Pustular psoriasis

Pustular psoriasis is a limited epidermal cavity bulge containing cloudy pus. It originates from pimples and blisters on the skin. The size of the pustules varies in depth, and there may be inflammatory flushing around it. The shallow pustules become dry and do not leave scars after healing. Deeper pustules can form ulcers and scars after healing. Pustular psoriasis is a lesser type of psoriasis, accounting for about 0.69% of psoriasis. Clinically, it is usually divided into general pustular psoriasis and palmoplantar psoriasis. Pustular psoriasis is more common in young adults, often accompanied by sulcus tongue. The cause of the disease is not clear. Some people think that after taking corticosteroids for a long time in patients with normal psoriasis, the disease is easy to occur, or it is related to infection and drug stimulation.
