Family history was positive for similar disease in his eldest sister, who died at 6 months of age without a diagnosis. On examination, the patient looked ill with generalized erythroderma, yet there were no signs of ectropion, eclabium, or deformed ears. Diffuse scalp scaling was observed with interlocking tessellation scales over the scalp (Figure 1). Hair microscopy showed in Figure 2. All laboratory results were normal.
