Mezenchymální kožní tumory – Nové jednotky v 5. edici WHO klasifikaci nádorů kůže

Mesenchymal skin tumors – Novel entities in the 5th edition of WHO classification of skin tumors

The section on mesenchymal tumors in 5th edition of WHO classification of skin tumors has undergone several changes, the most important of which, as usual, is the inclusion of newly identified tumor entities, which will be the main focus of this review article. These specifically include three novel cutaneous mesenchymal tumors with melanocytic differentiation, and rearrangements of the CRTC1::TRIM11, ACTIN::MITF, and MITF::CREM genes. In addition, EWSR1::SMAD3-rearranged fibroblastic tumors, superficial CD34-positive fibroblastic tumors, and NTRK-rearranged spindle cell neoplasms were newly included. Of the other changes, only the most important ones will be briefly mentioned

Souhrn

V roce 2023 vydávaná 5. edice WHO klasifikace nádorů kůže doznala v sekci mezenchymálních nádorů několika změn, přičemž mezi nejvýznamnější, jako již tradičně, patří zařazení nově identifikovaných nádorových jednotek, kterými se tento přehledový článek bude zabývat především. Konkrétně se jedná o tři nové kožní mezenchymální tumory s melanocytární diferenciací a rearanžemi genů CRTC1::TRIM11, ACTIN::MITF a MITF::CREM. Dále byly nově zařazeny EWSR1::SMAD3- rearanžované fibroblastické tumory, superficiální CD34 pozitivní fibroblastické tumory a NTRK-rearanžované vřetenobuněčné neoplazie. Z dalších změn budou krátce zmíněny pouze ty nejvýznamnější.
