Abstract
Primary ovarian lymphoma is extremely rare. We report a case of primary T-cell lymphoblastic lymphoma of the ovary in a 31-year-old multiparous woman, who presented with abdominal pain. Her menstrual cycles were regular. There was no generalized lymphadenopathy or fever. On per abdominal examination, there was a firm, tender, solid, mobile mass with well-defined borders, corresponding to 20 weeks gestation, whose lower pole was easily reached. Per vaginum examination revealed a large adnexal mass in the right and anterior fornix. Transabdominal ultrasonography showed bilateral solid ovarian tumor measuring 13.9 cm × 11.8 cm on the right side and 10.0 cm × 6.3 cm on the left side with significant vascularity. Tumor markers were within normal limit except for significantly elevated serum lactate dehydrogenase. Magnetic resonance imaging showed two large solid homogeneous masses, hypointense on T1W1 and hyperintense on T2W1 imaging, with a normal sized uterus and no ascites or lymphadenopathy. The patient developed one episode of left hemiparesis preoperatively, which improved spontaneously. Staging laparotomy with total abdominal hysterectomy and bilateral salpingo-oophorectomy along with infracolic omentectomy was done. Histopathology with immunohistochemistry revealed primary T-cell lymphoblastic lymphoma of the ovary, involving both ovaries left fallopian tube and left serosal surface of fundal region of uterus. She developed generalized convulsions on the 12th postoperative day, and final diagnosis was primary ovarian T-cell lymphoblastic lymphoma Ann Arbor Stage IV. She received three cycles of chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisolone regimen and was on palliative care. She succumbed to her illness 5½ months postoperatively.

Introduction
Primary ovarian lymphoma is rare. We report a case of primary T-cell lymphoblastic lymphoma of the ovary, and discuss the challenges in the diagnosis and management of the case.
Case Report
The 31-year-old multiparous woman presented with abdominal pain of 2-month duration. Her menstrual cycles were regular, last menstrual period being 19 days back. She had two normal deliveries before, and her last childbirth was 9 years back. She was not on any contraceptives. There was no significant past or family history, including no history of familial cancers or fever. On examination, she was of average built, with no pallor or generalized lymphadenopathy. Her vitals were stable. On per abdominal examination, there was a firm, tender, solid, mobile mass of 20 weeks gestation; whose lower pole was easily reached. Per vaginum examination revealed large adnexal mass palpated in the right and anterior fornix, left fornix being free.
The patient was further worked up at our institute. Her hemoglobin was 10.9 g%, and peripheral smear, kidney function tests, and liver function tests were within normal limits. Transabdominal ultrasonography revealed bilateral solid ovarian masses [Figure 1a], measuring 13.9 cm × 11.8 cm on right side and 10.0 cm × 6.3 cm on left side, with significant vascularity on color Doppler [Figure 1b]. Her serum lactate dehydrogenase was significantly elevated, measuring 838 U/L, while CA-125 was 42.1U/ml. Other tumor markers – CA-19-9, carcinoembryonic antigen, alpha-fetoprotein, and human chorionic gonadotropin were within normal limits. Upper gastrointestinal endoscopy was normal, and stool for occult blood was negative. Computed tomography (CT) revealed two large solid masses arising from bilateral ovaries, with no ascites or lymphadenopathy [Figure 1c]. Magnetic resonance imaging (MRI) abdomen and pelvis were done for further delineation, which showed two large solid homogeneous masses, right > left, hypointense on T1W1 [Figure 1d] and hyperintense on T2W1 imaging [Figure 1e], with a normal sized uterus and no ascites. With a preoperative diagnosis of bilateral solid ovarian tumor in a young parous woman, the patient was planned for laparotomy.

However, 1 day before surgery, she developed acute onset left hemiparesis, which improved spontaneously over the next 24 h. CT brain showed multiple ill-defined hypodensities in the right parasagittal, right middle cerebral artery and posterior fossa [Figure 1f], suggestive of? infarcts/?demyelination. It was advised to go ahead with laparotomy.

On immunohistochemistry, tumor cells were strongly and diffusely positive for T-cell markers-Tdt, CD-99, BCL2, and CD-10 [Figure 2f], and negative for B-cell markers – CD-20 and CD-79 [Figure 2g], with a very high proliferative index (MIB1 – 95%–100%). Bone marrow was negative for infiltration by lymphoblastic cells. Pathological diagnosis was T-cell lymphoblastic lymphoma involving both the ovaries, left fallopian tube and left serosal surface of fundal region of uterus. On day 12, she developed generalized convulsions while awaiting chemotherapy. MRI brain showed an increase in size of the space occupying lesion in the right subcortical parasagittal area measuring 2.5 cm × 3.0 cm [Figure 1g], with diffuse brain edema. Her final diagnosis was primary ovarian T-cell lymphoblastic lymphoma Ann Arbor Stage IV. She received three cycles of chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisolone regimen, and was on palliative care. She succumbed to her illness 5½ months postoperatively.
Discussion
Primary ovarian lymphoma is rare, with an incidence of 1.5% of all ovarian neoplasms, and 0.5% of all non-Hodgkin's lymphoma (NHL).[1,2] It probably arises from lymphocytes of both B- and T-cell lineage occurring within cortical granulomas, in ovarian stroma, and within ovarian follicles and corpora lutea.[3] Burkitt's lymphoma and diffuse large B-cell lymphoma are the most common histologic types seen in NHL of ovary.
Primary ovarian lymphoma is diagnosed by Fox's criteria.[4] In this case, probably due to late presentation, the extra-ovarian (brain) lesions presented within days of admission of the patient. The mean age at presentation is 47 years, with common presentation being pelvic complaints, and the size of the neoplasms ranging from 7.5 cm and 20.0 cm, mean being 13.3 cm.[5]
The preoperative imaging findings have been retrospectively described.[6,7] Ovarian lymphomas are frequently bilateral, homogeneous, without ascites, and exceeding 5 cm in diameter. Ultrasound is nonspecific with hypoechoic pattern of the ovarian mass. On CT, ovarian lymphomas appear as hypodense lesions with mild contrast enhancement. On MRI, ovarian lymphoma must be considered when large bilateral ovarian masses with a lobulated and homogeneous appearance are seen in the absence of ascites, with low signal intensity on T1W1 and mild hyperintensity on T2W1.
Image-guided core biopsy of pelvic masses has been described to be safe and accurate.[8,9,10] Primary ovarian lymphomas are staged as other extranodal NHLs using the Ann Arbor staging system. Treatment of primary ovarian lymphomas is based on histology, type, and clinical staging. Most patients have been treated by various combinations of surgery, chemotherapy, and radiotherapy.[5] However, chemotherapy is the treatment of choice, and hence, preoperative accurate diagnosis by imaging and guided biopsy helps.
Conclusion
Primary ovarian lymphomas, though rare, should be kept in mind in the differential diagnosis of solid ovarian tumors for optimal patient outcome.
