Comments

This 46-year-old man was evaluated for asymptomatic patches on the trunk that developed after he moved to the United States 10 years ago. He had a one year history of type 2 diabetes that was well controlled with an oral hypoglycemic. The histologic changes are typical of pityriasis rotunda and ichthyosis vulgaris.
