Acne

The oily product of the sebaceous gland is carried through the hair follicle from which the hair shaft emerges. It serves as a duct to carry the oily substance to the skin surface. The oily product is controlled by the level of hormones and increases substantially at puberty, then continues at an increased rate into advanced adult life. An important disease of the skin is acne ( acne vulgaris ), which occurs on the face, shoulders, and upper trunk of adolescents.
Main features
The hallow of acne vulgaris is the comedo, commonly known as the blackhead. The comedo consists of a mixture of keratinous debris and sebum( the oily substance) that lodges in the mouth of the duct. Affected areas of the skin also exhibit inflamed papules, pustules, and cysts. The inflammation is caused by leakage of sebum and keratin debris outside the swollen duct.
Types of Acne
The bacillus Propionibacterium acne,
It populates the lesions, and may also contribute indirectly to the inflammation by metabolising the sebum to produce irritant fatty acids. Eruptions can be brought on by contact with dirty oils or tars and halogenated hydrocarbons.
Chloracne
It is caused by exposure to chlorine compounds, and may develop in workers involved in the manufacture of cables, insecticides, fungicides, and herbicides. Industrial accidents involving the release of tetrachlorodibenzodioxin vapour have caused severe community outbreaks of chloracne.
Acne rosacea,
An acne of middle age that exhibits nodular swelling of tissues in the face, is a disease that occurs rarely among blacks.
