Summary
A rare juxtacortical bony lesion in a psoriatic arthritis patient mimicked osteosarcoma radiographically. Biopsy revealed florid inflammatory enthesopathy, highlighting diagnostic challenges in bone proliferative lesions.
Area of Science:
- Orthopedic Oncology
- Rheumatology
- Radiology
- Pathology
Background:
- Psoriatic arthritis can affect various joints, including the ankles and feet.
- Juxtacortical bony lesions require careful differentiation between neoplastic and inflammatory processes.
- Bicipital tendon insertion sites are susceptible to both reactive and neoplastic changes.
