There were 102 participants and 5 applicants.

Our agenda included two clinical cases: the first one was a clinical case of fulminant acne (Miderm Clinic); the second one was about gangrenous pyoderma as a possible marker or paraneoplasia in intestinal oncological diseases (Sechenov University). We present clinical cases of patients with fulminant acne and periorbital oedema in the first report, and ascending colon tumour and T3N0M0 rectal cancer in the second report.
