ABSTRACT

We report seven cases of urticaria pigmentosa (UP) in three sibships belonging to separate families. The affected persons had normal parents. UP probably is an etiologically heterogeneous disorder. In familial cases, the usual pattern of inheritance is autosomal dominant but here UP appears to be an autosomal recessive entity.

Keywords: urticaria pigmentosa.
