Ovarian Dermoid Cysts: A Comprehensive Review
Journal of Current Clinical Care, 2024
Ovarian dermoid cysts, also known as mature cystic teratomas, are the most common benign ovarian neoplasms, accounting for approximately 20-25% of all ovarian tumors. 1 These germ cell-derived tumors typically contain mature tissue from multiple germ cell layers, including ectoderm, mesoderm, and endoderm. 2 Clinical Presentation Dermoid cysts predominantly affect women of reproductive age, with peak incidence occurring between 20-40 years. 3 The clinical presentation varies significantly: • Asymptomatic: Many dermoid cysts are discovered incidentally during routine pelvic examinations or imaging studies. 4 • Abdominal/Pelvic Pain: Patients may experience chronic or intermittent pain due to:-Mass effect on surrounding structures-Torsion (10-15% of cases)-Rupture (1-2% of cases) 5
Squamous cell carcinoma arising in a dermoid cyst of the ovary: A case series
Bangladesh Medical Research Council Bulletin
Background: Malignant transformation in a dermoid cyst of the ovary is a rare complication, occurring in only 1-2% of cases, with squamous cell carcinoma being the most common type. Preoperative diagnosis is difficult because of the lack of specific symptoms and signs to suggest malignancy. The prognosis is generally poor when disease has spread beyond the ovary. Objective: This study was conducted to review experience with this disease and describe the current treatment modality. Methods: It was identified 4 women with this diagnosis during 2013-2018. This is a descriptive study, looking at the patient’s characteristics, mode of presentation, the role of tumor markers and radiological imaging in diagnosis. It was also examined the stage and pathological features of the presentation and subsequent course of the disease. Result: The median age was 45 (range: 32-63 yrs). Three cases were stage I and one case was stage III. The average tumor diameter was 14.1cm. All patients were und...
Squamous Cell Carcinoma Arising in a Dermoid Cyst Ovary: A Rare Case Report
2016
Dermoid cysts account for approximately 25% of all ovarian tumors. Presence of pure squamous cell carcinoma is very rare findings (1-2%), which is attributable to malignant transformations into a pre-existing dermoid cyst. As there are no specific signs and symptoms to suggest malignancy in dermoid cyst, therefore it is difficult to predict, and most cases are diagnosed post-operatively. We hereby report a case of dermoid cyst ovary with malignant transformation into squamous cell carcinoma in 50 years post-menopausal women. Who presented with complaint of abdominal pain and increased frequency of micturation. Hysterectomy with Bilateral-salpingo-oophorectomy (BSO) with omentectomy was done. Right ovary showed huge cyst with hair shaft, sebaceous materials and a small solid area. Histopathological examination revealed squamous cell carcinoma was arising within the dermoid cyst.
Laparoscopic Management of Ovarian Dermoid Cyst in a 31-year-old Woman: A Case Report
World Journal of Laparoscopic Surgery, 2021
Ovarian dermoid cysts, also known as mature teratomas, are one of the ovarian numbers that can develop into malignancy and are mostly found in women aged 20-40 years. Most cases of teratoma mature cystic were discovered accidentally through the imaging examination. We reported a 31-year-old woman with complaints of bleeding from the birth canal for 16 days and accompanied by sharp pain during menstruation. The general condition is good and other vital signs examined were within normal limits. Abdominal ultrasound examination showed a mass in the right adnexa with a size of 12 × 10 × 8 cm and there were longitudinal thin white lines. Laparoscopic right ovarian oophorectomy was performed. After removing the mass was opened and there was a lot of hair in it. There are no complications during surgery and after surgery. The results of the histopathological examination were by the dermoid cyst.

Mature cystic teratoma (MCT) is the most common tumour of the ovary and includes at least two well-differentiated germ cell layers. The incidence is higher in reproductive age group and rarely among postmenopausal age women. It is benign condition however associated with multiple complication such as torsion, ruptured and chemical peritonitis. As it is rare among postmenopausal age group, it can be presented as chronic ovarian mass with expected complication and possibility of malignant transformation. Thorough assessment with adjunct of radiological imaging may assist in diagnosis and further management. Radiological imaging modalities were sensitive and sensitive in diagnosis of MCT however there were low specificity in detection of complication. Management of MCT in postmenopausal women mandate thorough evaluation considering the risk of malignant transformation and associated complications.

Dermoid Cyst and its bizarre presentation
Journal of Nepal Medical Association
Dermoid cysts or mature cystic teratoma are the most common type of ovarian germ cell tumor usually occurring in the reproductive age group. They are commonly unilateral and 10-12 % can be bilateral. They are commonly multicystic and contain sebaceous fluid as well as tissue of three germ cell layers e.g. ectoderm (skin, hair, brain) mesoderm (muscle, fat ,teeth ,bone, and cartilage) and endoderm (mucious and ciliated epithelium).These teratomas usually arise from the gonads but has been found anywhere in the body. Their site, size and clinical presentations are extremely variable causing confusion with medical and surgical diseases, acute emergency due to rupture and torsion , bowel and bladder injuries, and pregnancy etc. The malignant teratoma occurs at 3-4% only among ovarian carcinoma. The malignant transformation in benign cysts is a rare occurrence with 1-2% cases and squamous cell carcinoma being the commonest. This review is undertaken to study the different presentations p...
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.

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...
Cecal dermoid masquerading dermoid cyst of ovary: a case report and review of the literature
Journal of Medical Case Reports
Background The ovary is the most common site of occurrence of mature cystic teratomas (dermoid cysts). These are the most common ovarian germ cell tumor in the reproductive age group, accounting for 10–20% of all ovarian neoplasms, with a 1–2% risk of malignancy. A cecal dermoid cyst is a rare entity with only ten cases having been reported so far, eight of which could be retrieved as the rest were reported in different languages. None of these cases were managed laparoscopically. Here we present the first case of cecal dermoid managed laparoscopically. Case presentation A 35-year-old nulliparous Indian Hindu woman presented with complaints of on and off abdominal pain for 10 months. The abdominal examination revealed a well-defined mass of about 10 × 5 cm size, palpable in the right iliac fossa. On sonography, it was suggestive of a right-sided ovarian dermoid cyst. The lesion measured 10 × 7 × 5 cm on a contrast-enhanced computed tomogram (CT) scan. It was well defined and hypoden...
Subtle Presentation of Bilateral Ovarian Dermoid Cysts With Unilateral Torsion: A Case Report
Journal of Clinical Gynecology and Obstetrics, 2015
Majority of non-physiological tumors seen in pregnancy are mature cystic teratomas, also known as dermoid cysts. Their discovery in pregnant women poses a vexing problem as there are no established guidelines for their management and multiple factors need to be considered to decide the appropriate strategy. We are reporting a case of bilateral ovarian dermoid cysts in a pregnant woman who presented towards the end of her third trimester and was managed by careful observation until the day of elective cesarean section and bilateral cystectomy. During surgery the team was surprised to discover a torsed dermoid cyst. The striking features of this case were the subtlety of clinical presentation and the absence of typical signs associated with ovarian torsion.
