Clinico-epidemiological profile of ichthyosis in south Indian patients

A high frequency rate of hereditary ichthyosis (141.89 per 1000) was detected in a 1029 member South Indian study population selected at random from the skin outpatients of a teaching hospital. An age and sex matched control population screened from the medical and pediatric outpatients of the same institute recorded the incidence of ichthyosis vulgaris as 150 per 1000 population which is even higher.
