OBJECTIVE: Mature cystic teratoma, also known as a dermoid cyst, is the most common germ cell tumor of the ovary. In this retrospective study, it is aimed to evaluate clinicopathological findings of the patients who were operated on due to the preliminary diagnosis of dermoid cyst. STUDY DESIGN: Between May 2013 and May 2018, the findings of a total of 143 patients who were operated on with a preliminary diagnosis of dermoid cyst in our institution were analyzed retrospectively. In addition to demographic characteristics such as age, parity number and tumor size, lateralization, preoperative tumor markers, surgical procedure, presence of other pathological findings, and the rate of malignant transformation were analyzed. RESULTS: The median age of patients was 35.4 years and the ratio of nulliparous, primiparous, and multiparous patients was 46.9%, 25.2%, and 28%, respectively. The median tumor diameter was 6.7 cm, 50.3% of which were right-sided, 46.9% were left-sided and the remai...
Ovarian tumor with mature teratoma with squamous differentiation in a postmenopausal female
International Journal of Reproduction, Contraception, Obstetrics and Gynecology, 2017
Mature cystic ovarian teratomas are the commonest germ cell tumour accounting for about 30-45% of all ovarian neoplasms and around 60% of all benign tumors arising in the ovary. The reported incidence of malignant transformation in MCT is approximately 2%. A rare case of squamous cell carcinoma arising in a dermoid cyst of the ovary presenting in a postmenopausal female is presented here. A 60-year-old postmenopausal lady, presented with the complaint of pain in lower abdomen for 2 years and a large complex abdomino-pelvic mass on examination and investigations. Final histopathology was reported as squamous cell carcinoma arising from mature cystic teratoma of right ovary. Primary cytoreductive surgery was done and a surgical stage IIB was assigned. In view of the poor prognosis, adjuvant chemotherapy was started.
Malignant degeneration of cystic teratoma of the ovary: two cases report
International Journal of Reproduction, Contraception, Obstetrics and Gynecology, 2020
The malignant degeneration of mature ovarian teratomas is a rare phenomenon. Case reported two cases of squamous cell carcinoma developed on mature teratoma of the ovary in patients aged 54 and 41 who were seen for chronic pelvic pain. Their pelvic ultrasound showed cystic double-component images with sizes of 103 and 95 mm respectively suggestive of dermoid cysts, and the anatomopathological study of the pieces of adnexectomy confirmed the diagnosis. Although no clinical, radiological or biological signs are specific, ovarian dermal cyst degeneration is suspected in the presence of a large dermoid cyst in a postmenopausal or peri-menopausal woman. The careful anatomo-pathological study of the cyst in this case makes it possible to pose the diagnosis of certainty. A rare complication of the dermoid cyst, its prognosis is pejorative and depends mainly on its clinical stage at the time of diagnosis and the quality of its surgical treatment which must be as radical as possible.
Malignancy in mature cystic teratoma of the ovary: A rarity
Obsgyne Review: Journal of Obstetric and Gynecology, 2017
Mature cystic teratomas (MCTs) are the most commonly seen germ cell tumors of the ovaries. In postmenopausal women, they mostly undergo malignant. The most commonly seen malignancy in these type of germ cell tumors is squamous cell carcinoma of the ovary. An 83-year-old postmenopausal woman presented to us with a similar but rare clinical course that is discussed here.
Ovarian Cystectomy for Huge Mature Cystic Teratoma Developed in Less than Five Years: A Case Report
Gynecology and Obstetrics Research - Open Journal, 2016
BACKGROUND Cystic ovarian teratomas, also known as dermoid cysts, are the most common benign ovarian germ cell tumors. They typically occur during reproductive age. Due to the readable accessibility to ultrasonography, the finding of large cystic teratomas over 10 cm is an unusual event. We report a huge mature ovarian cystic teratoma developed in less than five years and was successfully treated by cystectomy.
