Gestational Trophoblastic Disease: Report of A Rare Case of Placental Site Trophoblastic Tumor

Gestational trophoblastic disease (GTD) is a spectrum of cellular proliferations arising from the placental villous trophoblasts encompassing four main clinicopathologic forms : hydatidiform mole (complete and partial), invasive mole, choriocarcinoma and placental site trophoblastic tumor (PSTT). Placental site trophoblasic tumours (PSTT) are rare and usually diagnosed after dilatation and curettage for missed abortion, but have also been described following term pregnancies and a hydatidiform mole. PSTT has a wide spectrum of clinical behaviour, ranging from a self-limited state to persistence to a highly aggressive metastatic neoplasm. A 23year old female G3p1l1a1 with 12weeks of gestation presented in the department with c/o per vaginal bleeding since 15days, her usg revealed triploid pregnancy with 4 th fetus which revealed placental site trophoblastic tumour. Here, we study a rare case of placental site trophoblastic tumor.
