Clinical features of malignant melanoma of the finger and therapeutic efficacies of different treatments

Recent advancements in the diagnosis and treatment of acral melanoma

Acral melanoma (AM) is the most common histologic subtype of melanoma in dark-skinned patients and is associated with a worse prognosis and a high mortality rate, largely due to the inconspicuous nature of early-stage lesions, which can lead to late diagnosis. Because of the overlapping clinical and histopathological features of AM with other forms of cutaneous melanomas, early detection of AM requires a multidisciplinary approach that integrates various diagnostic modalities, including clinical examination, dermoscopy, histopathology, molecular testing, radiological imaging, and blood tests. While surgery is the preferred method of treatment for AM, other therapeutic options may be employed based on the stage and underlying etiology of the disease. Immune checkpoint inhibitors, molecular targeted therapy, radiotherapy, chemotherapy, and oncolytic virotherapy represent promising advanced treatment options for AM. In this review, we provide an overview of the latest advancements in diagnostic and therapeutic methods for AM, highlighting the importance of early detection and the prompt, individualized management of this challenging disease.

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.
