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...

Invasive mole is a benign gestational trophoblastic disease that arises from the myometrial invasion of any gestational event via direct extension through tissue or vascular structures. Invasive mole (and other gestational trophoblastic diseases) may present with life-threatening complications including uterine perforation, excessive bleeding, acute hemoperitoneum, and abdominal pain. We report...

Background Gestational trophoblastic disease (GTD) defines a heterogenenous group of interrelated lesions that arise from the trophoblastic epithelium of the placenta. There are several histologically distinct types of GTD: hydatiform mole (complete or partial), persistant/invasive gestational trophoblastic neoplasia (GTN), choriocarcinoma and placenta site trophoblastic tumors. The aim of this...

Background—The p21 gene mediates growth arrest by inhibiting G1 cyclin dependent kinases and has been considered as a downstream eVector of the tumour suppressor gene p53. Aim—To analyse the role of p21 in gestational trophoblastic disease. Methods—The immunohistochemical expression of p21 gene was measured in 33 placentas, 28 partial hydatidiform moles, 54 complete hydatidiform moles, and 13 c...

Gestational trophoblastic neoplasms are a group of fetal trophoblastic tumors including choriocarcinomas, epithelioid trophoblastic tumors (ETTs), and placental site trophoblastic tumors (PSTTs). Mixed gestational trophoblastic neoplasms are extremely rare. The existence of mixed gestational trophoblastic neoplasms that were composed of choriocarcinoma and/or PSTT and/or ETT was also reported. ...

Masaharu Fukunaga, M.D. Department of Pathology, the Jikei University Daisan Hospital, Tokyo, Japan Hydatidiform moles With the increased use of ultrasound hydatidiform mole (HM) is being diagnosed at increasingly early stages of gestation. As villous edema is not fully developed, we cannot make a diagnosis of HM by macroscopic observation. Furthermore, microscopically the classic features of c...

BACKGROUND AND INTRODUCTION Gestational trophoblastic disease (GTD) is a disease of the proliferative trophoblastic allograft. Diagnosis and treatment of GTN in low resource-income countries is challenging due to numerous factors. The objective of this study was to review outcomes of gestational trophoblastic neoplasia in women of low socioeconomic status with limited resources and social suppo...

Gestational trophoblastic disease (GTD) is characterized by abnormal proliferation of pregnancy-associated trophoblastic tissue with malignant potential. GTD covers a spectrum of tumors and tumor-like conditions and may occur in a benign form as hydatiform mole or as malignancy in the form of invasive mole or choriocarcinoma. GTD has become a curable malignant disease since the introduction of ...

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...
