A Nail Tumor is a lesion found under the nail plate. It is attached to the nail bed or matrix. Most tumor growths of the nail bed are benign, but some may be malignant.
These need to be removed surgically. Benign and malignant tumors both affect the nail and cause a deformity.
The tumors could be myxoid cysts, pyogenic granulomas, glomus tumors, onychocytic matricoma, Bowen disease or squamous cell carcinoma, and malignant melanoma.
