Subungual melanoma describes a form of malignancy that develops in the cells under the fingernail or toenail. When carcinogenesis takes place in cells that contain skin pigments or melanocytes, it is called melanoma.
Diagnosis of subungual melanoma is made with a tissue biopsy, and there are several treatments to consider. Learn about these now.
Local Removal Of Affected Area
An individual may need local removal of the affected area if they are diagnosed with subungual melanoma. When subungual melanoma is in its early stages, it may be able to be excised without the need to have a full amputation of the fingertip or finger. This type of surgical procedure is referred to as a wide local excision. To even take a sample of tissue from a suspected subungual melanoma lesion, the entire nail plate must be removed. The amount of tissue that would need to be removed beneath that point would be determined on how deep the melanoma lesion or tumor penetrates the tissues. The margins of the tumor are determined by taking scrapings of the tissue and examining them under a microscope in real-time until the surgeon reaches the layer where no cancerous or abnormal cells are seen. Once the endpoint of the subungual melanoma is determined, the surgeon removes a nominal margin of tissue surrounding the area to ensure no cancerous cells are left behind.
