulin deposition.
Findings:
- The patient exhibited a unique presentation of primary amyloidosis with significant skeletal involvement.
- Diagnosis was confirmed by detection of kappa light chains in synovial fluid.
Implications:
- This case expands the understanding of skeletal manifestations in primary amyloidosis.
- It underscores the importance of considering amyloidosis in patients with unexplained osteolytic lesions and fractures.
- Long-term survival is possible even with extensive organ involvement.
