Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic neoplasm composed of intermediate trophoblasts. Most cases of ETT are reported in women of reproductive age following a prior gestation within 2 weeks to 30 years. ETT is extremely rare in postmenopausal women. It is commonly misdiagnosed as a poorly differentiated carcinoma or another type of gestational trophoblastic tu...

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...

Trophoblastic diseases are mainly hydatidiform mole and choriocarcinoma, where the latter is usually the sequela of molar pregnancy and malignant systemic disease with general metastases destructing various tissues and organs till she die. High level urinary hCG, real-time B-mode and color Doppler imaging detect hydatidiform mole in early gestation, postmolar persistent trophoblastic disease is...

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...

Epithelioid trophoblastic tumor is an unusual type of trophoblastic tumor. Here we report on the clinicopathologic and immunohistochemical features of three cases of epithelioid trophoblastic tumor. All three patients were of reproductive age and presented with vaginal bleeding and mild elevation of human chorionic gonadotropin (hCG). All patients underwent a hysterectomy. The tumors consisted ...

Epithelioid trophoblastic tumor (ETT) is a very rare variant of gestational trophoblastic disease (GTD) which arises in reproductive age women with prior gestational history. Although abnormal vaginal bleeding is the most common symptom of ETT, there are no reported pathognomonic symptoms of ETT because of its rarity. ETT is similar to placental site trophoblastic tumor in terms of its slow gro...

Gestational trophoblastic neoplasms are malignant lesions that arise from placental villous and extravillous trophoblast. Four clinicopathologic conditions make up this entity: invasive mole (IM), choriocarcinoma (CCA), placental-site trophoblastic tumor (PSTT), and epithelioid trophoblastic tumor (ETT). IM and CCA, which make up the majority of these tumors, are highly responsive to chemothera...

Gestational trophoblastic neoplasia (GTN) includes invasive mole, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. The overall cure rate in treating these tumors is currently >90%. Thorough evaluation and staging allow selection of appropriate therapy that maximizes chances for cure while minimizing toxicity. Nonmetastatic (stage I) and low-risk metastat...

Gestational trophoblastic neoplasia (GTN) is the term to describe a set of malignant placental diseases, including invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor. Both invasive mole and choriocarcinoma respond well to chemotherapy, and cure rates are greater than 90%. Since the advent of chemotherapy, low-risk GTN has been treated with a s...
