placental site trophoblastic tumor (pstt) is a very rare variant of gestational trophoblastic tumor. it can occur after normal termination of pregnancy or spontaneous abortion and ectopic or molar pregnancy. there is a wide range of clinical manifestations from a benign condition to an aggressive disease with fatal outcome. one of the most important characteristics of pstt, unlike other forms o...

A placental site trophoblastic tumor requires care in management and a prompt diagnosis. Placental site trophoblastic tumor is a rare type of gestational trophoblastic disease and displays non-specific presentations similar to those of uterine arteriovenous malformation and those of non-neoplastic gestational trophoblastic diseases such as placental polypoid tumor. Diagnosis from biopsy is extr...

  Placental site trophoblastic tumor (PSTT) is the rare variant of gestational trophoblastic diseases (GTD), which differs histologically and immunologically from GTD. Diagnosis of PSTT is often difficult and delayed. In most cases, diagnosis is not possible until the surgery is performed. The most therapeutic choice is hysterectomy and it is usually successful. Here we report two cases of PST...

Placental site nodule, developing from intermediate trophoblasts, is a rare benign lesion. Although it is a benign lesion, it is histopathological differential diagnosis from placental site trophoblastic tumor and epithelioid trophoblastic tumor which are aggressive lesions of the intermediate trophoblasts, and non-trophoblastic neoplasms such as squamous cell carcinoma, is important due to its...

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 cure...

Gestational trophoblastic disease includes hydatidiform mole (complete and partial) and gestational trophoblastic neoplasia (invasive mole, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor). The epidemiology, pathology, clinical presentation, and diagnosis of each of these trophoblastic disease variants are discussed. Particular emphasis is given to manag...
