Subungual Melanoma with bone infiltration

Nail melanoma is rare and has a poor prognosis. It represents between 0.18 and 2.8% of all cutaneous melanomas. Amputation is usually performed for invasive nail melanoma, but not all invasive melanomas invade or attach to the distal phalanx. Our aim was to report a case of 56-year-old patient with history of a manipulated melanonychial band of the right big toe since 5 years presenting a nail melanoma with bone infiltration .Our patient illustrates the consequences of the late diagnosis of nail melanoma which led to a deep progression and the invasion of bone by the malignant melanocytes.
