The gene upregulation profile of female apocrine glands included several genes (MRO, DYRK3, SDK2, GLB1L, CATSPERB and PRPS2), which are specifically transcribed during testis differentiation and/or regulated by androgens. A chronic suppurative and cicatricial disease of the apocrine glands occurring chiefly in the axillae in women and in the groin and anal regions in men. A new method of isolating human sebaceous and apocrine sweat glands by the repeated dissection of skin biopsies with scissors is described.

Apocrine adenocarcinoma arises from apocrine sweat glands and therefore is mostly reported in areas of high apocrine gland density such as the axillae and the anogenital region. Pathogenesis: Early comedo – Hyperkeratosis of hair follicle infundibulum and androgen stimulation of sebum secretion. Acne is caused by the sebaceous glands, but genital acne occurs from the apocrine glands that are to be found in the groin region. The apocrine gland consists of a secretory portion in the deep dermis or subcutis and a short duct which enters into the infundibulum of the hair follicle, above the entry of the sebaceous duct. Q.

Inflammatory signalling is not prominent but a gender-specific response was detected, which is mostly associated with androgen-responsive genes in females and alterations of lipid metabolism in males. The lesions of acne (comedones) are the result of genetics (increased number and size of sebaceous glands), mechanical factors (accumulation of sloughed corneocytes leading to pilosebaceous unit blockage), hormones (androgens), bacteria (Propionibacterium acnes), and the inflammatory response in the pilosebaceous unit.
