OBJECTIVE To assess the diagnostic value of aspiration cytology in individual cystic lesions of the ovary. STUDY DESIGN During a 42-month period, 235 cystic ovarian lesions were investigated by fine needle aspiration with cytologic examination (FNA). RESULTS Almost 56% (131/235) of the aspirates were devoid of diagnostic cells. The 104 diagnostic aspirates comprised 49 follicular cysts, 4 e...

Malignant transformation of a benign cystic teratoma of the ovary is only rarely seen. A review of the English literature revealed no reports of a malignant melanoma developing from concurrent primary endometrial carcinoma and ovarian cystic teratoma. We report herein a 54-year-old nulliparous woman who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy for a pelvic mass...

The most prevalent type of ovarian germ cell tumour is dermoid cysts, also known as mature cystic teratoma. Dermoid cysts are benign tumours that account for 10–25% all and bilateral in 10%–15% cases. They common reproductive-age women, although they can be detected postmenopausal usually asymptomatic. Torsion, rupture, chemical peritonitis, malignant transformation aggravate it, but infect...

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 ac...

MRL/MpJ (MRL) mice, commonly used as a model for autoimmune disease, have a high frequency of ovarian cysts originating from the rete ovarii. In the present study, to clarify how the rete ovarii, which are remnants of mesonephric tubules during embryogenesis, progress to cystic formation with aging, the morphology of MRL rete ovarii was analyzed and compared with that of normal C57BL/6N (B6) mi...

Germ cell tumors comprise about 20% of all ovarian tumors and most of which are mature cystic teratomas. Monodermal teratomas are germ cell tumors derived from a single germ layer. A 33-year-old-woman revealed to the gynecology outpatient clinic with pelvic pain which is persisting for one month. The physical examination and ultrasounographic evaluation revealed a pelvic mass. Thus, laparotomy ...

Cystic ovarian disease (COD) is an important cause of abnormal estrous behavior and infertility in dairy cows. COD is mainly observed in high-yielding dairy cows during the first months post-partum, a period of high stress. We have previously reported that, in lower mammals, stress induces a cystic condition similar to the polycystic ovary syndrome in humans and that stress is a definitive comp...

Ovarian tumor composed only of Brenner tumor and struma ovarii is very rare; only 6 cases have been reported in the English literature, to the best of the author's knowledge. A 66-year-old woman underwent right oophorectomy because of torsion of right ovarian cyst. Macroscopically, the ovarian cyst was hemorrhagic and red. Cystic content was hemorrhagic fluid. Microscopically, the cyst walls we...

Mural nodules of ovarian mucinous borderline tumors are rare. In this study, we report a case of mural nodules of clear cell carcinoma in an intestinal type mucinous borderline tumor of the ovary. The patient was a 54-years-old woman presented with back and pelvic pain for 3 months. A right-sided multiloculated ovarian mass approximately 20 cm was identified on the CT scan. CA-125 was moderatel...
