Primary Ovarian Non-Hodgkin's Lymphoma: An 18-year Retrospective Institutional Study and Review of Literature from India, 2023

Methods: We retrospectively reviewed the institutional medical oncology database for newly diagnosed NHL cases between 1999 and 2017. We aimed to study the clinical characteristics, pathology, and outcome of primary ovarian non-Hodgkin's lymphoma (NHL) cases presented to our institution. Results: We identified three patients (3.7% of extranodal NHLs and 0.85% of all NHL patients) with primary ovarian NHL from 350 NHL patient records. They underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by six to eight cycles of (rituximab, adriamycin, cyclophosphamide, vincristine, prednisolone (R-CHOP/CHOP), and they attained complete remission. Conclusion: Given the heterogeneity of cancer incidence in India and the absence of state-wise cancer registries, our study argues a pressing need to develop a national representative registry for NHL for accurate incidence, mortality, and survival data. Additionally, fertility preservation is an important issue that must be discussed with women of fertile age and the parents of children.
Superwarfarin Exposure: An Important Uncommon Cause of Painless Bleeding, 2019

Although a significant number of superwarfarin exposure cases are diagnosed every year, we believe there appears to be delay in diagnosis and confusion in determining what is the ideal way to treat and monitor these patients during the management. This is the first thorough literature review of all the reported cases of superwarfarin poisoning which also studied the clinical presentation, management and follow-up patterns. We present a 70-year-old man who presented to the emergency room with epistaxis, melena, cola-colored urine with elevated prothrombin time (PT), activated partial thromboplastin time (aPTT) and international normalized ratio (INR). Mixing studies showed complete correction of coagulopathy indicative of factor deficiency. Additional history revealed that the patient had arguments with family member at home and made us suspect superwarfarin exposure. Qualitative brodifacoum testing was positive and was managed with fresh frozen plasma and high doses of vitamin K1 (phytomenadione) with serial monitoring of INR and clinical symptoms. Superwarfarin poisoning should be considered in the differential diagnosis of a patient who presents with above clinical and laboratory profile especially in the absence of any history of coagulopathy or anticoagulant use. We want to raise public and especially physician awareness that history taking, early diagnosis and managing in right clinical setting play a significant role in survival of these patients.
