Lymphoblastic Lymphoma Presenting as Bilateral Ovarian Mass in an Adolescent Girl.

BACKGROUND: Lymphomas rarely involve the genital tract and non-Hodgkin lymphoma (NHL) presenting as ovarian tumor is rare. Precursor B-cell lymphoblastic lymphoma arising from the ovary is extremely rare and to our knowledge, only 5 cases have been reported in the literature.

CASE: A 15-year-old girl presented with bilateral ovarian masses, which, on biopsy proved to be precursor B-cell lymphoblastic lymphoma. She was treated with a Berlin-Frankfurt-Munster 90 protocol and she is alive in complete remission for more than 10 years.

SUMMARY AND CONCLUSION: NHL of the ovary should also be considered as a differential diagnosis in adolescent and young adults with ovarian masses. Attempt to make a preoperative diagnosis is crucial because ovarian NHL responds well to chemotherapy and has a good prognosis.
