Overview

Objective:
Presentation of a rare finding non-Hodgkin´s B-lymphoma of the ovary in a patient during caesarean section.

Design:
Case report.

Settings:
Department of Obstetrics and Gynaecology, Regional Hospital Liberec, a.s.; First Internal Clinic –⁠ Clinic of Hematology, First Faculty of Medicine and General University Hospital, Charles University in Prague; Department of Pathology and Molecular Medicine, Second Faculty of Medicine, Charles University in Praque and Motol University Hospital.

Results:
Pregnant woman, 31-years old, primiparous, with a history of caesarean section was examinated in our department due to nonspecific abdominal pain during her pregnancy. During the caesarean section of fetal indication we found bilateral ovarian tumours. We performed unilateral adnexectomy. Preliminary diagnosis from frozen section was thecoma, but final diagnosis (after definitive histology, imunohistochemistry and molecular investigation) was high-grade B-cell non-Hodgkin´s lymphoma with c-myc and bcl-6 gene rearrangement (double-hit lymphoma) resulting in an unfavourable prognosis. The patient consequently completed 6 cycles of chemotherapy with a biological treatment, and achieved a complete remission. However, after 6 months, an early generalisation to the CNS appeared, leading to intracranial hypertension refractory to anithypertensive and anti-oedematous therapy, consequently leading to death.

Conclusion:
Non-Hodgkin´s lymphoma of the ovary in pregnancy is a rare adnexal tumour whose treatment requires interdisciplinary cooperation.

Keywords:
non-Hodgkin‘s lymphoma, double-hit lymphoma, caesarean section, lymphoma in pregnancy, ovarian tumours
