Onychorrhexis (from the Greek words ὄνυχο- ónycho-, "nail" and ῥῆξις rhexis, "bursting"), is a brittleness with breakage of finger or toenails that may result from hypothyroidism, anemia, anorexia nervosa or bulimia, or after oral retinoid therapy. [1]: 786 It can also be seen in melanoma that involves the nail and onychomycosis. [2]
A new nail plate will form once the cause of the disease is removed. Onychomycosis, also known as tinea unguium, is a contagious infection of the nail caused by the same fungal organisms which cause ringworm of the skin (Trichophyton rubrum or T. mentagrophytes, rarely other trichophyton species or Epidermophyton floccosum [1]).
Causes [ edit ] Growing older or having poor biomechanics , which are more common in the elderly (e.g., toes that overlap and underlap; incompatibility between the foot and the shoe; or digiti flexi, which is characterized by contracted toes due to toe buckling caused by shortening of the controlling muscles), may be contributing factors.
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 ...
Causes may include: Shoes causing a bunching of the toes in the developmental stages of the foot (frequently in people under 21), which can cause the nail to curl and dig into the skin. This is particularly the case in ill-fitting shoes that are too narrow or too short, but any toed shoes may cause an ingrown nail.
Flexural: on the front of the fingers; Extensor: on the back of the fingers; Intertriginous: in an area where two skin areas may touch or rub together; Morbilliform: resembling measles; Palmoplantar: on the palm of the hand or bottom of the foot; Periorificial: around an orifice such as the mouth; Periungual/subungual: around or under a ...
Nail fungus can be painful and cause permanent damage to nails. It may lead to other serious infections if the immune system is suppressed due to medication, diabetes or other conditions. The risk is most serious for people with diabetes and with immune systems weakened by leukemia or AIDS, or medication after organ transplant.
It may cause thickening of the nails with areas of pitting, ridges, irregular contour, and even raising of the nail from the nail bed. [16] Squamous-cell carcinoma is mainly cancer of the skin, but can also affect the nail bed. It is a rare malignant subungual tumor subject to misdiagnosis as chronic paronychia. [16]
