Objective:
To discuss the presentation and diagnosis of tophi in atypical locations in patients with chronic gout.
Approach:
Key Findings:
- Tophi typically occur in cooler sites but palmar and plantar involvement is rare.
- Plantar tophi may mimic warts or calluses, while palmar tophi may resemble calcinosis cutis or other nodular lesions.
- Accurate diagnosis is critical to avoid misdiagnosis as infection or malignancy.
Interpretation:
Tophi formation in atypical locations can complicate diagnosis and management in chronic gout patients.
Limitations:
- The rarity of palmar and plantar tophi may lead to delayed diagnosis.
- Misdiagnosis can result in unnecessary procedures.
Conclusion:
Accurate identification of tophi in atypical locations is essential for appropriate management of chronic gout.
