Pressure Alopecia Occuring after a Cardiac Surgery in a Twelve Year-Old Child

Pressure alopecia is a preventable complication of surgery and long stays in the intensive care unit. Although reversible in most cases, it may result in a scarring alopecia. It classically manifests as a skin-colored alopecic patch on the occipital area. Trichoscopy shows black dots, comedone-like black dots and areas of scarring. Histopathology is not specific, it may show fibrosis, chronic inflammation, granulomatous foreign body reaction or catagen hair follicles with apoptotic bodies. Herein we report a case of a scarring pressure alopecia happening in a twelve year-old child occuring after a cardiac surgery. Trichoscopy showed areas of white fibrosis with no black dots or comedone-like black dots. The approach was to suggest a possible graft surgery when the child will be of age.
