Malignant degeneration of mature cystic teratoma of the ovary with small bowel metastasis incidental serous cystadenoma collision tumor of the right ovary

A 30-year-old woman (gravida 0) visited our hospital with a complaint of right lower abdominal pain. Transvaginal ultrasonography revealed a 5-cm swollen right ovary, which was suspected to be a mature cystic teratoma. Pelvic examination revealed moderate pain. Contrast-enhanced computed tomography showed a 44-mm cystic mass containing fat and calcified material in the right pelvis. Since torsion was suspected, emergent laparoscopic surgery was performed. Intraoperative findings were a swollen right ovary without torsion or congestion. Two small pedunculated 1- and 2-cm diameter paratubal cysts that grew from almost the same place of the ampulla of the right fallopian tube were observed. The thin stalk of the 1-cm paratubal cyst was entangled around the stalk of the 2-cm paratubal cyst, with its head congested. Through a small abdominal laparoscopic incision, the tumor of the right ovary and the two paratubal cysts were excised. Histopathological examination revealed that the right ovarian tumor was a mature cystic teratoma, and the two paratubal cysts had no malignancy. This case showed that only a 2-cm tumor with congestion caused the acute abdomen.

Background: Ovarian cystic neoplasms are common in gynaecological practice. These may pose diagnostic difficulty to the pathologists. This study was conducted to analyse the clinical and histological profile of ovarian cystic neoplasms.Methods: This is a retrospective study done from January 2016 to April 2017 in a tertiary care hospital in North East India. All the patients, who were clinically and radiologically diagnosed as ovarian cysts, which had histopathological confirmation were included in the study. Data including the age, parity, clinical symptoms, laterality and histopathological findings were analysed.Results: A total of 101 patients operated for ovarian cysts in the study period were analysed. The most common clinical presentation was lower abdominal pain. There were 11 (10.9%) malignant cases, 4 (4%) were intermediate grade and borderline in nature, and 85 (84.1%) cases were benign in nature. There was 1 (1%) case of metastasis to ovary. Mature cystic teratoma was most common (20.8%) histopathological diagnosis. The second most common cyst was serous cystadenoma (19.8%).Conclusion: Ovarian cysts are commonly encountered in gynaecological practice and equally encountered by the pathologists. Most commonly found ovarian cysts were mature cystic teratoma followed by serous cystadenoma.

Background. Mature cystic teratomas of the fallopian tube are extremely rare and only 54 cases have been reported in the literature. In this paper, we report a mature cystic teratoma of the fallopian tube in a postmenopausal woman and we report the review of literature of tubal cystic teratomas.Case. A 62-year-old, gravida 4 postmenopausal woman presented with pain in the right lower abdominal region for a long time. An 88 × 72 × 95 mm heterogeneous mass which contained calcifications and lipoid components was detected in the right adnexal region by transvaginal ultrasonogram (TV-USG). Serum tumour markers, namely, CA125, CA15-3, and CA19-9, were within normal range. A laparotomy revealed a 9 × 10 cm cystic mass within the fimbrial region in the right fallopian tube, and right salpingoopherectomy was performed consequently. Microscopic examination revealed squamous epithelium with sebaceous glands and hair follicles, and pseudostratified ciliated respiratory epithelium with cartilage and mucous glands. Because the frozen section resulted in a benign dermoid cyst, no further operative procedure was performed. The postoperative follow-up was uneventful and the patient was discharged on the second postoperative day.Conclusion. In cases of undetermined pelvic or abdominal masses, a teratoma of the fallopian tube should be considered.

Case Presentation

Abstract Background: Collision tumor is a clinically rare disease, it is defined as two or more primary tumors from different tissues occurring at the same anatomical site. Ovarian collision tumor is more rare. Case presentation: A patient was hospitalized with a pelvic mass. The CA125 level was 53.46U per milli liter (normal range, 0 to 30u/ml). Another patient was hospitalized with lower abdominal pain and no apparent hormonal abnormalities. Ovarian lesions were found in both patients after examination, and postoperative pathology showed that both patients were ovarian collision tumors. Conclusion: Collision tumor composed of mature cystic teratoma, follicular membranous cell tumor and serous cystadenoma was first reported. The biological behavior of collision tumor is different due to its different components. Accurate diagnosis is of great significance to treatment.

