Benign ovarian masses.

Primary tumors of the ovary are uncommon in children and the majority of these masses are not malignant. As newer diagnostic imaging techniques have increased the detection of all ovarian masses, the frequency of ovarian cancer has actually decreased. Clinical symptoms are generally not helpful in distinguishing benign from malignant masses, but radiographic criteria have been developed. Surgical treatment is aimed at ovarian preservation if the lesion proves benign.
