Rickets associated with ichthyosis.

Nutritional rickets in disorders of keratinisation is very rare. A 12-year-old girl with autosomal dominant ichthyosis vulgaris is reported who presented with tetany and a waddling gait. She had the classic clinical, biochemical and radiological features of rickets. She was treated with vitamin D and calcium supplements together with keratolytic and emollient agents, which was followed by biochemical and clinical remission. This appears to be the first report of rickets associated with autosomal dominant ichthyosis vulgaris.
