A three-year old patient had ichthyosis and neutral lipid storage disease (Chanarin-Dorfman syndrome), characterized by congenital ichthyosiform erythroderma and leukocyte vacuoles. He did not show any of the internal system involvement that was found in previously described cases. Patients with this syndrome demonstrate a great variability of clinical involvement. The affliction may be very mild as in our case or it may lead to rapid death, as with the patient's brother born a Harlequin baby, who only survived 5 days. Because of this wide spectrum of clinical variability mild cases might escape diagnosis. It is, therefore, suggested that every case of ichthyosis should have a peripheral blood smear evaluation with special attention to the morphology of the leukocytes. Our case clearly demonstrates the value of such a screening examination. Although the patient had been under treatment for almost 3 years, only screening examination of blood smears of all the patients with ichthyosis finally led to the correct diagnosis.
