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.
They appear as thickened, fissured cauliflower-like skin around the nail plate. Periungual warts often cause loss of the cuticle and paronychia. Nail biting increases susceptibility to these warts. [1] Warts of this kind often cause damage to the nail either by lifting the nail from the skin or causing the nail to partially detach.
The nails are markedly thickened with yellow to yellow-green discoloration of the nails. [1]: 792 [6] They grow slowly, at a rate of 0.25 mm/week or less. The nails may have ridges and increased side-to-side curvature, reduction of the white crescent and detachment of the nail from the nailbed. [5] These nail abnormalities may also change over ...
Onychomycosis, also known as tinea unguium, [4] is a fungal infection of the nail. [2] Symptoms may include white or yellow nail discoloration, thickening of the nail, and separation of the nail from the nail bed. [2]
Psoriatic nails are characterized by a translucent discolouration in the nail bed that resembles a drop of oil beneath the nail plate. [2] Early signs that may accompany the "oil drop" include thickening of the lateral edges of the nail bed with or without resultant flattening or concavity of the nail; separation of the nail from the underlying nail bed, often in thin streaks from the tip-edge ...
Onychodystrophy is a deformation of the nails that can result from cancer chemotherapy which includes bleomycin, hydroxyurea, or 5-fluorouracil. It can include discoloration of the nail, or dyschromia. Onychogryposis, also called "ram's-horn nail", is a thickening and increase in curvature of the nail. It is usually the result of injury to the ...
Cleaning under the nail is not recommended as this only serves to separate the nail further. Bandages are also to be avoided. [11] When kept dry and away from further trauma, the nail will reattach from the base upward (i.e., from proximal to distal). The aim of treatment is also to eliminate onychomycosis that is a major cause of onycholysis.
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] The nail plate may also become thicker and more brittle as a result of the injury ...
