Pseudoglandulárny (adenoidný, akantolytický) dlaždicovobunkový karcinóm penisu. Popis prípadu

Prezentovaný je prípad pseudoglandulárneho (adenoidného, akantolytického) dlaždicovobunkového karcinómu penisu u 60-ročného pacienta. Tumor obsahoval okrem štruktúr konvenčného dlaždicovobunkového karcinómu komponent pseudoglandulárny, ktorý napodobňoval tubuly adenokarcinómu. V epidermis vedľa tumoru nebola nájdená prekurzorová dysplastická lézia. Imunohistochemicky exprimovali bunky nádoru pancytokeratín AE1/AE3, p53 a p63, a boli negatívne na endotelové markery, CEA a p16. Farbenia na mucín boli negatívne. Metastázy boli prítomné v regionálnych lymfatických uzlinách a vo funiculus spermaticus. Štyri týždne po operácii sa objavili početné kožné/podkožné metastázy v podbrušku, v oboch ingvinách a na prednej mediálnej strane stehien. Vyšetrenie CT zistilo pakety metastaticky postihnutých lymfatických uzlín v panve. Vysoké štádium pri prezentácii tumoru a ďalší priebeh potvrdzujú, že pseudoglandulárny dlaždicovobunkový karcinóm penisu je vysoko agresívny tumor.
