A vesesejtes carcinoma (RCC) többféle, a veséből kiinduló rosszindulatú daganattípus gyűjtőneve. Az egyes entitások sajátos epidemiológiai, morfológiai, immunhisztokémiai, genetikai és klinikai jellemvonásokkal bírnak. Ezek együttes figyelembevételével került publikálásra 2016-ban a vesedaganatok aktuális WHO-klasszifikációja. Az eltelt három év során újabb, provizórikus RCC-altípusok kerültek leírásra, melyek egyelőre nem képezik részét a hivatalos beosztásnak. Ebben az összefoglalóban ezek az entitások kerülnek részletes áttekintésre. A szerzők bemutatják a következő daganattípusok klinikopatológiai jellegzetességeit: pajzsmirigyszerű follicularis carcinoma, az ALK-transzlokációhoz társult carcinoma, vesesejtes carcinoma prominens simaizomstromával, fumarát-hidratáz-deficiens carcinoma, bifázisos squamoid papillaris carcinoma, eosinophil solid és cysticus carcinoma, atrophiás vesére emlékeztető carcinoma, világossejtes carcinoma óriássejtekkel és emperipolesissel, Warthin-szerű papillaris carcinoma, low-grade oncocytás vesetumor (CD117-negatív, CK7-pozitív), high-grade oncocytás vesetumor, TCEB1-mutáns carcinoma és neuroendokrin vonásokkal rendelkező chromophob carcinoma. Ha a patológus követi az aktuális leletezési protokollokat, akkor ezek az entitások jórészt nem osztályozható RCC-ként kerülnek diagnosztizálásra. A munka meg kívánja ismertetni ezeket az altípusokat a hazai patológus-, onkológus- és urológusközösséggel azért, hogy javuljon a diagnosztikus pontosság, valamint hogy elkezdődhessen az ilyen esetek gyűjtése és további célzott vizsgálata is.
