title: [Morphology of sweat glands].
abstract: There are two types of sweat glands: eccrine glands, which do not show cytological changes during secretion and apocrine glands, characterised by decapitation secretion, in which part of the cell is pinched off and released into the lumen. Eccrine glands play a major role in thermoregulation and electrolyte balance. They are present everywhere in the human skin and are composed of a secretory portion, an intradermal duct and an upper intraepidermal part, called acrosyringium. The acrosyringium has a unique symmetrical and helicoidal course, which length is correlated to the thickness of the epidermis. Apocrine glands are located only on genital, axillary and mammary areas, where they are always connected to a hair follicle. Their exact role in humans is unknown. A third type of intermediate sweat glands, the apoeccrine glands, was recently described in axillary areas. Sweat glands can be involved in various inflammatory processes and can lead to a large range of both benign and malignant tumors.
