Warts are caused by the human papilloma virus. At least 60 types of human papilloma virus have been identified to date. None of them are strictly specific to a particular type of wart.
Herpetic skin lesions include simple vesicular lichen and herpes zoster. Simple vesicular lichen is caused by the herpes simplex virus type I or II, which is characterized by pronounced dermato-neurotropism. Infection with the type I virus usually occurs in early childhood (the possibility of intrauterine penetration of the virus into the body is allowed)
Granuloma annulare is a benign, chronic, idiopathic condition characterized by the presence of papules and nodules that, through peripheral growth, form rings around normal or slightly atrophic skin.
Rossolimo-Melkerson-Rosenthal syndrome is a chronically recurring dermatosis of unclear etiology. In its development, importance is given to genetic factors, functional disorders of the nervous system such as angioneurosis, and infectious-allergic mechanisms.
Berylliosis is a systemic occupational disease with predominant damage to the respiratory organs, which is based on the formation of typical immune granulomas from the introduction of metals.
Foreign body granuloma is caused by both endogenous and exogenous factors. Endogenous factors include keratin, sebum, urates, cholesterol and its crystals, etc.; exogenous factors include tattoo ink, paraffin, oils, silicone, etc.
Lichen sclerosus and atrophicus (syn.: guttate scleroderma, white spot disease, white lichen of Zumbusch). The question of the independence of this disease has not yet been resolved.
Scleroderma is a systemic connective tissue disease of unknown etiology, which is based on progressive collagen disorganization. The process consists of several links: mucoid swelling, fibrinoid changes, cellular reactions and sclerosis.