Adenomatoid tumor of the ovary is rare, and so are collision tumors in this location. The most common histological combination of ovarian collision tumors is the coexistence of mature cystic teratoma with ovarian cystadenoma or cystadenocarcinoma. Presented herein is a rare case of ovarian adenomatoid tumor found incidentally and coexisting with mature cystic teratoma. A 44-year-old woman presented with a one-year history of intermittent right-sided pelvic pain. Ultrasound evaluation revealed a heterogeneous cystic mass in the right ovary, and a clinical diagnosis of teratoma was made. The patient subsequently underwent a right salpingo-oophorectomy. Pathological examination revealed a mature cystic teratoma and coexistent adenomatoid tumor. The two tumors were separate and no transitional features were recognized histologically. To our knowledge, no previous report of coexistence of these two tumors has been reported. Both tumors are benign and completely excised; therefore no adverse consequences are expected.

Anti-NMDAR (N-methyl-D-aspartate receptor) encephalitis is an immune-mediated encephalitis. It has been predominantly described in young women and is commonly associated with an ovarian teratoma. We report a case of anti-NMDAR encephalitis associated with a 7 mm ovarian teratoma that was completely resected by laparoscopic surgery. An 18-year-old woman suddenly presented with personality changes requiring her admission to the department of neurology. After that, she also showed involuntary movements, disturbance of consciousness, and central hypoventilation. As an abdominal image revealed the possibility of a right ovarian teratoma of5×7 mm, a laparoscopic operation was performed. The macroscopic appearance of the right ovary did not show any abnormalities; nevertheless, we performed a partial resection of the right ovary, with reference to the image diagnosis, in order to spare the ovarian reserve. The22×22 mm partially resected ovary contained an intact5×7 mm cystic tumor. The pathological diagnosis was mature cystic teratoma with components of brain tissue. An anti-NMDAR-antibody test proved positive in both serum and cerebrospinal fluid 1 month after the surgery. From these results, she was diagnosed with anti-NMDAR encephalitis. By the administration of cyclophosphamide in addition to the operation, she recovered drastically without any of the symptoms shown before.

Objectives. The study was conducted to characterize the use of the laparoscopic surgery in elderly patients. Methods. The medical records of elderly patients aged ≥65 years who underwent laparoscopic surgery were retrospectively reviewed for diseases, surgical procedures, histological diagnosis, intraoperative and postoperative complications, and reasons for presentation. Results. Of the 405 patients who underwent laparoscopic surgery between January 2005 and March 2012, 41 (10.1%) were aged ≥65 years. The most common disease treated by surgery was ovarian tumor, followed by uterine prolapse. Histological diagnosis of ovarian tumor specimens obtained from 23 patients included serous cystadenoma (44.0%), mature cystic teratoma (20.0%), mucinous cystadenoma (20.0%), and endometrioma (4%). In contrast, in the non-elderly group, the most common histological diagnosis was endometrioma (42.9%), followed in order by mature cystic teratoma (28.3%), serous cystadenoma (18.0%), and mucinous cystadenoma (4.7%). While 23.7% of the non-elderly patients required emergency laparoscopic surgery, none of the elderly patients required emergency surgery. Only 1 of 27 patients who underwent surgery for an ovarian or adnexal mass presented with abdominal pain. No one developed serious intraoperative or postoperative complications. Conclusion. Laparoscopic surgery can be safely performed in elderly patients. It should be noted, however, that few elderly patients with benign pelvic mass manifest symptoms before undergoing surgery.

This research was a cross sectional analytic observational histopathological study of cystic ovarian lesions carried out over three years from March, 2012 to February, 2015 at Chitwan Medical College Teaching Hospital in Nepal. The objective of this study was to study cystic ovarian masses histopathologically. A total of one hundred and fourteen patients with cystic ovarian masses were included into the study. 46.5% lesions were non-neoplastic (83% physiologic and 17% pathologic) and 53.5% lesions were neoplastic (91.8% benign and 8.2% malignant). Follicular cyst was the most common ovarian cystic lesion overall, followed by mature cystic teratoma and serous cystadenoma. 14.9% of all the ovarian cysts had undergone torsion; among them mature cystic teratoma was the most common lesion to have undergone the complication. Neoplastic ovarian cysts were more common than non-neoplastic. Follicular cyst was the most common ovarian cyst overall. Mature cystic teratoma was the ovarian cystic lesion to be affected by torsion most commonly.
