(a) Light brown hair in a girl with CHS, after bone marrow transplantation. (b) Wright stain of a peripheral blood smear from a classic CHS patient, showing abnormal giant granules in a polymorphonuclear leucocyte (arrows). (c) Light microscopy of hair shafts from a normal individual (top), a patient with CHS (middle), and a patient with GS2 (bottom). Uneven granularity characterizes the pigmentation pattern of the bottom two hair shafts. (d) Silvery gray hair of a boy with GS2.
