Definition / general
- Can be primary or secondary
- Arises from hilar lymphoid tissue or ovarian teratoma
Clinical features
- Pelvic pain, pelvic mass, and urinary frequency and incontinence
- Ages 6 to 74 years
- Usually B cell type
- Children: usually Burkitt lymphoma
- Adults: usually diffuse large B cell or follicular lymphoma (Adv Anat Pathol 2001;8:200)
- May be difficult to determine if primary or secondary
- Primary ovarian tumors have better prognosis (Gynecol Oncol 2004;95:750)
- 5 year survival is 80% after surgery or chemotherapy in primary disease vs. 33% in secondary disease (Mod Pathol 2001;14:1093, Am J Surg Pathol 1993;17:154, Arch Pathol Lab Med 1994;118:647)
Diagnosis
- Fox et al. proposed 3 criteria for the diagnosis of primary ovarian lymphoma (Br J Obstet Gynaecol 1988;95:386):
- Confined to ovarian regional lymph nodes or adjunctive organs at diagnosis
- No abnormal cells in bone marrow or peripheral blood, and
- Any extraovarian disease must occur at least a few months after the appearance of the ovarian lesions
Laboratory
- Normal serum CEA, CA125, CA19–9
Radiology description
- USG shows homogeneous, hypoechoic, solid cystic mass (Radiol Med 1998;95:493)

Prognostic factors
- Histologic type is most important prognostic factor
- B cell tumors associated with longer survival (Gynecol Oncol 2003;90:215)
Case reports
- 23 year old woman with diffuse large B cell lymphoma, spindle cell variant (Arch Pathol Lab Med 2003;127:e169)
- 38 year old woman with primary ovarian diffuse large B cell lymphoma (Case Rep Obstet Gynecol 2013;2013:493836)
- 50 year old woman with diffuse large B cell lymphoma (Case #295)
Treatment
- Based on histology, type, and clinical staging
- Surgery, chemotherapy (CHOP or Rituxan-CHOP) or radiotherapy
Gross description
- Mostly unilateral
- Microscopic to 15 cm
- Solid whitish fleshy mass

Primary ovarian lymphoma
Microscopic (histologic) description
- Burkitt lymphoma tends to grow in cords or nests forming pseudoacini, accompanied by sclerosis and resembling carcinoma
- Diffuse large cell lymphoma may appear as short fascicles and form interlacing bundles of spindle cells, resembling a stromal tumor; has diffuse pattern of tumor cells with large vesicular nuclei and prominent nucleoli
