The eccrine glands are a type of sweat gland. They are abundant on the scalp (and even more abundant on the palms and soles). The eccrine gland openings can be more readily seen via trichoscopy (dermoscopy) in darker colored skin than lighter colored skin. This photo shows an arrow pointing to an eccrine gland opening. The variation in the thickness of hairs that can be seen in this image indicates an underlying diagnosis of androgenetic alopecia as well.
