| Summary: | Introduction: The involvement of the Female Genital Tract
(FGT) by lymphoma is extremely rare, with ovaries being most
commonly affected. Less than 1% of lymphomas present with
ovarian involvement and less than 1.5% of ovarian neoplasms are
of lymphoid origin. Secondary involvement of ovary by systemic
lymphoma is more common than Primary Ovarian Lymphomas
(POL) which is usually Primary Ovarian Non-Hodgkin lymphoma
(PONHL) of B-cell lineage.
Aim: To understand the clinicopathological and immunomorphological features of Primary Ovarian Non-Hodgkin
lymphoma.
Materials and Methods: This was a descriptive retrospective
study conducted at Department of Pathology, Kidwai Memorial
Institute of Oncology, Bengaluru, Karnataka. India, for a
duration of 14 years between July 2006 to June 2020. Eight
cases of PONHL were identified from departmental archives and
clinicopathological and Immunohistochemistry (IHC) findings of
these tumours were analysed.
Results: The PONHL constituted 0.4% of all Non-Hodgkin
lymphoma (NHL) reported during the study period. The
patients age ranged from 13-60 years with a mean age of
34 years. Among eight cases of PONHL, two cases were of
Diffuse Large B-Cell Lymphoma (DLBCL), followed by one
case each of High-Grade B-Cell Lymphoma, Not Otherwise
Specified (HGBL, NOS), Follicular Lymphoma (FL), Burkitt
Lymphoma (BL), Plasmablastic Lymphoma (PBL), Precursor
B-Lymphoblastic Lymphoma (B-LBL), and precursor
T-Lymphoblastic Lymphoma (T-LBL). Seven cases were staged
IE (Ann Arbor staging system) while one case was designated
as stage IIE.
Conclusion: This was probably the first study on PONHL
from India. The diagnosis of PONHL is challenging unless
there is a high index of suspicion as these patients present
with non specific pelvic symptoms and can be misdiagnosed
as other epithelial, stromal or germ cell ovarian neoplasm
which differs in treatment and prognosis. Histological
examination with IHC and molecular testing are essential to
establish a diagnosis. |
