L40: Psoriasis

L40.3: Pustulosis palmaris et plantaris

Your body’s own immune system plays a role in the development of psoriasis. The condition can be hereditary. Other family members may then be affected, too. Triggers such as skin irritations, stress or certain medications can make the condition worse.

A lot of small, pus-filled pustules have formed on the skin in the palms of your hands and on the soles of your feet. The affected areas usually have a yellow or brown color. The nails may also change.
