Objectives Describe malignant ovarian tumors in patients 14 - 20 years, between 1985 - 2015 at San Borja Arriaran Hospital (HCSBA) in Santiago, Chile. HCSBA is a public institution that covers about 20% of the chilean capital population.
Methods Retrospective search in the gynecology oncology and pathology HCSBA units data bases of the following parameters; histology type and age of initial diagnostic. We found a total of 20 records of female patients with malignant germ germ cell tumors between 14–20 years, that were reviewed and analyzed by 3 members of our unit.

The most common epithelial tumor was mutinous borderline (38%) followed by serous adenocarcinoma (38%) and serous borderline (25%) There were only 2 cases of stromal cancer. 85% of the tumors were early FIGO stage; 60% IA and 25% IC.
