Verrucous carcinoma of the foot is a rare malignancy, and proper diagnosis can be delayed. Furthermore, misdiagnosis often results in delayed appropriate treatment. Herein, we present an unusual case of verrucous carcinoma of the fifth toe with bone invasion in a 63-year-old woman that was mistaken for a plantar wart for 3 years. The condition was treated by ray amputation. We emphasize the need for appropriate biopsy to achieve an accurate diagnosis.
