Introduction: Gestational trophoblastic disease (GTD) includes hydatiform mole, choriocarcinoma, placental site tumor, and epithelial tumor. Also, molar pregnancy can happen as an ectopic pregnancy. The coincidence of these complicated pregnancies seems to occur extremely rarely. Case presentation: Here, we presented a 26-year-old woman, nulli gravida with the first presentation intrauterine co...

Chorangiocarcinoma is an extremely rare primary placental neoplasm, with only five cases reported in the literature (Table 1). Some researchers considered it as a bona fide chorangiocarcinoma, but most cases described a chorangioma with abnormal trophoblastic proliferation. In spite of atypia in cytology, marked mitosis and tumor necrosis, chorangiocarcinoma was always reported benign. No metas...

BACKGROUND: Placental site trophoblastic tumor (PSTT) is a rare and unique form of gestational trophoblastic disease (GTD). This tumor represents a neoplastic transformation of intermediate trophoblastic cells. We document a case of long term remission in a patient with metastatic PSTT. CASE PRESENTAION: A 27-year-old patient with metastatic PSTT was treated with combination therapy (chemothera...

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...

An epithelioid trophoblastic tumor (ETT) is a form of gestational trophoblastic neoplasms that arise from trophoblasts. The tumor generally occurs in women of reproductive age and has a characteristic growth pattern and immunohistochemical profile. We present an extremely rare case of a primary ETT occurring in the lungs with an adenocarcinoma in the contralateral lung as synchronous double pri...

An epithelioid trophoblastic tumor (ETT) is a rare trophoblastic tumor originating from chorionic-type intermediate trophoblasts. Vaginal involvement in ETT in the form of isolated lesions has not been previously reported. A 43-year-old woman presented with vaginal wall cysts and was diagnosed with ETT by pathological examination after cystectomy. No clinical evidence of uterine involvement was...

Choriocarcinoma is an aggressive malignant disease that originates in the trophoblastic cells of the placenta, characterized by early hematogenous spread to the lungs. It belongs to the far spectrum of gestational trophoblastic disease (GTD), a subset of germ cell tumor. It is a hypervascular tumor composed of sheets of malignant cytotrophoblast and syncytiotrophoblast metastasizing hematogenou...

Invasive mole also known as chorioadenoma destruens comprises about 15 % of all gestational trophoblastic neoplasia [1]. It is a trophoblastic tumor characterized by myometrial invasion by direct extension or through venous channels. The most common presenting symptom is vaginal bleeding (97 %) [2]. The diagnosis is usually suggested after a hydatidiform mole is removed and bhCG remains elevate...
