How to distinguish acne vulgaris from occupational acne

Acne, commonly known as acne and acne, is a chronic skin disease that occurs in sebaceous glands of hair follicles. It is more common in the head, face, neck, chest, back and other parts with rich sebaceous glands. The main clinical manifestations are whitehead acne, blackhead acne, inflammatory papules, pustules, nodules and cysts. Except children, about 80% ~ 90% people in the population have or have had this disease (including mild diseases). Acne is a chronic skin disease that occurs in sebaceous glands of hair follicles. There are many factors that cause the disease, but the most direct factor is pore blockage. Acne is a common skin disease in adolescent children, and it is also relatively easy to get sick. If it is not handled properly, it will leave acne marks and scars. There are also different types of acne. Today, I will introduce the difference between acne vulgaris and occupational acne to my friends. The symptoms of acne vulgaris generally begin in adolescence, mainly in the forehead, cheeks and upper chest and back where sebum secretion is high. At first, it was mostly acne. With a little effort, you can squeeze out a fat suppository with black top and yellow bottom. In addition to acne, red papules and pustules can also appear, and in severe cases, dark red induration or cysts can appear. Some patients leave small sunken scars after healing, and some people have dark red scars on the mandibular angle or chest and back. In hot weather, the rash is often more serious. Clinically, it is divided into mild, moderate, severe or one to seven degrees according to the number of rashes; According to the main types of rash, it can be divided into papular acne, pustular acne and cystic acne. After puberty (about 25 years old), most patients' symptoms gradually ease or heal themselves, and serious patients gradually improve until about 30 years old. Symptoms of occupational acne Occupational acne refers to acne caused by contact with mineral oil or some halogenated hydrocarbons in production and labor. It is a chronic skin injury, and the incubation period depends on the nature, dosage, action time and individual quality of the exposed pathogen. The clinical manifestations of acne caused by various pathogens are different. According to the main pathogens and clinical manifestations, acne can be divided into two categories: oily acne and chloracne. Chloracne is an oil acne caused by coal tar, shale oil, natural petroleum and its high boiling point fractions and asphalt. Chloracne is caused by pyrolysis products of some halogenated aromatic hydrocarbons, polychlorinated phenol and polyvinyl chloride. Chloracne often occurs in small patches of hair follicle lesions at the contact site, with blackheads as the main manifestation. At the beginning, dense black spots with the size of a needle tip often appear in the lower part of the eye and zygomatic region. Over time, a large area of blackheads appeared around auricle, abdomen, buttocks and scrotum, accompanied by hair follicle squabble, occasionally miliary papulosis-like lesions, and inflammatory papules were rare. There are often grass-yellow cysts around the auricle and scrotum. Oily acne Oily acne can cause most hair follicle damage at the contact site, which is manifested as pore dilation, hair follicle extrusion, hair breakage and blackhead acne. There are often inflammatory papules, folliculitis, nodules and cysts. After the larger blackheads are squeezed out of the blackhead lipid embolus, they often leave a sunken scar. Skin lesions generally have no conscious symptoms or mild itching or tingling. Skin lesions often occur in eyelids, auricles, limbs, especially those that rub against oil-soaked clothes, but are not limited to the prone parts of acne vulgaris such as face, neck, chest, back and shoulders. Oily acne and chloracne both occur in areas that are frequently exposed to pathogens and can occur at any age. Under the same work and working conditions, there can be more patients of the same kind. After a certain period of time, the disease can be alleviated or cured, but the cyst is not easy to subside. After a certain period of time, the condition can be aggravated or recurred.
