Objectives Our purpose was to evaluate the risks of malignancy in surgically removed ovarian cysts that preoperatively were characterized as unilocular by transvaginal sonography. Study design This prospective analysis included 1307 women operated at two European university Hospitals between January 1992 and December 1997. Based on ultrasonographic findings the cysts were characterized either as echo‐free, without solid parts or papillary formations (group I) or cysts with solid parts/papillary formations or echogenic cyst content (group II). Ultrasonographic and macroscopic appearance of the cysts were compared with histopathological diagnosis. Results In group I seven of 670 (1.1%) proved to be borderline or malignant, and all measured ≥ 75 mm in diameter. The corresponding figures for cysts in group II were 24 of 634 (3.8%). The frequency of borderline/malignant cysts increased significantly with the size of the cysts. Conclusion Unilocular, echo‐free cysts (group I) with a mean diameter above 50 mm and all unilocular cysts with solid parts/papillary formations should be removed surgically. Serial ultrasound follow‐up should be the standard procedure of unilocular, echo‐free cysts less than 50 mm.
