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...

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...

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...

It is now well established that human placenta secretes a protein hormone Human Placental Lactogen (HPL), also referred to as placental Somatomarnmotropin. It shows immunological crossreactivity with pituitary growth hormone and possesses both mammotropi.c and somatotropic effects (Jasiomovich and Maclaren, 1962, Kaplan and Grumbach 1968). This hormone is produced by syncytiotrophoblast layer o...

The World Health Organisation’s (WHO) classification of gestational trophoblastic disease includes complete, partial, invasive and metastatic hydatidiform mole, exaggerated placental site nodule or plaque and two malignant tumoursplacental site trophoblastic tumour and choriocarcinoma [1]. The incidence of gestational trophoblastic disease (GTD) in Sri Lanka according to a hospital based study ...
