The most characteristic trichoscopic findings of dissecting cellulitis are yellow, structureless areas and yellow dots with "3D" structure imposed over dystrophic hair shafts (2). Moreover black dots, yellow dots perifollicular pustules and pinpoint-like vessels with whitish halo may be also detected (2, 8).
In active lesions, mainly empty follicular openings, yellow dots and black dots are observed. Long-lasting, nonactive dissecting cellulitis is characterized by presence of yellowish/whitish areas with absence of follicular openings (8).
