What type of epithelial tissue is affected in acne vulgaris?
Initially, the epithelial cells that line the hair follicle become abnormally sticky. These cells clog the follicular orifice with sebum, a substance produced by the sebaceous gland. The resulting lesions are referred to as open and closed comedones or, more commonly, blackheads and whiteheads.
What tissue is affected by acne?
Acne is an inflammatory disorder of the skin, which has sebaceous (oil) glands that connects to the hair follicle, which contains a fine hair. In healthy skin, the sebaceous glands make sebum that empties onto the skin surface through the pore, which is an opening in the follicle.
What tissues and cells does acne affect?

acnes bacteria can thrive. As the follicle becomes filled with sebum, dead cells, and bacteria, it begins to swell. The follicle wall ruptures and spills into the dermis.
How does acne affect the endocrine system?
Excess production of hormones, specifically androgens, GH, IGF-1, insulin, CRH, and glucocorticoids, is associated with increased rates of acne development. Acne may be a feature in many endocrine disorders, including polycystic ovary disease, Cushing syndrome, CAH, androgen-secreting tumors, and acromegaly.
