    A placental site trophoblastic tumor is a monophasic neoplasm of the implantation site intermediate trophoblast, and usually a benign lesion, which comprises less than 2% of all gestational trophoblastic proliferations. Preceding conditions include molar pregnancy (5%).

    Management of GTN requires pathology review, treatment options and monitoring of hCG. Therefore, it can be treated with curettage, hysterectomy and single agent or multi agent chemotherapy. [ 4 ] Although this group of diseases are highly susceptible to chemotherapy, prognosis depends on the type of GTN and whether the tumor has spread to other ...

    Both are composed of intermediate trophoblast, but their morphological features and clinical presentation can differ significantly. Exaggerated placental site is a benign, non cancerous lesion with an increased number of implantation site intermediate trophoblastic cells that infiltrate the endometrium and the underlying myometrium .

    Gestational choriocarcinoma is a form of gestational trophoblastic neoplasia, which is a type of gestational trophoblastic disease (GTD), that can occur during pregnancy.It is a rare disease where the trophoblast, a layer of cells surrounding the blastocyst, undergoes abnormal developments, leading to trophoblastic tumors.

  8. Treatment can occasionally consist of "watchful waiting" (e.g., in CLL) or symptomatic treatment (e.g., blood transfusions in MDS). The more aggressive forms of disease require treatment with chemotherapy, radiotherapy, immunotherapy and—in some cases—a bone marrow transplant.
