Drug induced psoriasis.

Psoriasis is a chronic inflammatory skin disorder clinically characterized by erythematous, sharply demarcated papules and rounded plaques covered by silvery micaceous scale. While the exact causes of psoriasis have yet to be discovered, the immune system and genetics are known to play major roles in its development. Many external factors including infections, stress and medications may exacerbate psoriasis.

[What should we know about venous and arterial ulcers?].

Chronic venous insufficiency starts by promoting the case of events. This results in pathologic venous and tissue changes consequential to chronic venous insufficiency. In this article, chronic venous insufficiency is defined as an abnormal function of the venous system due to venous valvular incompetence with or without associated venous outflow obstruction, which may involve the superficial venous system, deep venous system, or both.
