Which condition is characterized by palpable edema at the costochondral junction?

• A. Costochondritis
• B. Rib fracture
• C. Pneumothorax
• D. Tietze syndrome

Answer: (D)

Palpable edema at the costochondral junction points to swelling of the costal cartilage area, which is the distinguishing feature of Tietze syndrome. This condition presents with chest wall pain concurrent with a tender, swollen costochondral junction—often at the second or third joints. In contrast, costochondritis causes similar chest wall pain without visible or palpable swelling. A rib fracture would follow trauma and show focal tenderness or deformity, not just edema at a joint. Pneumothorax brings acute respiratory symptoms and signs of lung collapse rather than localized edema at the chest wall junction.
