Neoplasms of the nailbed

Neoplasms of the nailbed may often present with paronychia, ingrown nail, onycholysis, pyogenic granuloma, nail-plate dystrophy, longitudinal erythronychia, bleeding, and discolorations.^[1]: 792 There are various benign and malignant neoplasms that may occur in or overlying the nail matrix and in the nailbed, and symptoms may include pain, itching, and throbbing.^[1]: 792

Benign tumors of the nails include verruca, pyogenic granuloma, fibromas, nevus cell nevi, myxoid cysts, angiofibromas (Koenen tumors), and epidermoid cysts.^[1]: 792

Squamous cell carcinoma of the nailbed is uncommon, and often mistaken for a pyogenic granuloma initially.^[1]: 792 Subungual melanoma is frequently diagnosed late in the course of growth.^{[1]: 793 [2]}
