Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is an infrequently encountered entity with only a handful of cases reported till date. The possibilities in such a case are either a malignant transformation of a benign teratoma into adenocarcinoma or a collision tumor between a mature cystic teratoma and a mucinous tumour of either a primary ovarian surface epithelial-stromal origin or a secondary from a primary gastrointestinal tract tumour. The importance of distinguishing between the two entities has significant bearing on subsequent therapeutic management...

INTRODUCTION: Retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. According to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). Described in this case report is an extremely unusual patient, a woman who simultaneously had a retrorectal cyst and an ovarian serous cystadenoma in addition to a long history of misdiagnosis and multiple unsuccessful surgeries...

Mature ovarian cystic teratoma (also known as ovarian dermoid cyst) is a slow growing encapsulated tumor which contains well differentiated derivations of at least two out of three germ cell layers (i.e., ectoderm, mesoderm and endoderm). The lesion is lined by ectodermally derived squamous epithelium containing skin appendages. The cyst content commonly consists of keratin, sebaceous materials and fat. On CT images, the intracystic globules of sebum/fat could appear as multiple free floating rounde hypoattenuating nodules, giving the classical 'sack-of-marbles' appearance...

Ovarian cysts are common in the reproductive age. Pathological cysts such as endometriomas and dermoids often require surgical intervention if symptomatic. Laparoscopic cystectomy is the first line treatment for these cysts, and is associated with better pain control and less recurrence than drainage or cyst ablation procedures. There has been an emerging concern about the effect of ovarian cystectomy on ovarian reserve with some evidence of short term and long term reduction in ovarian reserve. Certain cyst characteristics (endometrioma pathology, large cyst size, bilateral presentation) are associated with greater decline in ovarian reserve after cystectomy...

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...

Introduction. Carcinosarcoma is an uncommon form of ovarian cancers, classified as being part of the group of mixed epithelial and mesenchymal tumors. The occurrence of carcinosarcoma in association with a mature cystic teratoma and synchronous tubal carcinoma is very rare. Case Report. A 69-year-old woman presented with a pelvic mass. An abdominal computerized tomographic scan detected a 15 cm right pelvic mass which was suggestive of malignant transformation of a dermoid cyst. Intraoperative, bilateral ovarian masses (left 10 cm and right 12 cm) with diffuse peritoneal metastatic nodules were identified...

INTRODUCTION: Ovarian neuroendocrine tumors are extremely rare. In the ovary, the term of neuroendocrine tumor is usually related to carcinoid tumors although it may be sometimes applied to neuroendocrine carcinomas of non-small cells or small cells cancers usually occurring in the lungs. These carcinoid tumors may develop de novo or from other tumors including teratomas. CASE REPORT: We report a patient who presented with an ovarian carcinoid tumor developed, near or from a dermoid cyst, which was original by its mode of discovery in the dermatology department...

The term collision tumor refers to the coexistence of two adjacent but histological distinct tumors with no histological admixture at the interface. Collision tumors involving ovaries are extremely rare. A collision tumor composed of a dermoid cyst and fibrothecoma is extremely rare in menopausal women. The mechanism of the development of collision tumor is uncertain. During clinical evaluation, differentiation of characters of these ovarian tumors is important to decide appropriate treatment strategies and for good prognosis...

Our knowledge of testicular germ cell neoplasms has progressed in the last few decades due to the description of germ cell neoplasia in situ (GCNIS) and a variety of specific forms of intratubular germ cell neoplasia, the discovery of isochromosome 12p and its importance in the development of invasiveness in germ cell tumors (GCTs), the identification of specific transcription factors for GCTs, and the recognition that a teratomatous component in mixed GCT represents terminal differentiation. Isochromosome 12p and 12p overrepresentation, collectively referred to as 12p amplification, are fundamental abnormalities that account for many types of malignant GCTs of the testis...

Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses...

Mature germ cell derived cystic teratoma of the ovary, i.e. dermoid cyst, is a common ovarian neoplasm, seldom progressing to malignancy. Malignized dermoid cyst is most commonly diagnosed in a woman of approx. 50 years of age, either during or after an operation. Owing to the rarity of the disease, the lines of treatment are based on retrospective series of cases.

Mature cystic teratomas constitute 10-20% of all ovarian neoplasms. Malignant transformation is very rare occurring in only 0.1-2% of mature teratoma cases. Malignant melanoma is among the least common transformations. Herein, we describe a case of young woman initially undergoing evaluation for infertility who was found to have malignant melanoma arising in a mature dermoid cyst. She subsequently underwent unilateral salpingo-oophorectomy with staging procedure with benign pathology. There was no need for adjuvant therapy and the patient is without disease to date (nearly 10-months in follow-up now)...

Although ovarian mature cystic teratomas are the commonest adnexal masses occurring in premenopausal women, there are many challenges faced by gynecologists on deciding upon the best surgical management. There is uncertainty, lack of consensus, and variation in surgical practices. This paper critically analyzes various surgical approaches and techniques used to treat these cysts in an attempt to outline a unified guidance. MEDLINE and EMBASE databases were searched in January 2015 with no date limit using the key words "ovarian teratoma" and "ovarian dermoid...

OBJECTIVE: To demonstrate that the use of 3D/4D HDLive increases the image quality in the diagnosis of benign cystic ovarian teratomas. MATERIALS AND METHODS: 3D/HDLive ultrasound (US) was used in 31 cases of suspected ovarian cystic teratoma using vaginal 2D US. The following pathognomonic images of mature cystic teratomas were considered for diagnosis: 1) a cystic, unilocular lesion with a densely echogenic tubercle (Rokitansky nodule); 2) a diffuse or partially echogenic mass usually demonstrating sound attenuation; 3) fluid-fluid/fat-fluid levels; 4) dermoid mesh with hyperechogenic calcifications indicating the presence of bone, teeth, or other ectodermally-derived structure; 5) multiple mobile spherical structures (fat globules)...

Ovarian teratoma has various presentations. We present a 28-year female diagnosed with a tumour after a fainting episode. Medical history was non-contributory except for mild intermittent pelvic pain. Cardiologic and neurological evaluation found no cause of syncope. Abdominal ultrasound revealed a right ovarian tumour that was laparoscopically removed. The menses continued to be normal. The pathological exam showed an encapsulated tumour of 8 cm with hair and small bone parts (mature teratoma with a cystadenoma)...

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...

BACKGROUND: Ovarian mature cystic teratoma (MCT) is a common neoplasm in women. While malignant transformation of MCT is relatively rare, squamous cell carcinoma is the most frequent malignant neoplasm arising from MCT. Some tumor markers have been reported to be useful for prediction of MCT malignant transformation prior to operation. However, widely accepted use of these markers remains to be established. In the present study, we report the usefulness of frozen section assessment during operation, as well as preoperative measurement of tumor marker levels...

OBJECTIVE: To compare transvaginal versus conventional laparoscopy for dermoid cysts. STUDY DESIGN: We retrospectively analyzed all con-secutive patients with dermoid cysts who underwent transvaginal (n = 219) or conventional (n = 245) laparoscopy from 2007-2013 at our institution. Each group of patients was matched (1:1 ratio) for age, body mass index, previous surgical history, cyst diameter, bilaterality, and cystectomy/oophorectomy. Surgical outcomes were compared between the 2 groups...
