Dermoid cysts of the ovary.

From 1965 to 1984, 105 cases of ovarian dermoid cysts have been diagnosed and treated at the First Clinic of Obstetrics and Gynecology, Catania University, Catania, Italy. The patients were aged between 9 and 70 years, with a higher frequency of dermoid cysts between 26 and 30 years (21.91%, 23 cases). In 0.95% (1 case) the patient was premenarchal, 84.76% (89 cases) in fertile age, and in 14.29 (15 cases) in menopause. 35.22% (37 cases) were nulliparous with an average of 31 years, and 64.76% (68 cases) pluriparous with an average age of 38.9 years. In 4.76% (5 cases) the patients had already been treated for dermoid cysts. The asymptomatic form occurred in 13.33% (14 cases), while in 9.52% (10 cases) of cases there was torsion of the cyst. In 89.53% (95 cases) the cyst was monolateral, double in the same ovary in 0.95% (1 cases), and bilateral in 9.52% (10 cases). Epithelial cancerous degeneration occurred in 1.95% of cases (2 cases). In 11.43% (12 cases) enucleation of the cyst was performed while in the other cases therapy was chosen in relation to age, parity, and associated gynecological pathology of the patients. The Authors compare their data with that in literature.
