Souhrn

Atypický fibroxantóm (AFX) je zriedkavý kožný mäkko-tkanivový nádor typicky sa vyskytujúci u starších ľudí na koži vystavenej slnečnému žiareniu. Histologicky je tvorený pleomorfnými atypickými bunkami s početnými mitózami vrátane atypických mitóz, čím pripomína nediferencovaný malígny nádor. AFX je považovaný za benígny nádor s takmer výlučne excelentnou prognózou po konzervatívnej liečbe, ak sú použité prísne diagnostické kritériá. Prezentujeme prípad 68-ročného muža s nádorom kože v temporo-parietálnej oblasti. Histomorfologické a imunohistochemické nálezy zodpovedali diagnóze atypického fibroxantómu. Ponúkame prehľad terminológie a kategorizácie tohto nádoru a spektrum imunohistochemických markerov nápomocných v diferenciálne-diagnostickom procese na vylúčenie iných malígnych nádorov, pretože AFX je diagnóza per exclusionem. Správnou diagnózou sa vyhneme nepotrebnej liečbe pacienta.

Klíčová slova:

Atypický fibroxantóm – nediferencovaný pleomorfný sarkóm – imunohistochémia.
