Souhrn

Popísaný je prípad vaginálneho myofibroblastómu, ktorý obsahoval žliazky pozitívne imunohistochemicky na mamárne a prostatické markery. Jednalo sa o tumor zistený u70-ročnej pacientky v proximálnej tretine vagíny. Morfológia a imunofenotyp lézie boli typické pre cervikovaginálny myofibroblastóm. Periférna subepitelová zóna tumoru obsahovala niekoľko skupín žliazok, u ktorých bola predpokladaná pri prvom vyšetrení diagnóza vaginálnej adenózy alebo prostatických žliazok. Imunohistochémia ukázala prekvapujúcu pozitivitu týchto žliazok na prostatické i mamárne markery súčasne (prostatický špecifický antigén, prostatická kyslá fosfatáza, mamaglobín, GCDFP-15). Myoepitel žliazok exprimoval hladkosvalový aktín, p63 a CD10. Nález ukazuje, že pri vyšetrení glandulárnych lézií dolného genitálneho traktu ženy môže simultánne vyšetrenie na prostatické a mamárne antigény byť prínosom pre diagnózu i pre ďalšie poznanie mamárnej a prostatickej diferenciácie v tejto lokalizácii.
