Epithelioid trophoblastic tumor of the lower uterine segment and cervical canal:A case report

BACKGROUND Epithelioid trophoblastic tumor(ETT) is the rarest type of gestational trophoblastic tumor(GTT). It has been reported that more than 50% of ETTs arise in the uterine cervix or the lower uterine segment. Here, we report a case of ETT within the lower uterine segment and cervical canal and discuss its manifestations,possible causes, and related influencing factors.CASE SUMMARY A 35-year-old woman(gravida 7, miscarriage 3, induction 2 with 1 being twins,para 2 of cesarean section, live 2), who had amenorrhea for 9 mo after breastfeeding for 22 mo after the last cesarean section, was diagnosed with ETT. The lesion was present in the lower uterine segment and endocervical canal with severe involvement of the anterior wall of the lower uterine segment and the front wall of the lower uterine segment where the cesarean incisions were made.Laboratory tests showed slight elevation of serum beta-human chorionic gonadotropin. Intraoperative exploration showed the presence of a normal-sized uterus body with an enlarged tumor in the lower uterine segment. The surface of the lower uterine segment was light blue, the entire lesion was approximately about 8cm × 8 cm × 9 cm, with compression and displacement of the surrounding tissue.Histological examination diagnosed ETT. Immunohistochemical analysis showed positive expression of p63, with a Ki-67 proliferation index of 40%.CONCLUSION A search of the PubMed database using the search terms "cesarean section" and "epithelioid trophoblastic tumor" retrieved nine articles, including 13 cases of ETT and ETT-related lesions, all 13 cases had a history of cesarean section, and the lesions were all located at the cesarean section incision on the anterior wall of the lower uterine segment. The present case is the 14th reported case of ETT after cesarean section. Therefore, we deduced that cesarean section trauma had an important effect on the occurrence of ETT at this site.

DIAGNOSIS AND TREATMENT OF THE MALIGNANT GESTATIONAL TROPHOBLASTIC TUMOR WITH PULMONARY METASTASIS COMPLICATED WITH PULMONARY TUBERCULOSIS

Objective. To evaluate the diagnosis and treatment for malignant gestational trophoblastic tumor(MGTT) with pulmonary metastasis complicated with pulmonary tuberculosis. Methods. To analyze ten cases of MGTT with pulmonary metastasis complicated with pulmonary tuberculosis in our hospital from 1980 to 1997 retrospectively. Results.From the x ray film, there are great resemblances between MGTT with pulmonary metastasis and pulmonary tuberculosis. Of 10 patients, 7 of them were examined out pulmonary tuberculosis during the chemotherapy of MGTT. Pulmonary tuberculosis appeared six months before chemotherapy in three cases. All of the patients were treated with multiagent chemotherapy. Seven patients achiceved a complete remission, 2 patients developed drug resistance and died of cerebral haemorrhage and cerebral herniation, 1 woman who had achieved a complete remission from MGTT for 14 months died of miliary tuberculosis. Conclusion. It is very important to make differential diagnosis of the MGTT with pulmonary metastasis complicated with pulmonary tuberculosis. Trying to avoid excessive anti tumor treatment owing to mistake pulmonary tuberculosis for pulmonary metastasis, and avoiding missing an opportunity of anti tuberculosis treatment because of missed diagnosis should be emphasized.

EMA/CO Regimen Chemotherapy for Gestational Trophoblastic Tumor

Objective To evaluate the efficacy and safety of etoposide, methotrexate, actinomycin D, vincristine and cyclophosphamide (EMA/CO) therapy for gestational trophoblastic tumor (GTT). Methods Medical records of all patients with low risk, middle risk and high risk GTT receiving EMA/CO regimen chemotherapy were analyzed retrospectively. Results\ Twenty one low risk and fourteen middle risk GTT received EMA/CO with 100% remission, six patients with high risk GTT received EMA/CO with 83% complete response and with 17% partial response; Gastrointestinal, hematologic and hepatic toxicity, as well as shed of hair is predictable, mild and reversible. Conclusion\ At present EMA/CO chemotherapy is the choice of our treatment for patients with high, middle and low risk GTT.\;
