Primary pulmonary Epithelioid Trophoblastic tumor co-existing with Choriocarcinoma / Philippine Journal of Obstetrics and Gynecology

@#A 28-year old, G5P4 (4014), noted neck lymph nodes associated with cough. A chest X-ray was done showing a left nodular opacity. Antibiotics were prescribed with a resolution of symptoms. Five months after, a routine chest X-ray revealed interval progression in size of the lung nodule. A chest computed tomography (CT) scan and positron-emission tomography scan were done subsequently showing the precise location and size of the nodule and with no other focus of tumor seen. Transvaginal ultrasound was normal. With an initial diagnosis of lung carcinoma, a percutaneous needle aspiration biopsy under CT scan guidance was done. Immunohistochemical staining panel showed that beta-human chorionic gonadotropin (hCG) was positive. Subsequently, a serum beta-hCG done showed low levels from 33.48 to 59.7 mIU/ml. The final diagnosis given was a poorly differentiated malignancy highly suggestive of malignant trophoblastic tumor. A video-assisted left upper lobectomy was performed with histopathology and immunohistochemistry consistent with epithelioid trophoblastic tumor with co-existing choriocarcinoma elements. Postoperative beta-hCG level dropped to normal and remained so for 2½ years.

Epithelioid trophoblastic tumor in a postmenopausal woman: A case report and review of the literature in the postmenopausal group

Epithelioid trophoblastic tumor is a rare gestational trophoblastic neoplasm arising from the intermediate trophoblasts. Although usually seen in the reproductive period, it may be encountered during the postmenopausal period. A 56-year-old woman who had given her last birth 21 years ago presented to the hospital with a complaint of postmenopausal bleeding. She had a history of eight live pregnancies and had been in menopause for 4 years. With the help of typical histopathologic and immunohistochemical findings, a diagnosis of “epithelioid trophoblastic tumor” was made. The diagnosis was made at an advanced age and the case had extraordinary features such as high mitotic activity and Ki-67 proliferation index (70%). Gestational trophoblastic neoplasms are rare causes of postmenopausal bleeding which may cause differential diagnosis problem. They should be kept in mind even if the patient age does not comply with because of the differences in treatment.

A rare case of Epithelioid Trophoblastic tumor: An ultrasound dilemma / Philippine Journal of Obstetrics and Gynecology

@#Gestational trophoblastic neoplasia (GTN) represents the malignant end of the gestational trophoblastic disease spectrum and includes the more common types, invasive mole (IM) and choriocarcinoma (CC) and the rare types, placental site trophoblastic tumor (PSTT) and epithelioid trophoblastic tumor (ETT). This is a case of a 42-year-old, G2P2 (2002) patient who complained of left lower quadrant pain and a 1 year history of amenorrhea. Urine pregnancy test done just prior to the surgery revealed positive result. Pre-operative diagnosis was abdominopelvic mass mass probably Sarcoma, ovarian new growth probably benign, right. Patient underwent exploratory laparotomy, adhesiolysis, bilateral internal iliac artery ligation, total hysterectomy with bilateral salpingo-oophorectomy, targeted biopsy, appendectomy, JP drain insertion under epidural anesthesia. Final histopathologic and immunohistochemical diagnosis is Epithelioid Trophoblastic Tumor. Differential diagnoses, diagnostics, and therapeutic options are presented, with focus on the description of sonographic features.

Extrauterine epithelioid trophoblastic tumor in hysterectomized woman

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 growing characteristic and microscopic findings. Therefore, it could be misdiagnosed as placental site trophoblastic tumor or other types of GTD. Unlike other types of GTD, primary treatment of ETT is surgical resection because of its chemo-resistant nature. Accordingly, immunohistochemical staining is essential for accurate diagnosis and appropriate treatment. Here, we report a case of a 42-year-old hysterectomized woman with pelvic masses who suffered from abdominal pain. Through laparotomy, tumors were resected completely and they were diagnosed as ETT through immunohistochemical stain. This report provides more evidence about its clinical features, diagnosis, and treatment including a brief review of the literature.

Epithelioid Trophoblastic Tumor in a Postmenopausal Woman: A Case Report

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 tumor. We report a case of ETT in a 56-year-old woman that developed 23 years after the patient's last pregnancy.

Epithelioid trophoblastic tumor: a case report of a rare trophoblastic neoplasm.

Epithelioid Trophoblastic Tumor (ETT) is a rare neoplasm of the chorionic type intermediate trophoblastic cells. It is a neoplasm of reproductive age women and usually follows a gestational event. ETT can occur at both intra uterine and extra uterine sites and can be confused with other entities such as squamous cell carcinoma, placental site nodule, placental site trophoblastic tumor etc. Hence, proper diagnosis of this tumor is necessary to avoid unnecessary, excessive treatment as surgical treatment is considered sufficient for ETT. We present a case of ETT in a 36 year old female, who came with symptoms of pain abdomen, white discharge per vaginum and a cervical mass.

Epithelioid Trophoblastic Tumor: Clinicopathologic and Immunohistochemical Analysis of Three Cases

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 of epithelioid intermediate trophoblastic cells that were mononucleated and eosinophilic, or showed clear cytoplasm on microscopic examination. One case presented with a focal choriocarcinoma component. Immunohistochemically, the tumors displayed diffuse positivity for cytokeratin 18, E-cadherin, epidermal growth factor receptor, and p53 and focal positivity for p63 and hCG. However, expression of alpha-inhibin and placental alkaline phosphatase was almost negative. Tests for human placental lactogen and epithelial membrane antigen were also negative in all cases.

Extrauterine Epithelioid Trophoblastic Tumor of Lung in a 35-year-old Woman

Extrauterine epithelioid trophoblastic tumors constitute an extremely rare gestational trophoblastic disease. We report the case of an extrauterine trophoblastic tumor that was incidentally detected in the left lung. Squamous cell carcinoma was suspected after microscopically examining the specimen obtained upon preoperative needle biopsy. After surgery, the tumor was confirmed by microscopic findings and immunohistochemical features.

Epithelioid trophoblastic tumor: A Case Report and Review of the Literature / 대한산부인과학회잡지

Epithelioid trophoblastic tumor (ETT) is an unusual variant of gestational trophoblastic tumor that is closely related to choriocarcinoma and placental site trophoblastic tumor (PSTT) but shows different morphologic, immunohistochemical features. ETT grows in a nodular pattern compared with the infiltrative pattern of PSTT. Histologically the tumor is characterized by uniform population of mononucleate intermediate trophoblastic cells that resemble the trophoblastic cells in the chorionic laeve, so we called them "chorionic-type intermediate trophoblast". Immunohistochemically ETT was positive for cytokeratin, epithelial membrane antigen(EMA) and staining for human placental lactogen (hPL) and human chorionic gonadotrophin (hCG) was generally patchy, focal or negative whereas PSTT contained more hPL-positive cells than hCG-positive cells. ETT can behave in a malignant fashion such as distant metastasis. We experienced a case of ETT by clinical result, pathologic finding, so we report a case with brief literature review.

A Case of Epithelioid Trophoblastic Tumor / 대한부인종양콜포스코피학회잡지

We report a rare case of epithelioid trophoblastic tumor. The patient was initially thought to have endometrial carcinoma with high possibility of clear cell carcinoma on endometrial biopsy and pelvic MRI. The Pap smear showed feature of squamous cell carcinoma and was not consistent with the physical findings. The serum beta-hCG was 33.26 mIU/ml. The initial biopsy and pelvic MRI findings lead the clinicians to misdiagnose the case as a carcinoma.
