Abstract:
Yellow dots are follicular ostium filled with keratin and/or sebum. Initially, they were exclusively associated with alopecia areata. Currently they have also been described in androgenetic alopecia, chronic cutaneous (discoid) lupus erythematosus, and dissecting cellulitis. Due to the growing importance of trichoscopy and its findings in the evaluation of the scalp, this article describes the main diseases in which yellow dots are a common trichoscopic finding, highlighting its characteristics in each dermatosis.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
