Dorfman-Chanarin syndrome: a neutral lipid storage disorder

Dorfman-Chanarin syndrome is a rare, autosomal recessive inherited lipid storage disease with skin manifestations in form of congenital ichthyotic erythroderma. Demonstration of lipid vacuoles in neutrophils from peripherals blood smears in patients with ichthyotic erythroderma leads to the diagnosis. Other organ systems, such as CNS, liver, muscle, ears and eyes, are frequently involved. Since Dorfman-Chanarin syndrome may present with just skin findings, it should be included in the differential diagnosis of the congenital ichthyoses. Microscopic ex amination of peripheral blood smears is recommended in all patients with ichthyosis. We summarize the current data on the pathogenesis, diagnosis, differential diagnosis, and therapeutic options in Dorfman-Chanarin syndrome, give an overview of the clinical manifestations of the 23 patients described thus far and report a new patient affected with this rare disease.
