Strumal Carcinoid

Primary ovarian carcinoid tumors are extremely rare. Ovarian strumal carcinoid is usually derived from mature cystic teratoma, an ovarian germ cell tumor composed of two distinctive components characteristic thyroid tissue intermixed with a carcinoid tumor. The incidence of stromal carcinoid tumor is accounting for 0.3-1% of all ovarian tumors and 3% of all mature teratomas. Herein, we report a 25-year-old female presented with severe abdominal pain. She had right struma ovarii after Laparoscopic-Assisted Ovarian Cystectomy (LAOC) procedure one year ago. The sonography of abdomen images study demonstrated a well capsulated cystic mass measured up to 11 cm in dimension. The mature cystic teratoma was the first diagnostic possibility. She underwent the laparoscopy-assisted left ovarian cystectomy. Histopathological and immunohistochemical examinations confirmed strumal Carcinoid Tumor of the Ovary (SCTO) arising from strum ovarii in the left ovary. She was recovered well and was still asymptomatic after two years follow-up. In conclusion, we first describe the primary SCTO arising from a heterochronous struma ovarii. The symptoms of SCTO are usually non-specific and misleading. Therefore, it is important to fully understand the characteristics, diagnosis and management of SCTO. Diagnosis should be confirmed by pathology and immunohistochemistry, and clinically metastatic carcinoid should be excluded.

Strumal Carcinoid

Ovarian primary carcinoid tumors are very rare, accounting for 0.5-1.7% of all carcinoid tumors and 3% of ovarian teratomas. This type of tumor frequently arises from a mature cystic teratoma. The primary ovarian carcinoid tumors are divided into 4 major types, based on their histological characteristics: insular, trabecular or mucinous pattern. Strumal carcinoid refers to insular or trabecular pattern associated with struma ovarii. The strumal type is the most common histologic form, accounting for 40% of primary ovarian carcinoid tumors. Approximately 5% of carcinoid tumors of the non-mucinous type can be malignant. However, in the case of ovarian strumal carcinoid, the occurrence of metastasis is unusual. This article is based on a case of a 30-year-old nulliparous woman diagnosed with strumal carcinoid, who presented a right ovarian tumor suggestive of teratoma synchronous to a breast cancer. She was referred to our center for fertility preservation.

Introduction. Malignant transformation is a rare complication of mature cystic teratoma, with squamous cell carcinoma as the most common malignancy (in 75% of cases). In this article we present a case of a well-differentiated squamous cell carcinoma arising in a mature cystic teratoma and discuss the morphological and clinico-pathological features of malignant transformation in teratoma. Case Report. An 80-year-old woman with symptoms of acute abdomen underwent left salpingo-oophorectomy. Gross examination showed a cystic mass measuring 20 cm in diameter, with papillary formation on its internal surface. Histology revealed a well-differentiated squamous cell carcinoma arising in mature cystic teratoma. Squamous epithelium surrounding the tumor was dysplastic. Conclusion. Squamous cell carcinoma in mature cystic teratoma is a rare pathologic event and in most cases it is an accidental pathohistological finding.

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 Struma ovarii (SO) is a rare special type of monodermal teratoma of ovary that predominantly consists of thyroid tissue (> 50%). In only 5 to 20% of cases hyperthyroidism is seen due to functional SO. We are reporting here a case of unilateral benign cystic SO in a 50-year-old postmenopausal lady presented with pain and heaviness in lower abdomen without any signs and symptoms of hyperthyroidism. Pelvic ultrasonogram showed right side tubo-ovarian mass and was planned for laparotomy. In preoperative investigation subclinical hyperthyroidism was diagnosed. Abdominal exploration showed cystic mass lesion in right ovary. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy. Histopathological examination diagnosed the mass as benign cystic SO. Patient became euthyroid after surgical removal of tumor. How to cite this article Lata I, Kapoor D.
