On March 16, 2021, the 1142nd meeting of the Moscow Society of Dermatovenereologists and Cosmetologists named after A.I. Pospelov took place.
 Two people have been accepted as members of the MODV: the list of new members was approved unanimously.
 The agenda includes a discussion of two clinical cases. The interest in the first demonstration ― mushroom mycosis lies in the relative rarity of T-cell lymphomas in the skin clinic, as well as the effectiveness of PUVA therapy in the plaque stage of the disease. Another observation is a case of acquired epidermolysis bullosa, a rare sporadic autoimmune disease with increased skin injury, the formation of subepidermal blisters, the presence of antibodies against type 7 collagen, the prognosis for which is usually favorable and even with a possible spontaneous recovery.
 A number of scientific reports were made at the meeting. The first of them is on the problems of vulgar acne. The patient-oriented approach for vulgar acne implies individual, personalized treatment of the patient. Among the strategic directions in the development of therapeutic approaches to patients with vulgar acne, special attention, in addition to external remedies, systemic therapy, physiotherapy and cosmetic care, should be paid to the adherence of patients to treatment. Among the various technologies for determining the severity of vulgar acne, an interactive electronic DIA calculator developed at the Department of Skin Diseases of Sechenov University, combined with medicinal recommendations in accordance with a certain severity of the disease of a particular patient, deserves attention.
 The report on modern and classical methods of diagnosis of human and animal mycoses represents the most pressing issues of medical mycology in general and dermatomycology in particular due to their extreme prevalence. To date, all laboratory methods for the diagnosis of mycoses can be divided into classical and modern high-tech, while in most laboratories on the ground, almost only confocal microscopy has been introduced.
 The last report was devoted to dermatoses that developed at the site of tattoos and tattooing. Since the composition of the coloring pigment includes iron oxide, titanium dioxide, isopropyl alcohol, natural organic and inorganic pigments, dermatoses such as benign lymphoplasia (lymphocytoma), sarcoidosis, psoriasis, discoid lupus, vitiligo, vasculitis, lichen planus, annular granuloma, lipoid necrobiosis, melanoma may develop in places of skin damage, basal cell carcinoma, gangrenous pyoderma, mycosis, syphilis, tuberculosis. It is noted that the treatment of lymphocytoma and sarcoidosis is a difficult task.
