Dorfman-Chanarin syndrome is a rare, autosomal recessive inherited lipid storage disease with congenital ichthyotic erythroderma due to an acylglycerol recycling defect. Demonstration of lipid vacuoles in neutrophils from peripheral blood smears (Jordans' anomaly) in patients with ichthyotic erythroderma leads to the diagnosis. In spite of frequent liver, muscle, ear, eye and central nervous system involvement, Dorfman-Chanarin syndrome may present clinically as monosymptomatic ichthyosis. Here, we report clinical and laboratory investigations in a consanguineous family from Turkey with 3 affected family members, and demonstrate the lipid vacuoles in epidermal Langerhans' cells for the first time. Langerhans' cell phenotyping suggests that the skin inflammation is due to the gene defect and not to underlying atopic dermatitis. Microscopic examination of eosinophils for lipid vacuoles to identify conductors revealed variable percentages of normal and vacuolized eosinophils in conductors, suggesting the microscopic analysis of at least 10 eosinophils for conductor identification.
