Treatment: Treatment for this skin disease is difficult. Pruritus can be controlled with antihistamines and topical corticosteroids. Ultraviolet phototherapy has been used. The deeper-penetrating ultraviolet A (UVA) rays work best. This is often administered in the form of psoralen + UVA (PUVA) therapy. Systemic corticosteroids and nonsteroidal immunosuppressant therapy are the main treatment strategies for this disease. Progressive systemic sclerosis requires a multidisciplinary approach to achieve the best therapeutic results.
