Palmoplantar pustular psoriasis is characterised by numerous small, sterile yellow pustules and widespread erythema localised to the palms and soles (1).
The disease may effect a single foot or hand, or the entire surface of both feet and hands.
Pustular palmoplantar psoriasis is associated with classical psoriasis vulgaris in around 25% of the patients (1).
It differs from chronic plaque psoriasis from the following factors:
It is a chronic condition (2). The pustules gradually change into circular, brown, scaly spots and in time, peel off (1). They are uncomfortable or painful rather than itchy.
Psoriatic nail involvement can be commonly seen in palmoplantar pustular psoriasis (1).
