Subungual hematoma refers to the accumulation of blood under the nail plate due to acute or chronic trauma to a fingernail or toenail. The injury results in the rupture of blood vessels in the nail bed, leading to the accumulation of blood between the nail bed and the nail plate [1]. Patients may experience pain or pressure in the affected area. Subungual hematomas grow out with nail plate growth (toenails 12–18 months, fingernails 6–9 months).
