Chronicles of A.I. Pospelov Moscow Society of Dermatovenereologists and Cosmetologists (MSDC was founded on October 4, 1891). Bulletin of the MSDC № 1149

On October 18, 2022, the 1149th meeting of the A.I. Pospelov Moscow Society of Dermatovenerologists and Cosmetologists (MSDC) took place. The meeting was held in a face-to-face format. There were 128 participants in total. Accepted as a member of the MSDC 53 people.

Two clinical cases are presented for discussion: trichoadenoma ― a rare benign follicular tumor consisting of strands of epithelial cells and keratinizing cysts embedded in the sclerotic stroma, and Darier’s follicular dyskeratosis ― hereditary dermatosis characterized by the formation of follicular hyperkeratotic vegetative papules on seborrheic areas of the skin caused by a violation of the keratinization process by the type of dyskeratosis.

Scientific reports were devoted to the analysis of differential diagnosis and therapeutic tactics in Brooke–Spiegler syndrome (multiple cylindromes and trichoepitheliomas), the mechanisms of action and effectiveness of zinc pyrithione as a means of controlling colonization of the hairy skin by fungi-commensals of the genus Malassezia, as well as the most urgent problems of modern medicine ― the features of the course of chronic-severe dermatoses after SARS-CoV-2 infection (COVID-19) and an increase in the incidence of mucormycosis, which is a marker of immune breakdown that occurs immediately after COVID-19 infections.
