ABSTRACT
Ovarian tumors are relatively rare in children and adolescent. The incidence of malignancies in these groups is 1% to 1.5%. The common histologic type is non-epithelial type such as germ cell tumors or sex cord-stromal tumors and only 10% to 17% of those are epithelial tumors. It is important to accurately diagnose in the early these rare tumors for proper staging and treatment to save the patient's life and fertility. We present a case of a 13-year-old girl with a giant ovarian mucinous borderline tumor.

Epithelial borderline ovarian tumors (BOT) are distinctive from benign tumors and carcinoma. They occur in younger women more often than carcinoma, and there is some difficulty making correct diagnosis of BOT. Two subtypes of BOT, serous and mucinous borderline tumor have different characteristics and very different clinical behavior. Serous borderline tumor (SBT) with micropapillary pattern shows more incidence of extra ovarian disease and often coexists with invasive implant. SBT with micropapillary pattern in advanced stage has showed a worse prognosis than typical SBT. Huge mucinous borderline tumors have histologic heterogeneity, and the accuracy of frozen section diagnosis is relatively low. Extensive sampling is required to reach a correct pathological diagnosis. Mucinous adenoma (intestinal type) also runs the risk of recurrence after cystectomy, or intraoperative rupture of cyst. Laparoscopic procedure for BOT has not increased the risk of recurrence. Fertility preserving procedures are generally accepted, except in advanced stage SBT with invasive implants. Only cystectomy shows a significant risk of recurrence. Re-staging surgery and full staging surgery is not necessary for all BOT. We should not attempt to treat them uniformly, by the single diagnosis of "borderline tumor". It depends on histologic type. Close communication with the pathologist is necessary to gain more detail and ask more pathological samples in order to make the optimal treatment strategy for each individual patients.

We report MR imaging findings of a rare case of endocervical mucinous borderline tumor (MBT) involving the cul-de-sac and left fallopian tube arising from extensive pelvic endometriosis with pathologic correlation in a 35-year-old woman presented with vague pelvic pain. Endocervical MBT is a type of endometriosis-associated carcinoma. Imaging findings of endocervical MBT are unilocular or oligolocular cystic lesions with enhancing mural nodules, which are different from those of the more common intestinal type MBT.

The ovarian mucinous tumor associated with true sarcoma is very rare. Four cases of true sarcoma: fibrosarcoma, undifferentiated sarcoma, rhabdomyosarcoma, angiosarcoma in ovarian mucinous tumor have been reported. We present a case of mucinous borderline tumor associated with undifferentiated sarcoma with angiosarcoma-like appearance in 80-year-old woman.
