Keratosis follicular (Contagious) is a skin disease characterized by the appearance of nodular formations on the face or body. It occurs as a result of disruption of the sebaceous glands and increased sebum synthesis. The disease occurs due to exposure to unfavorable factors: genetic predisposition, hormonal imbalance, excessive sun exposure, poor nutrition.
To begin with, it is worth mentioning that there are several forms of this disease. Keratosis can be:
– follicular (develops at the mouth of the hair follicle, the so-called “navel”); – smallpox-like (nodular formation looks like an intradermal red papule).
The most common form of keratosis is follicular. In typical cases, the manifestations of the disease are as follows: the skin in the affected area may be somewhat discolored, and there may be a feeling of roughness. If left untreated, the rash can spread to adjacent areas of the skin. The development of the process can take several months or even years. Follicular type keratosis is more typical for males. The most common sites of occurrence of the disease are the face, chest, neck, forearms and shoulders, as well as the scalp and legs. The exact etiology of this disease is unknown. According to some data, changes in metabolism in epithelial cells play an important role here. The acid-base balance is disrupted and the pH of sebum decreases, the amount of lipase that breaks down fats decreases, and excess glycolipids are synthesized. Patients experience persistent increased sebum secretion and hyperkeratosis - excessive formation of horny scales. Content of free fatty acids in
Keratosis follicularis contagiosum is a contagious dermatosis from the group of contagious warts caused by a filterable virus.
The main and most common route of infection is contact; less often, infection occurs through household items and personal belongings. Cases of infection of the fetus from the mother are limited. It is transmitted mainly through direct contact, through mucous membranes and damaged skin. The virus can survive on handrails, door handles, toothbrushes, cutting boards, and dishes. In families
