Chronicles of A.I. Pospelov Moscow Dermatovenerology and Cosmetology Society (MDCS was founded on October 4, 1891) Bulletin of the MSDC № 1140

On November 17, 2020, the 1140th meeting was held in on-line format.

In total there were 92 participants. Five people were accepted as members of the MDCS.

The clinical agenda of the meeting considered cases of subacute (disseminated) cutaneous lupus erythematosus and reactions to tattooing in the form of pseudolymphoma of the skin. The interest of observing disseminated lupus erythematosus was in the difficulties of diagnosis due to its combination with Sjogren’s syndrome, a long history of the disease, the severity of the skin process and the peculiarities of the selection of adequate drug therapy. Analysis of the case of pseudolymphoma development as a reaction to a tattoo in a patient with atopic dermatitis helped to approach a more accurate understanding of the clinical and pathogenetic aspects of this process: probably, the pathophysiological reaction is based on a reaction to a foreign body, which makes this disease related to sarcoidosis.

The scientific agenda of the meeting reported on the advantages of using photodynamic therapy for skin T-cell lymphomas, such as good cosmetic results; non-invasive nature of the procedure; selectivity; low risk of toxicity; low photosensitivity; low carcinogenic potential. In another report ― on the use of signaling pathway blockers in the treatment of psoriasis ― the results of an open uncontrolled prospective clinical study of the effectiveness of apremilast in the treatment of moderate and severe psoriasis were presented.
