Poikiloderma is a condition characterized by changes in the skin, including atrophy, telangiectasia, and variations in pigmentation such as hyperpigmentation and hypopigmentation. It is often a result of genetic disorders or environmental factors.

Signs and Symptoms

Poikiloderma presents with a combination of skin changes:

• Skin atrophy - thinning of the skin
• Telangiectasia - visible small blood vessels
• Hyperpigmentation - darkening of the skin
• Hypopigmentation - lightening of the skin

Causes

The causes of poikiloderma can be varied and include:

• Genetic disorders such as Rothmund-Thomson syndrome, Bloom syndrome, and Dyskeratosis congenita.
• Environmental factors like chronic sun exposure, which can lead to actinic damage.

Diagnosis

Diagnosis of poikiloderma is primarily clinical, based on the appearance of the skin. A biopsy may be performed to rule out other conditions and confirm the diagnosis.

Differential Diagnosis

Conditions that may present similarly to poikiloderma include:

• Lupus erythematosus
• Scleroderma
• Dermatomyositis

Treatment

Management of poikiloderma focuses on:

• Sun protection to prevent further damage
• Topical treatments such as retinoids or steroids to improve skin appearance
