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.
