Abstract
The term dots refers to hair follicle openings seen from the perspective of a dermoscope. Black dots are residues of pigmented hairs broken or destroyed at scalp level. Yellow dots are follicular infundibula with keratotic material and/or sebum. Fibrotic white dots represent fibrosis in areas of selective follicular destruction. Pinpoint white dots are observed in patients with dark skin phototypes. They correspond to empty hair follicles or to the epidermal portion of eccrine sweat ducts. Red dots have been described in discoid lupus erythematosus. Pink to pink-brown dots are a characteristic finding in the eyebrow area of patients with frontal fibrosing alopecia.
