Definition / general
  • Can be primary or secondary
  • Arises from hilar lymphoid tissue or ovarian teratoma
Clinical features
  • Fox et al. proposed 3 criteria for the diagnosis of primary ovarian lymphoma (Br J Obstet Gynaecol 1988;95:386):
    1. Confined to ovarian regional lymph nodes or adjunctive organs at diagnosis
    2. NO abnormal cells in bone marrow or peripheral blood, and
    3. Any extraovarian disease must occur at least a few months after the appearance of the ovarian lesions
  • Normal serum CEA, CA125, CA19–9

Prognostic factors
  • Histologic type is most important prognostic factor
  • B cell tumors associated with longer survival (Gynecol Oncol 2003;90:215)
Case reports
  • Based on histology, type, and clinical staging
  • Surgery, chemotherapy (CHOP or Rituxan-CHOP) or radiotherapy
