Generalized pustular psoriasis is Pare in children. About 100 cases ha
ve been reported in the literature, Children generally have less sever
e lesions than adults. The annular and mixed patterns are more common
than the Zumbusch type erythrodermic pattern. Retinoid therapy has con
siderably improved the outcome, Two new cases of generalized pustular
psoriasis are reported in two brothers, both of whom had a history of
psoriasis vulgaris in infancy, Generalized pustular psoriasis of the Z
umbusch type occurred at ten years of age in one and 12 in the other.
Retinoid therapy was effective. Annular pustular psoriasis occurred at
each attempt to discontinue treatment. Familial cases of generalized
pustular psoriasis are extremely rare in the literature. Both brothers
carried the HLA Al and B17 antigens. Psoriasis vulgaris but not gener
alized pustular psoriasis has been reported to be associated with HLA
B17.
