Palmoplantar Pustular Psoriasis

Palmoplantar pustular psoriasis is a type of localized pustular psoriasis limited to the palms and soles. It is a chronic, recurrent eruption and can be very resistant to treatment.

Palmoplantar psoriasis is also known as palmoplantar pustulosis. Sometimes it is associated with psoriatic scaly patches elsewhere in the body, otherwise limited to pustular eruption on the palms and soles. When it erupts without any psoriasis lesions, however, some dermatologists consider it as a separate entity of unknown origin.
