Poikiloderma (pronounced: poy-ki-lo-der-ma) is a skin condition that involves changes in the skin's color, atrophy, and telangiectasia.
Etymology
The term "poikiloderma" is derived from the Greek words "poikilos" meaning varied and "derma" meaning skin.
Definition
Poikiloderma is a cutaneous condition characterized by a specific pattern of changes in the skin's color (hyperpigmentation and hypopigmentation), thinning of the skin (atrophy), and dilation of the small blood vessels (telangiectasia).
Symptoms
The symptoms of poikiloderma can vary but often include:
- Hyperpigmentation: Darkening of the skin
- Hypopigmentation: Lightening of the skin
- Atrophy: Thinning of the skin
- Telangiectasia: Dilation of the small blood vessels
Causes
Poikiloderma can be caused by a variety of factors, including:
- Genetic disorders: Certain genetic disorders, such as Rothmund-Thomson syndrome, can cause poikiloderma.
- Sun exposure: Chronic sun exposure can lead to poikiloderma, particularly in individuals with fair skin.
- Dermatological diseases: Certain skin diseases, such as cutaneous T-cell lymphoma, can cause poikiloderma.
Treatment
Treatment for poikiloderma often involves addressing the underlying cause of the condition. This may include:
- Sun protection: Protecting the skin from the sun can help prevent further skin damage.
- Topical treatments: Topical creams and ointments can help improve the appearance of the skin.
