Subungual hematomas typically heal without incident, though infection may occur. The pressure of the blood blister may cause separation of nail plate from the nail bed (onycholysis), but the nail should not be pulled off, as this can cause scarring of the nailbed and deformed nails. [3] Nail discolouration may last some months. [4]
Subungual hematoma occurs when trauma to the nail results in a collection of blood, or hematoma, under the nail. It may result from an acute injury or from repeated minor trauma such as running in undersized shoes. Acute subungual hematomas are quite painful, and are usually treated by releasing the blood by creating a small hole in the nail.
Dermatologist Lindsey Zubritsky is “begging” her 1.4 million TikTok followers to check their nails for a vertical line, which could indicate a subungual melanoma, a rare, but serious skin cancer.
Distal subungual onychomycosis is the most common form of tinea unguium [2] and is usually caused by Trichophyton rubrum, which invades the nail bed and the underside of the nail plate. White superficial onychomycosis (WSO) is caused by fungal invasion of the superficial layers of the nail plate to form "white islands" on the plate.
Onychauxis presents with thickened nails without deformity, and this simple thickening may be the result of trauma, acromegaly, Darier's disease, psoriasis, or pityriasis rubra pilaris, or, in some cases, hereditary. [1]: 783 [2] It may appear as loss of nail palate translucency, discoloration, and subungual hyperkeratosis.
Maria Sylvia shared on TikTok how she discovered that a streak on her thumbnail for 10 years turned into rare, subungual melanoma. She hopes to raise awareness.
The surgical approach is the removal of the offending part of the nail plate known as a wedge resection. [10] If the ingrown toenail recurs despite this treatment, destruction of the sides of the nail with chemicals or excision is done; this is known as a matrixectomy. [10]
