Dermatitis repens

Overview

Dermatitis repens, also known as acrodynia or acrodynic eczema, is a rare and chronic skin condition characterized by the progressive peeling and shedding of the skin, primarily affecting the hands and feet. This condition is often associated with autoimmune disorders and can be triggered by various factors, including allergens, infections, and stress.

Clinical Presentation

The hallmark of dermatitis repens is the appearance of erythematous, scaly patches that gradually evolve into areas of peeling skin. Patients may experience intense pruritus (itching), erythema (redness), and edema (swelling) in the affected regions. The condition can lead to significant discomfort and may interfere with daily activities due to the sensitivity and pain associated with the lesions.

Pathophysiology

The exact pathophysiology of dermatitis repens is not fully understood, but it is believed to involve an abnormal immune response that leads to inflammation and subsequent skin damage. The condition may be linked to genetic predispositions and environmental triggers that activate the immune system, resulting in the characteristic skin changes.

Diagnosis

Diagnosis of dermatitis repens is primarily clinical, based on the appearance of the skin lesions and the patient's history. A thorough dermatological examination is essential, and in some cases, a skin biopsy may be performed to rule out other conditions such as psoriasis or eczema.

Treatment

Management of dermatitis repens involves a combination of topical and systemic therapies aimed at reducing inflammation and alleviating symptoms. Topical corticosteroids are commonly used to decrease inflammation, while emollients help to maintain skin hydration. In more severe cases, systemic treatments such as immunosuppressants or biologic agents may be considered.

Prognosis

The prognosis for dermatitis repens varies depending on the severity of the condition and the patient's response to treatment. While some individuals may experience periods of remission, others may have chronic symptoms that require ongoing management. Early intervention and adherence to treatment regimens can improve outcomes and enhance the quality of life for affected individuals.