Ovarian Teratoma in Routine Biopsy Material During a Five-Year Period
Acta clinica Croatica, 2016
Teratomas are tumors derived from germ cells, most frequently arising in the gonads. The aim of this study was to determine the number of ovarian teratomas diagnosed in the routine biopsy material at Ljudevit Jurak Clinical Department of Pathology, Sestre milosrdnice University Hospital Center during a 5-year period, as well as their clinical, gross and microscopic characteristics. Teratomas accounted for 48.6% (n=166) of primary ovarian tumors. The patient mean age was 34.74±12.37 years. Difference in the incidence of teratoma between the left and right ovary was not significant; bilateral teratoma was found in 13 patients. Teratomas were detected by ultrasonography in 115 (69.27%) cases and the rest were found during surgery performed for other indications. Most teratomas (n=161; 96.9%) were mature and cystic (dermoid cysts). Mature and solid teratomas were diagnosed in 5 (3.01%), ovarian struma in 2 (1.8%) cases and strumal carcinoid in 1 (1.2%) case. Mature cystic teratomas cont...
Mature cystic teratomas in our series with review of the literature and retrospective analysis
Archives of Gynecology and Obstetrics, 2011
Purpose Mature cystic teratomas are the most common benign ovarian neoplasms. Our aim is to analyse these cases by pathologic and clinical findings in our centre with the view of updated knowledge. Materials and methods In our study, 50 case reports diagnosed as mature cystic teratoma (or dermoid cyst) in Mustafa Kemal University Pathology Laboratory between 2005 and 2010 have been reviewed. Results Of 50 cases, the findings on mature cystic teratomas were as follows: the number of tumours located at the right ovary was 22, the left ovary, 23, with 5 cases bilaterally. Age range was 14-58 with mean rate 35.4. In two cases, tumour markers were high, one case presented with torsion; one case was obtained incidentally during delivery. Conclusion Mature cystic teratomas are benign neoplasms with low malign transformation rate. Our series are low in number but our findings show the dynamic nature of these tumours.
Mature teratoma of bilateral ovary: A case report
Medical Science
Women's ovarian tumors are a prevalent type of neoplasm. The most prevalent kind is mature cystic teratoma, which has an 8-15 % bilateral frequency. However, only a few cases of bilateral and multiple sclerosis have been described. A 42-year-old female patient with stomach pain for one day arrived with an unusual case of bilateral multiple dermoid cysts. Her medical history had been relatively normal. The patient had clots passing in the menses. Multiple bilateral ovarian cystic tumors were discovered on ultrasonography. Laparotomy was performed on the patient. The lumps were removed while the remaining ovarian tissue was preserved. In histology, the myometrium is unremarkable. In histology, a cervix segment revealed chronic cervicitis with a Nabothian Cyst. A section of the right ovary revealed characteristics that pointed to a benign cystic teratoma of the right ovary (Dermoid cyst). Histopathology of the left fallopian tube revealed endometriosis. Histopathology confirmed multiple mature cystic teratomas with no signs of malignant cells.

Mature cystic teratomas (MCT), also known as dermoid cysts, are the most common ovarian germ cell tumors and the most common ovarian neoplasms in patients younger than 20 years. Malignant transformation (MT) is a rare complication of MCTs which may occur in 1-2% of the cases. Squamous cell carcinoma (SCC) is the most frequent histology arising from MCTs and its appearance depends on diverse risk factors such as patient's age, the size of the tumor and levels of serum tumor markers. Diagnosis and treatment constitute a big challenge due to the rarity and the aggressive course of this entity. Adjuvant chemotherapy has a leading role in the treatment of MCT-arising SCC, while the use of radiotherapy or chemoradiation is still under consideration. Herein, we report a case of a post-menopausal woman, presenting with mild symptoms and a large pelvic mass deriving from the left ovary occurring as dermoid cyst. Simultaneously, we review the literature stressing out the prognostic factors and the treatment options for MCT arising SCC according to traditional and new therapy-strategies.
