OBJECTIVE To investigate a large series of placental site trophoblastic tumours (PSTT) and epithelioid trophoblastic tumours (ETT) and determine the relationship between their development and the type and sex of both the immediately antecedent and causative pregnancies. METHODS The antecedent pregnancy was determined from patient records in 92 cases with a confirmed diagnosis of PSTT, ETT or ...

To the best of the authors' knowledge, no case of placental site trophoblastic tumor (PSTT) pertinent to twin pregnancy has yet been published. There are only few case reports concerning patients with PSTT who were successfully treated by fertility-sparing methods. A 29-year-old nulliparous woman was admitted to hospital in the 36th week of a twin pregnancy due to symptoms of preterm labor. She...

OBJECTIVE To investigate clinical features and ultrasound findings in cases of placental site trophoblastic tumor (PSTT). METHODS Fourteen cases of PSTT treated at our institution between May 2004 and October 2010 were identified and the clinical features and findings on transvaginal sonography (TVS) were investigated. Pathological confirmation of PSTT was obtained in all cases. RESULTS The...

A 20-year-old male presented with persistent right testicular pain. Following ultrasound detection of testicular nodules and biopsy for intraoperative consultation which yielded germ cell tumour, he underwent radical orchidectomy. A predominantly whitish cyst and a lobulated, variegated nodule were identified. Histology showed a mature cystic teratoma with a focus of infiltrative epithelioid ce...

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...

Indications and outcomes of hysterectomy in women with gestational trophoblastic neoplasia (GTN) were reviewed at Chiang Mai University Hospital, Chiang Mai, Thailand. From January 1998 through December 2008, 18 women underwent simple transabdominal hysterectomy (TAH). Indications for TAH included suspicious lesions confined to the uterus (5), chemoresistant lesions confined to the uterus (7), ...

The anteromedial superior cerebellar tumor can be accessed by various routes. For tumor presenting at the cerebellar surface in this region, the optimal approach remains contentious. Furthermore, which of the various routes offers the optimal approach to a tumor that is not present at the cerebellar surface but lies deep anteromedial superior cerebellum is a matter of debate. We report herein t...

Placental site trophoblastic tumor (PSTT) is a rare type of gestational trophoblastic neoplasia (GTN). It is rising from the abnormal proliferation of intermediate trophoblastic cells with occasional multinuclear giant cells, with the potential for local invasion and metastasis. For its untypical and changeable clinical characteristics, the diagnosis and management are still poorly understood. ...
