Pustular psoriasis is primarily observed in adults. It is described by white pustules, which are blisters of noninfectious pus, surrounded by red skin. This pus is consisted of white blood cells. It is neither an infection, nor is it contagious.  Certain areas of the body are the place where it may be localized, the hands and feet for example. This type of psoriasis can also be generalized i.e. covering most of the body. Before the formation of pustules and scaling, pustular psoriasis tends to go in a cycle-reddening of the skin.

Pustular Psoriasis Triggers:

This form of psoriasis reportedly may be triggered by:

• Internal medications

• Irritating topical agents

• Overexposure to UV light

• Pregnancy

• Systemic Steroids

• Infections

• Emotional stress

• Sudden withdrawal of systemic medications

• Potent topical steroids

Combining or rotating treatments for pustular psoriasis is not unusual as the possibility for potential side effect of systemic medications and phototherapy is great.

Soriatane also known by its generic name acitretin and methotrexate in combination produced a rapid remission in the acute state of pustular psoriasis and an eventual clearing of the skin in more than one study.

Pustular Psoriasis Types:

They are:

Acropustulosis (accrodermatitis continua of hallopeau)

This type of pustular psoriasis is defined by skin lesions on the ends of the fingers and sometimes on the toes. An injury to skin or infection occasionally starts the eruption. Deformity of the nails is produced by the lesions being disabling and painful.

Palmo-Plantar Pustulosis:

This type of pustular psoriasis causes pustules on the palms of the soles of the feet and palms of the hands. Multiple pencil eraser-sized pustules in fleshy areas of the hands and feet are visible in this form of pustular psoriasis.

Von Zumbusch:

This form of pustular psoriasis suddenly appears on the skin. Reddened skin is widespread and the skin becomes tender and painful. It take within a few hours that pustules are visible.
