CASE REPORT:
The index case is a 25-year-old graduate who was brought to the outpatient department (OPD) by her mother with involuntary hair-pulling of one-year duration. On examination, she had patches of baldness over her head, mainly over the crown region (Figure 1). She would pull strands of hair as she felt restless and began pacing around the room. Initially it occurred 3-4 times daily, later progressed to 8-10 episodes for the past 2 months due to exam stress. Other than scalp hair, this behavior did not involve the eyebrows, armpits or pubic area.
