Bullous congenital ichthyosiform erythroderma associated with hypocalcemic vitamin D-resistant rickets

Abstract

There are several reports of an association between ichthyosis and rickets based mainly on a causative relationship through the impaired ability of ichthyotic skin to synthesize vitamin D. Hypocalcemic vitamin D-resistant rickets represents a specific type of rickets that is attributed to vitamin D receptor defect rather than to vitamin D deficiency. Nevertheless, an extremely rare association between bullous congenital ichthyosiform erythroderma and hypocalcemic vitamin D-resistant rickets is presented.
