Chronicles of A.I. Pospelov Moscow Dermatovenerology and Cosmetology Society (MDCS was founded on October 4, 1891) Bulletin of the MSDC

The 1147^th meeting was held in a face-to-face format. In total there were 95 participants. Four people were accepted as members of the MSDC.

Among the clinical observations presented at the meeting were patients with psoriatic erythroderma (two cases) and erythroderma in Deverji’s disease. Erythroderma is a severe, often life threatening condition characterized by a universal inflammatory lesion of the skin, itching, generalized lymphadenopathy and fever. A case of cryoglobulinemic vasculitis, characterized by polymorphism of the course and a tendency to necrosis, is also presented in a 65-year-old patient who developed drug-induced Itsenko–Cushing syndrome during treatment. A case of multiform exudative erythema was also considered in a 40-year-old patient with abundant rashes on the skin of the trunk and extremities caused by subacute SARS-CoV-2-associated myocarditis of high immunological activity, moderate course.

The topics of scientific reports were devoted to auto-inflammatory syndrome (SAPHO; PEPA; PUSH; PUSH) and acne. It has been reported that biological anticytokine therapy ― IL-1 antagonists ― is the most acceptable for the treatment of all syndromes with the main dermatological manifestation in the form of acne. For severe forms of acne, an algorithm for patient management was proposed.
