Primary bilateral ovarian Burkitt's lymphoma in a six-year-old child: report of a rare malignancy.

Primary ovarian non-Hodgkin lymphoma (NHL) is rare and accounts for 0.5% of all NHLs. Here, we present a case of primary bilateral ovarian NHL in a six-year-old girl. The patient presented with lower abdominal pain and difficulty in walking. Subsequent ultrasonography and computed tomography revealed bilateral ovarian mass. The diagnosis of NHL was established after bilateral adnexectomy and histologic study of excised tissue. After thorough immunohistochemical evaluation, the tumor was diagnosed as Burkitt's lymphoma (Peripheral/Mature B cell neoplasm, Burkitt type according to WHO classification). The patient received 4 cycles of CODOX-M regimen. Six months follow up after surgery is unremarkable.
