General description
Human placental lactogen (hPL), also previously known as "human chorionic somatomammotropin", is a 22 kD protein with partial homology to growth hormone. hPL is first detectable in the maternal serum in the fifth week of gestation and reaches a plateau by the thirty-fourth week. hPL has been demonstrated by immunochemistry in the syncytiotrophoblastic cells of choriocarcinoma. A rare variant of trophoblastic tumor has been reported in the testis with resemblance to uterine placental site trophoblastic tumor. It consists purely of intermediate trophoblasts which are diffusely positive for hPL and focally for β-hCG.

We report two unusual forms of testicular trophoblastic tumor. One was a mixed germ cell tumor in a 19-year-old man that had a predominant component of nodules of cytotrophoblast cells with only rare syncytiotrophoblast cells. These nodules of "monophasic" choriocarcinoma

Human trophoblast is composed of a heterogeneous population of cells, which give rise to a variety of trophoblastic tumors and tumor-like lesions. In this report, we analyzed the expression pattern of the p63 gene, a transcription factor belonging to the
