Topic to discuss: Saddle Nose Deformity in a Patient with undifferentiated Spondylarthritis: A Diagnostic Challenge
Learnings/Clinical Pearls:
Explain that while undifferentiated Spondylarthritis is a chronic inflammatory arthritis, a saddle nose deformity is not a feature of this and suggests another process. The aim is to explore the differential diagnosis, with a focus on cocaine‑induced midline destructive lesions (CIMDL) and vasculitis.
