How it was

On September 21, 2017, one of the key events for the industry took place in St. Petersburg: the school – seminar with international participation “Pathomorphological diagnostics of melanocytic formations”.

The seminar school was attended by specialists involved in the diagnosis and treatment of melanocytic formations. The event has become a unique platform for the exchange of experience, obtaining new knowledge and organizing joint integrated efforts to achieve a common goal – early detection of malignant neoplasms and reducing the mortality rate from them.

Pathomorphologists of general profile, as well as dermato- and oncopathologists were invited to participate. In general, the event brought together more than 150 specialists from all over Russia.

The format of the school was a training course, including theoretical and practical aspects of the diagnosis of melanocytic neoplasms. Special attention was paid to the moments that cause the greatest difficulties in the practical work of a pathologist:

  • differential diagnosis between sclerosing nevus and sclerosing melanoma;
  • differential diagnosis between nevus and melanoma of individual (specific) localizations;
  • differential diagnosis between BAP1-home and BAP1 melanoma;
  • differential diagnosis between infant spitzoid melanoma and spitz nevus;
  • differential diagnosis between sacral melanoma and sacral nevus;
  • differential diagnosis between nevoid melanoma and normal nevus;
  • Overview of the most common “diagnostic traps”.


The speaker of the school was a world-class expert – Professor Guido Massi (Department of Pathology, Catholic University Medical School, Rome, Italy). He also heads the Laboratory of Surgical Pathology (specializing mainly in dermatopathology) at the Complesso Integrato Columbus and the Department of Dermatopathology at the diagnostic laboratory “Laboratorio Inghirami” in Rome.




Guido Massi is the author and co-author of several books on dermatology, as well as many publications in peer-reviewed journals that address a wide range of dermatological diseases.



Within the school, participants were offered about 100 cases of melanocytic formations as independent work. All histological micro-preparations were presented on the portal in the form of high-quality digital slides, accompanied by brief clinical information. In practice, Guido Messi dealt in detail with the participants of the order of 25 complex and rare clinical cases, actively answering a lot of questions from specialists

“BioVitrum’’ also took part in the scientific program of the school.

Elizaveta Razvarina, head of the Morphology group, LLC “BioVitrum”, told the participants of the school about modern information technologies in pathologic and anatomical research. The company’s own IT products were presented, which are being successfully put into practice already now.

“BioVitrum” presented its full product portfolio for pathologic and anatomical research within the framework of the school seminar.

The organizers of the school – seminar with international participation “Pathomorphological diagnosis of melanocytic formations” were

  • The “BioVitrum”company
  • The St. Petersburg Clinical Scientific and Practical Center for Specialized Types of Medical Care (Oncological)”
  • The event was held with the support of the Russian Society of Pathologists.

“BioVitrumexpresses its gratitude to Ksenia Vladimirovna Shelekhova, MD, Head of the pathology department of the State Medical Institution “St. Petersburg Clinical Scientific and Practical Center for Specialized Types of Medical Care (Oncological)” for assistance in organizing the event.
