Ovarian dysgerminoma in two sisters

ABSTRACT

Although rare, dysgerminomas are important irrespective of incidence because they affect women of reproductive age [i.e., <45 years]. Dysgerminomas make up two thirds of all malignant ovarian neoplasms in women younger than 20 years. All dysgerminomas are considered malignant, but only one third of dysgerminomas behave aggressively. Their exact etiology has not been determined. Few reports are found in the review of the literature on the incidence of dysgerminoma and other germ cell tumors in families. Some of these reports focus on the genetic abnormalities associated with germ cell tumor and the responsible gene. Two cases of dysgerminomas diagnosed in two sisters aged 14 and 19 years old are presented here with their radiological studies
