title: [Histology and cytology of laparoscopically operated "simple ovarian cysts"].
abstract: In a retrospective study the histopathological findings of 127 laparoscopically operated unilocular anechoic smooth-walled ovarian cysts have been correlated with clinical characteristics (age, duration of observation, complaints, hormonal treatment), size by ultrasound, kind and colour of cysts content as well as cytological findings. The age of patients differed from 16-61 years (mean +/- s: 36 +/- 16). The histopathologic findings yielded 15 (11.8%) functional cysts, 30 (23.6%) persistent corpus luteum cysts, 9 (7.1%) endometriomas, 7 (5.5%) cystic teratomas, 9 (7.1%) undifferenciated cysts and 57 (44.9%) cystadenomas. There were no differences between histopathologic diagnosis groups according to age and cysts size by ultrasound. Functional cysts with complaints (n = 6) may explain that the observation time in 60% of all functional cysts was smaller than 6 weeks, whereas persistent corpus luteum cysts, endometriomas, cystic teratoma and cystadenomas had been observed for longer than 6 weeks in more than two thirds. Intraoperative evaluation of cysts content as "chocolate"-like was suspicious of endometriomas, but was also present in cysts of other histopathological findings. By means of cytology, endometrioma (siderophages) was suspected in 44.4% and a cystadenoma in 42.1% of all histopathologically verified cases. In all, the cytologic findings were useful for correct histopathological diagnosis in only 33.9% of all 127 cases. It is concluded that differential diagnosis of simple ovarian cysts is not possible by clinical characteristics, neither by ultrasound nor by cytological evaluation. Ovarian cysts should be observed for at least two hormonal cycles. A hormonal treatment by combination preparations containing high doses of oestrogen is also recommended. In cases of persisting ovarian cysts laparoscopic removal is necessary.
