Abstract

On December 21, 2021, the 1145th meeting of the Moscow Society of Dermatovenereologists and Cosmetologists named after A.I. Pospelov took place.
 The meeting was held in a face-to-face format traditionally in the countries of the V.A. Rakhmanov Skin Clinic. There were 110 participants. Accepted as a member of the MSDV 4 people.
 Clinical observations of linear IgA-dependent dermatosis, systemic lupus erythematosus, annular granuloma were presented. Two scientific reports were heard ― about foot mycetoma; about skin reactions to tattoos.
 Linear IgA-dependent bullous dermatosis is a rare immune ― mediated vesicular skin disease characterized by the presence of homogeneous linear fixation of IgA along the basement membrane. Trigger factors: medications (vancomycin, cephalosporins, diclofenac, captopril, etc.); infectious diseases; vaccination against influenza; exposure to ultraviolet rays; paraneoplastic process (5% of cases) in lymphoproliferative diseases; inflammatory bowel diseases (ulcerative colitis and Crohns disease). The differential diagnosis in adults is Durings herpetiform dermatitis, Levers bullous pemphigoid, an atypical form of multiform exudative erythema; in children ― bullous impetigo, genetic epidermolysis bullosa.
 Systemic lupus erythematosus is a multisystem connective tissue disease with lesions of the skin and mucous membranes, joints, kidneys, heart, lungs and central nervous system. Systemic glucocorticoids, hydroxychloroquine, azathioprine, cyclophosphamide, belimumab, rituximab are used in the treatment.
 Annular granuloma is a benign inflammatory dermatosis of unknown etiology, which is characterized by the development of flesh colored or red papules on the skin, often arranged in the form of rings. Fractional laser action is used in the treatment.
 Mycetoma is a one sided, slightly painful dense tumor-like infiltrate limited on the foot or hand, edema with the formation of granulomas, microabcesses, the formation of fistulas and the release of actinomycetes or fungal mycelium from them. Differential diagnosis: chronic arthritis, arthrosis, sprain and rupture of ligaments, synovitis, chronic and postoperative osteomyelitis, bacterial mycetoma, botryomycosis, tumors, cold abscess, phlegmon, post-injection infiltrate, etc.
 Tattooing is a subspecies of avant ― garde art and a way of changing appearance, in which the integrity of the skin is violated with the help of various piercing tools and a persistent indelible pattern is applied by introducing a coloring agent. The pigments trapped in the tattoo partially exit through the lymph and are deposited in the regional lymph nodes. The nodes are imperceptibly colored along with the skin. A certain amount of pigment nanoparticles can enter the bloodstream and theoretically cause harm somewhere in the body.
