ABSTRACT A retrospective review of an entire clinical series of 152 women over 50 years of age, in whom cystic lesions without solid parts had been diagnosed by ultrasound, found there were no malignancies in 58 completely anechoic lesions less than 5 cm in diameter. Of 10 small lesions (less than 5 cm in diameter) with some echogenicity or septa, one was a borderline tumour. In contrast, in patients with lesions greater than 5 cm in diameter there were three malignancies in the group of 33 totally anechoic cysts, five in the group of 32 cysts with some echogenicity, and as many as eight malignancies in the 18 lesions where several septa were present. Two borderline and one malignant tumour had been missed at previous clinical examination. We conclude that small anechoic lesions are seldom, if ever, malignant in elderly women. Sonography is helpful in patients with a negative clinical examination when pelvic pain or signs of malignancy are present.

    ABSTRACT: Ovarian neoplasms are common in women of all ages. As many as 10% of women in the United States will undergo surgical removal of an adnexal mass sometime in their lifetime. Gynecologic surgeons have pioneered laparoscopic surgery, developing what was originally a diagnostic tool into a safe and effective approach to management of adnexal masses. Accumulating scientific data support the laparoscopic approach to the adnexal mass as the preferred treatment.

    ABSTRACT: To assess the potential of expectant management for simple ovarian cysts diagnosed by transabdominal or transvaginal ultrasonography. To compare the results of needle aspiration with those achieved with simple observation. Randomised trial. Hospital department of obstetrics and gynaecology. 278 women with simple cysts randomly allocated to simple observation (143) or ultrasound guided fine needle aspiration (135) between 1990 and 1994. Resolution of cyst or development of malignancy. After six months 269 were available for follow up. The rate of resolution was 46% (59/128) with aspiration and 44.6% (63/141) with observation. Only the diameter of the cyst (P < 0.0001) was a significant independent prognostic factor for resolution in a multivariate analysis. Age and treatment had no significant effect. One woman was subsequently found to have borderline malignant changes on histopathological examination. Her cyst was detected by transabdominal ultrasonography. Expectant management for up to six months does not cause risks for the patients and allows spontaneous resolution in over a third of cases, avoiding the costs and risks of unnecessary surgery. Aspiration does not provide better results than simple observation.

    ABSTRACT: To assess the diagnostic efficacy of Fine Needle Aspiration Cytology in differentiating neoplastic and non-neoplastic dysfunctional ovarian cysts--cytological findings to be verified with histology of excised cyst. In this prospective study fifty-three cases with unilocular nonseptate ovarian cystic masses,detected on ultrasound examination were subjected to ultrasound guided fine needle aspiration of the cyst contents at Department of Pathology, Allama Iqbal Medical College Lahore, from January 1999 - January 2000. Aspirated fluid was examined cytologicaly using Giemsa stain on the smears prepared from centrifuged deposit. The same cyst removed surgically was examined histologicaly and cytohistological correlation was carried out. In this series of 53 cases, histologically confirmed break up of various types of cysts was follicular cysts (n=25), leuteal cysts (n=6), serous cysts (n=15), mucous cysts (N=4) and Endometriotic cysts (n=3). Non-diagnostic fine needle aspirate was obtained in 19/53 cases, majority being the follicular cysts. The cytohistological correlation revealed no false positive but 40% false negative results for follicular cysts on cytological examination of the aspirate. Hence the specificity and sensitivity for cytological diagnosis of follicular cyst was 100% and 60% respectively. For leuteal cysts, false positive and false negative results on cytological examination were 0% and 16.6% respectively with a specificity and sensitivity value of 100% and 83% respectively. For neoplastic serous cysts cytologically false positive and false negative diagnosis was 0% and 46.6% respectively with specificity and sensitivity of 100% and 53%. For mucinous cystadenomas sensitivity and specificity of cytological diagnosis was 100%. For endometriotic cysts a sensitivity of 67% and specificity of 100% was procured with cytological evaluation. Guided fine needle aspiration cytology may prove to be one of the most valuable and acceptable tools in the differential diagnosis of ovarian cystic lesions.
