3. Pustular
This form can be localized or generalized, where pimples appear similar to those of juvenile acne, pruritic and full of yellowish liquid that causes itching. It is not dangerous but it is extremely penalizing on an aesthetic level. The localized form is preferentially manifested in the palmar and plantar area. In this case, we speak of psoriasis plantar palmar of Barber, which can also cover the nails that are attacked and weakened by infection. It can appear as small vesicles sub corn which superficializes by scaling.
If it is extended to the whole body it is called generalized pustular psoriasis of Von Zumbusch, signs of erythema, hyperkeratosis, and fissures appear in the most violent forms. A pustule can be of two types: a pustule with a circular center full of pus, like a small pimple, or a dark pustule similar to a bladder with a red circular contour. The skin becomes inflamed, dries and thins to break up a pustule. It is important to keep the affected area disinfected.
