• Rapid whitening of scalp hair developed during a three-month period along with a diffuse, subtotal alopecia in a patient. Immunofluorescence microscopy of biopsy material showed prominent deposits of IgG and IgM in a granular pattern in the epithelium of the lower portions of hair follicles. Some return of the color and amount of scalp hair occurred within a year, but occasional bouts of hair loss continued to occur. It is theorized that the rapid graying was caused by a selective loss of pigmented hair, which was perhaps caused by an immunologic mechanism. Some of the findings suggest that the cause of this patient's loss of hair color may be different from those of patients who have been previously described as having rapid whitening of scalp hair because of alopecia areata or vitiligo.
