Zirconium granulomas are a skin condition characterized by a papular eruption involving the axillae, and are sometimes considered an allergic reaction to deodorant containing zirconium lactate.[1]:46

Yellow nail syndrome (also known as “Primary lymphedema associated with yellow nails and pleural effusion”[1]:849) is a very rare medical syndrome that includes pleural effusions, lymphoedema and yellow dystrophic nails. Approximately 40% will also have bronchiectasis. It is also associated with chronic sinusitis and persistent coughing. It usually affects adults.[2][3]:665

Normal treatment for swelling and any respiratory problems is appropriate. Nutritional supplementation with Vitamin E in some studies has been shown to be effective in controlling nail changes.[2]

Restated, yellow nail syndrome is characterized by marked thickening and yellow to yellow-green discoloration of the nails often associated with systemic disease, most commonly lymphedema and compromised respiration.[1]:792

One way to treat xerotic eczema is to avoid scratching the affected area and to apply anti-itch or moisturizing lotion frequently.

A study published in 2005 found positive results when the affected area was soaked in water for twenty minutes and subsequently applying mid- to high-strength corticosteroid ointment.[2]

Xerotic eczema (also known as “Eczema craquelé,” “Pruritus hiemalis,” “Asteatotic eczema,” and “Winter itch”[1]:81) is a form of eczema that is characterized by changes that occur when skin becomes abnormally dry, itchy, and cracked. Lower legs tend to be especially affected, although it can appear in the underarm area as well.[citation needed]

Xerotic eczema is common in elderly people, though it is not uncommon for people in their 20s. It can appear in red, bumpy, pimple-like irritations. Shaving can cause it to become inflamed.[citation needed]

Xeroderma is a very common condition. It happens more often in the winter where the cold air outside and the hot air inside creates a low relative humidity. This causes the skin to lose moisture and it may crack and peel. Bathing or showering too frequently, especially if one is using harsh soaps, may also contribute to xeroderma. Xeroderma can also be caused by a deficiency of vitamin A, vitamin D, systemic illness, extreme overexposure to sunlight (sunburn), extreme underexposure to sunlight, or some medication.[citation needed]

Xeroderma (literally “dry skin”) is a condition involving the integumentary system, which in most cases can safely be treated with emollients and/or moisturizers. Xeroderma occurs most commonly on the scalp, lower legs, arms, the knuckles, the sides of the abdomen and thighs. Symptoms most associated with xeroderma are scaling (the visible peeling of the outer skin layer), itching and cracks in the skin.

Xanthoma disseminatum (also known as “Montgomery syndrome”) is a rare cutaneous condition that preferentially affects males in childhood, characterized by the insidious onset of small, yellow-red to brown papules and nodules that are discrete and disseminated.[1]:717

X-type histiocytoses are a clinically well-defined group of cutaneous syndromes characterized by infiltrates of Langerhans cells, as opposed to Non-X histiocytosis in which the infiltrates contain monocytes/macrophages.[1]:720 Conditions included in this group are:[1]:720-4
Congenital self-healing reticulohistiocytosis
Langerhans cell histiocytosis

X-linked recessive chondrodysplasia punctata is a type of chondrodysplasia punctata that can involve the skin, hair, and cause short stature with skeletal abnormalities, cataracts, and deafness.[1]:500

It has been associated with arylsulfatase E.[2]

Wooly hair nevus is a nonhereditary focal skin condition that usually appears within the first 2 years of life, but with can occur as late as adolescence.[1]:647
