Clinical, trichoscopic and confocal aspects of patient 1 at (A–E) T0 and (F–I) after treatment at T1. (A,B) Clinical and trichoscopic appearance at baseline. (C) Reflectance confocal microscopy (RCM) shows follicular pustule (yellow dashes) and inflammatory cells infiltrate (white arrows). (D,E) Confocal magnification demonstrates the presence of numerous inflammatory cells (white arrows) and dilated superficial vessels (red arrows). (F,G) Clinical and trichoscopic aspects after treatment. (H,I) RCM shows the presence of white papillae (blue arrows) and perifollicular fibrosis (white arrows). It should be noted that the patient shows (B,G) a slight decrease in the erythema score on trichoscopy, whereas on RCM it shows (D,I) a marked decrease of inflammatory cells.
