Case #162 – August, 2005

A 6-year-old girl complained to her parents that her head was itchy after returning from a 4-week summer camp in the southeastern United States. Her parents took her to the doctor where she was examined. The doctor observed small, whitish objects located near the base of hair shafts on the scalp. Although the physician was able to make a diagnosis based on what he observed on the patient’s scalp, he did collect a few hairs to examine under the microscope. Figure A shows the objects that were found on the girl’s head and Figure B shows a close up of the objects that were found on the girl’s hair shafts. What is your diagnosis? Based on what criteria?
