Placental site trophoblastic tumor with sole metastasis to breast: A case report
نویسندگان
چکیده
Placental site trophoblastic tumor (PSTT) is a rare form of gestational trophoblastic neoplasia (GTN). It most commonly occurs after a delivery but may arise after any type of pregnancy. PSTT arises after neoplastic transformation of intermediate trophoblastic cells. The most commonly reported symptoms are abnormal bleeding or amenorrhea. Due to the rarity of this disease, evidence on prognostic factors as well as optimal treatment is limited. While treatment for early-stage disease is usually limited to surgery, multimodal treatment with chemotherapy and surgery may be important for metastatic disease. Metastatic disease may be associated with minimal elevations of human chorionic gonadotropin (hCG). Here we present an unusual case of a patient with PSTT and an isolated breast metastasis who was successfully treated with surgical resection and single-agent chemotherapy.

Placenta Site Trophoblastic Tumor and Choriocarcinoma from Previous Cesarean Section Scar: Case Reports
Choriocarcinoma and placental site trophoblastic tumor (PSTT) are rare varieties of gestational trophoblastic disease (GTD). PSTT alone constitutes about 1-2% of all trophoblastic tumors, which presents at early reproductive age and the serum beta-hCG level is much lower than choriocarcinoma. This tumor usually invades the myometrium and its depth of penetration is a prognostic factor. The firs...

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...
متن کاملBreast Cancer Metastasis to Pituitary Infandibulum
Metastasis from breast cancer to other parts of the body is very common, but the spread of the tumor to pituitary gland, especially to infandibulum, is a rare presentation. At the time of pituitary metastasis, a majority of the patients have clinical and radiological evidence of the disease. It seems that the posterior area of the gland is the most common site of metastasis, probably due to hig...
متن کاملPrimary epithelioid trophoblastic tumor with a synchronous breast carcinoma detected only with FDG-PET/CT Scan.
Epithelioid trophoblastic tumor is a recently described, rare and distinctive type of gestational trophoblastic tumor. We report the case of a 31-year old patient who had a full-term pregnancy 18 months before presentation. She had a right axillary lymph node metastasis and was referred for FDG-PET/CT scan for evaluation of distant metastasis and to detect primary malignancy. The axillary lymph...
متن کاملPlacental site trophoblastic tumor presented with vaginal metastasis.
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. ...
