Atrophoderma

Overview

Atrophoderma on the hands

Atrophoderma is a term used to describe a group of skin conditions characterized by localized or diffuse thinning of the skin. This condition can result from a variety of causes, including genetic factors, inflammatory processes, or the use of certain medications such as corticosteroids.

Etiology

Atrophoderma can be classified based on its underlying cause:

• Atrophoderma of Pasini and Pierini: A form of atrophoderma that presents as hyperpigmented, depressed patches on the skin, often on the trunk.
• Steroid-induced atrophy: Prolonged use of topical or systemic corticosteroids can lead to thinning of the skin, known as steroid atrophy.
• Anetoderma: Characterized by localized areas of slack skin due to loss of elastic tissue.

Clinical Presentation

The clinical features of atrophoderma vary depending on the specific type and cause. Common features include:

• Thinning of the skin
• Depressed or indented patches
• Changes in skin pigmentation

Diagnosis

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

Management

Management of atrophoderma depends on the underlying cause. For steroid-induced atrophy, discontinuation or reduction of corticosteroid use is recommended. Other treatments may include:

• Topical retinoids
• Laser therapy
• Phototherapy

Prognosis

The prognosis for atrophoderma varies. Some forms, such as steroid-induced atrophy, may improve with treatment, while others may persist or progress.
