A Case of Transient Acantholytic Dermatosis with a Linear Distributution

Abstract

We described a 67-year-old man with relapsing, linearly arrayed papules and vesicles on the left leg for the previous three years. Light microscopic observation revealed epidermal acantholysis with inflamatory cell infiltration. The patient was diagnosed as having transient acantholytic dermatosis (TAD) with linear configuration following the lines of Blaschko. Only two TAD cases have been reported with a zostoriform distribution. Our case may be a first report of TAD with a linear pattern.
