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.

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. 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.

Abstract Background We investigated the incidence of endometriosis in women with mature cystic ovarian teratoma and analyzed the clinicopathologic features of this occurrence. Methods From January 2017 through December 2018, we retrospectively studied 71 women who had undergone cystectomy for mature cystic ovarian teratoma (n = 55, teratoma group) and coexistence of endometriosis and mature cystic ovarian teratoma (n = 16, complex group). Serum anti-Müllerian hormone (AMH) levels were measured preoperatively and one month after surgery. Results Sixteen (22.54%) patients had coexistence of endometriosis and mature cystic ovarian teratoma (complex group); 55 patients had mature cystic teratoma alone (teratoma group). Early-stage endometriosis (stage I) was present in eight patients and advanced-stage endometriosis (stage III or IV) was present in eight. In five cases (31.25%), the coexistence of endometrioma and mature cystic teratoma in the same ovary was observed. The mean operation time was significantly shorter in the teratoma group than in the complex group (61.02 ± 22.74 vs. 86.31 ± 35.35 min, p = 0.007). The complex group had more dysmenorrhea (43.8% vs. 7.3%, p = 0.002) and a significantly higher rate of decrease in serum anti-Müllerian hormone (AMH) levels (33.06 ± 24.92 vs. 16.31 ± 28.17%, p = 0.048). Conclusion(s) The prevalence of coexisting endometriosis and mature cystic ovarian teratoma may be underestimated. Patients with this rare concurrence may present with worsening dysmenorrhea and damage to ovarian reserve after surgery may be greater in patients with coexisting endometriosis than in patients with mature cystic teratoma alone.

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.

Introduction. Malignant transformation in a mature cystic teratoma of the ovary is a rare complication. Squamous cell carcinoma is the most common transformation. We describe a new case of squamous cell carcinoma arising in a mature cystic teratoma.Case Report. A premenopausal 52-year-old female patient is diagnosed with vaginal bleeding. According to examination made on the women and the pelvic scanning, 7 cm mass is found on the right adnexa of the patient. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic lymph node dissection, and debulking were the treatments completed on the patient. According to histopathological diagnosis, squamous cell carcinoma arising in a mature cystic teratoma is diagnosed as a reason for the mass in the right adnexa of the patient.Conclusion. The prognosis of the malign transformation of MCT depends on surgery stage; however it is extremely poor. The patient should receive chemotherapy regardless of stage. We have decided to administer second cycle carboplatin and paclitaxel treatments on the patient.

Introduction. Coexistence of carcinoid tumor inside a mature cystic teratoma is an extremely rare phenomenon, especially in young women. We present the case of a 28-year-old woman diagnosed with a right ovarian carcinoid and treated uneventfully with conservative surgical approach.Case Report. A 28-year-old woman, gravid 0, parity 0, presented to our department for her annual gynecological examination and Pap smear test. During her examination, a mobile cystic mass was detected in the right lower abdomen. Ultrasound indicated a right ovarian mass 10.5 × 6.3 cm, confirmed by CT scan. Further investigation revealed AFP levels (1539 ng/mL). The ovarian mass was excised by laparoscopy, leaving intact the remaining right ovary. Frozen sections showed a mature cystic teratoma. However, paraffin sections revealed the presence of a small carcinoid within the teratoma’s gastric-type mucosa. The patient was set to a close followup. Nine months postoperatively, ultrasound pelvis imaging and CT scan of the abdomen as well as serum tumor markers have shown no evidence of recurrence disease.Conclusion. Despite the weak evidence, fertility spare surgical approach for women wanting to preserve their genital tract might be a reasonable option.

Abstract Mature cystic teratoma or dermoid cyst is the most common germ cell tumour of the ovary. The incidence ranges from 5 to 25% of all ovarian neoplasms out of which 13.7% are bilateral. Teratomas usually occur in the ovaries but they may be seen in other sites known as extragonadal teratomas the incidence of which is only 0.4%. Teratomas are usually benign but they may turn out to be highly malignant. Torsion is known to be the most frequent complication of ovarian teratomas followed by autoamputation. Teratomas are classified as “Mature” and “Immature” by WHO. Teratomas show good prognosis specially the mature ones. Surgery and follow up remains the standard approach. We report a case of mature cystic teratoma in the right ovary of a 28 years old nulliparous woman.
