Poikiloderma of Civatte

Poikiloderma of Civatte is a skin condition that primarily affects the neck and chest, characterized by redness, pigmentation, and skin atrophy. It was first described by the French dermatologist Achille Civatte in 1923. The condition is more common in middle-aged and elderly individuals, particularly those with fair skin.

Causes

The exact cause of Poikiloderma of Civatte is unknown, but it is believed to be associated with chronic sun exposure, hormonal changes, and aging. The condition is more common in individuals who have had significant exposure to the sun over their lifetime. It is also more common in women, suggesting a possible hormonal component.

Symptoms

The primary symptoms of Poikiloderma of Civatte are redness, pigmentation, and skin atrophy. The redness is due to dilation of the small blood vessels in the skin, known as telangiectasia. The pigmentation is due to an increase in melanin, the pigment that gives skin its color. The skin atrophy is due to a thinning of the skin, which can give it a wrinkled appearance.

Diagnosis

The diagnosis of Poikiloderma of Civatte is typically made based on the characteristic appearance of the skin. A dermatologist may use a Wood's lamp, which emits ultraviolet light, to help identify the changes in pigmentation. In some cases, a skin biopsy may be performed to rule out other conditions.

Treatment

There is no cure for Poikiloderma of Civatte, but treatments can help manage the symptoms. These may include topical creams to lighten the skin, laser treatments to reduce redness and pigmentation, and sun protection to prevent further damage. In some cases, surgery may be considered to remove areas of atrophy.
