Justification:

Ovarian lesions in children have not been very studied in Costa Rica, this study will allow a better understanding of the characteristics of them in the country, improving their treatment. Comparing the data obtained with the results of similar studies worldwide, Costa Rica will have better information to treat new cases and be updated internationally.

Methods:

The research is based on observation and description of data found in the files of the girls who were treated at the “Dr. Max Peralta Jiménez” Hospital in Cartago, for ovarian lesions in the period from 2003 to 2013 and subsequent comparison with international studies.

Results:

The most frequent ages of diagnosis include girls from 10-12 years old (61.5%). The most common clinical manifestation was abdominal pain with a 53.8%. Non-neoplastic ovarian lesions showed a 58.8% compared to neoplastic lesions with 41.1%, with 87.8% of these classified as histologically benign and only 14.29% as malignant lesions. Simple cyst was the most prevalent nonneoplastic histopathological finding, covering 70.0%. Laparotomy was the most common surgical method of management with 76.9%, and the most used technique corresponds to the salpingooophorectomy with 41.1% of cases.

Conclusions:

The average age of presentation of ovarian lesions was 9.5 years. The most common initial clinical manifestation corresponded to abdominal pain. Non-neoplastic lesions were the most prevalent and of these, simple cysts were the most common finding. The prefered surgical method was laparotomy and the most widely used technique was the salpingo-oophorectomy.
