Prevalence of ichthyoses in Denmark: a nationwide registry-based study.

A study published in the British Journal of Dermatology provides insight into the prevalence of ichthyoses in Denmark. Ichthyosis is a group of genetic skin disorders characterized by dry and scaly skin. The study found that the prevalence of ichthyoses in Denmark is 1.6 per 10,000 people, with ichthyosis vulgaris being the most common type. The prevalence varied by age and sex, with higher rates in younger age groups and a higher prevalence in women over 50 years old. However, the study may underestimate the true prevalence and further research is needed. [Extracted from the article]
