A Rare Disease Presentation of Malignant Fungating Acral Melanoma of the Hand

Malignant melanoma is relatively uncommon and accounts for 1%–3% of all malignant tumors. Malignant melanoma of the hand is exceptionally rare and highly malignant, with rapid progression if left untreated. Early clinical symptoms can be overlooked, and the tumor is often at a late stage when patients seek care, prompting amputation of the affected region. We present a case of a 48-year-old man who presented with a rapidly progressive, large, fungating mass of the distal aspect of the little finger diagnosed as malignant melanoma. We describe the presentation and treatment of this patient, who ultimately underwent partial amputation of the fifth metacarpal. Histologic analysis demonstrated nodular melanoma.
