Zosteriform atrophoderma of Pasini and Pierini.

Astophoderma of Pasini and Pierini is generally regarded as an atrophic variant of morphoea. It arises most commonly on the trunk and abdomen. We describe a 53-year-old man who had a 12-year history of unilateral atrophoderma of Pasini and Pierini affecting the left side of his trunk in a zosteriform distribution. Within these clinically atrophic lesions, there were localized areas of induration which were typical of morphoea. The patient also had a preceding history of balanitis xerotica obliterans. The occurrence of atrophoderma of Pasini and Pierini, morphoea and lichen sclerosus within the same individual supports the view that these conditions are closely related, and suggests that common factors may be involved in their aetiologies.
