📌 Extracapsular Tophi

Extracapsular tophi typically affect the prepatellar bursae and extensor mechanism, leading to several characteristic changes:

• Anterior soft-tissue prominence
• Bursal distention
• Tendon enlargement due to intratendinous urate deposition
• Well-marginated erosions at the patella and tibial tuberosity

 

📌 Subcutaneous or Extra-Articular Tophi

• Subcutaneous or extra-articular tophi are usually a late manifestation and often occur together with intra-articular tophaceous deposition. 
• Extra-articular tophi are relatively rarer than intra-articular tophi, and in most patients, extra-articular tophi are associated with intra-articular lesions.
