The great majority (approximately 95%) of primary testicular tumors, including seminoma, embryonal carcinoma, YST, choriocarcinoma, and others, are of germ cell origin, and accurate subtyping is important for proper management and prognosis.
One study found that TBBPA up-regulates aromatase expression and activity in human choriocarcinoma cells for up to 72 h in vitro (Honkisz and Wojtowicz 2015).
In choriocarcinoma, trophoblastic cells stain for HCG, CD10 and cytokeratin, but are negative for EMA.
