BACKGROUND Malignant transformation(MT)of mature cystic teratoma(MCT)has a poor prognosis,especially in advanced cases.Concurrent chemoradiotherapy(CCRT)has an inhibitory effect on MT.CASE SUMMARY Herein,we present a case in which CCRT had a reduction effect preoperatively.A 73-year-old woman with pyelonephritis was referred to our hospital.Computed tomography revealed right hydronephrosis and a 6-cm pelvic mass.Endoscopic ultrasound-guided fine-needle biopsy(EUS-FNB)revealed squamous cell carci-noma.The patient was diagnosed with MT of MCT.Due to her poor general con-dition and renal malfunction,we selected CCRT,expecting fewer adverse effects.After CCRT,her performance status improved,and the tumor size was reduced;surgery was performed.Five months postoperatively,the patient developed dis-semination and lymph node metastases.Palliative chemotherapy was ineffective.She died 18 months after treatment initiation.CONCLUSION EUS-FNB was useful in the diagnosis of MT of MCT;CCRT suppressed the disea-se and improved quality of life. 展开更多

Teratomas have been reported to occur in multiple organ regions, and are less common in non-gonadal regions, such as the neck and chest, than in gonadal and midline regions of the body, such as ovaries and testis. Cases have been reported of a large teratoma of the anterior mediastinum extending to the neck, causing symptoms such as dyspnea, which can be quickly detected by Ultrasound, and patients can be quickly treated. In adults, primary teratoma at the suprasternal foss that not accumulate thyroid gland upward and not invade the mediastinum are rare, usually have no obvious clinical symptoms and are found in most patients by chance. In this literature, we report a rare case of mature cystic teratoma in the suprasternal fossa of a 33-year-old male. Preoperative ultrasonography showed a superior sternal fossa tumor with less calcification and more adipose tissue. The final pathologic diagnosis was mature cystic teratoma through open surgery of the suprasternal neck incision. The patient was followed up for 9 months and there was no recurrence. We believe that the suprasternal notch approach is a safe and effective method for the treatment of mature teratoma without protruding into the superior mediastinum. 展开更多

Objective To report a case of benign mature cystic teratoma of fallopian tube along with endometrial ovarian cyst, occasionally found during the operation. Methods A 30-year-old patient complained of mild dysmenorrhea and gradual enlargement of bilateral adnexal cysts in the past one year. At the age of 27 she had undergone a laparoscopic right ovarian endometrial cyst ablation. Before the second operation, pelvic ultrasound revealed recurrence of bilateral cysts in the adnexal regions, as well as serum concentrations of CA19-9 and CA125 above normal limits. Laparotomy revealed a 7 cm cystic mass of the right ovary, tightly adhesive to the lateral pelvic; a 10 cm-large mass on the left adnexal region embedded among intestines. The left adnexal mass appeared to be attached to the fimbriated end of the left fallopian tube with the ipsi-lateral ovary. However the left fallopian tube was obscure because of severe synechia. After separating the adhesion, we found the left hydrosalpinx. Results During laparotomy, both the cyst on the right ovary and the left fallopian tube were removed. Grossly, it revealed enlargement of the left fallopian tube in diameter 1.3 cm, with 2 neoplasms, in diameter 0.6 cm and off-white and smooth appearance. This mass was considered to be a mature solid teratoma arising in the left fallopian tube. At the same time it indicated left hydrosalpinx. Conclusion Although mature cystic teratomas are derived from ovarian germ cells (in proportion of 16%-20%), mature teratoma of the fallopian tube is very rare. Once diagnosis, the operation will be recommended. This case was revealed during the laparotomy accidentally. The prognosis was good. 展开更多

Objective To study the incidence of malignant change, diagnosis and management of mature cystic teratomas in postmenopausal women.Methods Twenty cases of mature cystic teratoma in postmenopausal women admitted to our hospital between January 1977 and January 1997 was retrospectively reviewed and evaluated.Results The number of postmenopausal patients with mature cystic teratoma (20) accounted for 7.6% of the total number of patients with benign ovarian teratomas (263). There were 3 cases of malignant change, which were squamous carcinoma, carcinosarcoma, and digestive gland epithelial carcinoma. The incidence of malignant change was 15%.Conclusion In postmenopausal women, mature ovarian cystic teratoma should be treated as lowly malignant and should be paid much attention. 展开更多
