INTRODUCTION:

Non-Hodgkin's lymphomas are a heterogeneous group of neoplasms hematolymphoid, with main lymph node manifestation; a small percentage have an extra-nodal origin. Some cases of non-Hodgkin's lymphomas have been described.Primaries of the ovary and, in general, of the female genitourinary duct. Because of his they infrequently pose a diagnostic, clinical and pathological challenge. We report the case of a patient with primary ovarian non-Hodgkin's lymphoma, who underwent primary surgical cytoreduction and adjuvant treatment with systemic chemotherapy. The bibliography around the criteria is reviewed diagnosis and prognosis of the disease.

CLINICAL CASE:

A 65-years-old patient who presented constitutional syndrome and urinary irritative symptoms, her vital signs at the admission were normal, at the physical examination bilateral grade 2 edema in lower limbs and mucocutaneous paleness was observed, heterogeneous hypochromic microcytic anemia, thrombocytosis and also a right complex ovarian mass were documented during the hospitalization, for this reason was treated with primary surgical reduction, the histopathological result was Ovarian Primary Non Hodgkin B-cell Lymphoma, for that reason systemic adjuvant chemotherapy with R-CHOP scheme was initiated, at the ten month follow-up radiological and nuclear examinations were performed confirming the remission of the disease.

CONCLUSIONS:

Primary ovarian non-Hodgkin lymphoma is an unusual extra-nodular hematolymphoid neoplasm that requires a histopathological confirmation. The prognosis according to the literature review for the disease limited to the ovary has an overall survival rate of 79% to 10 years after diagnosis. More studies are required to characterize the prognosis and diagnostic approach of this entity.
