title: Diagnosis, pathology, staging, treatment, and outcome of epithelial ovarian neoplasia in patients age < 21 years.
abstract: BACKGROUND
  Epithelial ovarian neoplasms are rare in patients under the age of 21 years. This is a report of a series of such patients documenting their presentation, histologic type, stage of disease, treatment, and outcome.
  
  
  METHODS
  Clinical findings, histology, stage, treatment, and outcomes of 19 patients with epithelial ovarian neoplasia are reported. All histology was rereviewed.
  
  
  RESULTS
  The median age at the time of diagnosis was 19.7 years (range, 14.1-21.8 years), and the median follow-up was 5.6 years (range, 0.2-19.5 years). The most common presenting symptom was dysmenorrhea (100%) followed by abdominal pain (68%), and the initial diagnosis usually was made ultrasonographically. There were nine (47%) serous tumors, 7 (37%) mucinous tumors, 2 (11%) small cell carcinomas, and 1 (5%) endometrioid carcinoma. Seventy-nine percent of tumors were unilateral, and 84% were low malignant potential or well differentiated tumors. Surgical treatment included unilateral salpingo-oophorectomy in 12 patients (63%), total abdominal hysterectomy and bilateral salpingo-oophorectomy in 6 patients (32%), and ovarian cystectomy in 1 patient (5%). Fifteen patients (79%) had Stage I disease, and 4 patients (21%) had Stage III disease at the time of diagnosis. There were two deaths in this series, and both occurred in patients with small cell anaplastic carcinoma.
  
  
  CONCLUSIONS
  Epithelial ovarian neoplasias are rare in patients in this age group but must be included in the differential diagnosis of an ovarian mass. Most patients present with Stage I tumors of low malignant potential. In these patients, good survival is achieved with unilateral salpingo-oophorectomy and preservation of fertility. In contrast, small cell carcinomas are very aggressive, and patients with this variant require intensive therapy.
