Who is prone to occupational acne?

summary

Occupational acne refers to the chronic inflammatory damage of skin hair follicle and sebaceous gland system caused by contact with mineral oil or some halogenated hydrocarbons in production. Oil acne is caused by coal tar, shale oil, natural oil, high boiling point fractionation products and asphalt; Chloroacne is caused by some halogenated aromatic hydrocarbons, polychlorinated phenols and pyrolytic products of polyvinyl chloride.

Who is prone to occupational acne?

The etiology of oil acne: the chemical stimulation of mineral oil on the structure of sebaceous glands in hair follicles causes excessive proliferation and keratinization of epithelial cells at the mouth of hair follicles, resulting in the disorder of sebum excretion; Mechanical obstruction; Folliculitis and furuncle may be related to secondary bacterial infection; It is related to the physiological function of sebaceous glands and work experience of patients. Cause of chloracne: it is related to hyperplasia of squamous epithelium of sebaceous glands and thickening of outer root sheath of hair follicle.

Oil acne. Most of the hair follicles were damaged in the contact area, such as pore expansion, hair follicle angulation, broken hair and blackhead acne. There are often inflammatory papules, folliculitis, nodules and cysts. Larger blackhead acne after extrusion of blackhead lipid embolism, often leaving a concave scar. Skin lesions generally have no symptoms or mild itching or tingling. It usually occurs in the eyelids, auricles, limbs, especially in the friction parts with oil impregnated clothes, but not limited to the common acne prone parts such as face, neck, chest, back and shoulder.

Chlorine acne. There were a lot of follicular lesions in the contact area, mainly blackhead and acne. At the beginning, there are often dense small black spots with large needle tip at the lower part of the eye and zygomatic region. Over time, there are large black spots around the auricle, abdomen, buttocks and scrotum, accompanied by hair follicle angulation, occasionally with miliary papule like lesions. Inflammatory papules are rare. There are often grass yellow cysts around the auricle and scrotum.

matters needing attention

1. Occupational acne generally does not affect the ability to work, in the case of strengthening protection, can continue to engage in the original work. If the treatment of multiple folliculitis, multiple cysts and aggregate acne is ineffective, we can consider changing jobs to avoid contact with pathogens. 2. Before employment, dermatology examination should be done and detailed records should be made. Regular physical examination should be carried out every 1-2 years. Attention should be paid to whether acne like lesions occur, and whether it is related to occupation should be identified. 3. Patients with obvious sebum spillage or severe acne vulgaris should not be exposed to tar, asphalt, mineral oil with high boiling point, polychlorobenzene, polychloroacetyls, polychlorophenols and some brominated aromatic compounds.
