Abstract:
We report a unique case of pressure-induced alopecia (PIA) in a 11-year-old boy following the use of electroencephalogram (EEG) electrodes on the scalp for 4 days. PIA is caused by localized ischemia leading to vascular congestion and discrete, often circumscribed patches of hair loss within 3-28 days of pressure interface. The synchronous conversion of follicles from anagen to catagen or telogen phase is the most distinctive finding of PIA. PIA is a nonscarring alopecia which often resolves over time without treatment.
