ABSTRACT

INTRODUCTION: Kidney involvement in non-Hodgkin lymphoma is recognized but mostly diagnosed following a diagnosis of lymphoma. We describe a rare case of mantle cell lymphoma, a B-cell-type non-Hodgkin lymphoma, first presenting with immune complex glomerulonephritis. CASE PRESENTATION: We report the case of a 58-year-old Sri Lankan man who presented with gross hematuria. Further investigation revealed bicytopenia with splenomegaly and elevated serum creatinine. He had a renal biopsy, which revealed acute immune complex glomerulonephritis with interstitial inflammation. Results from an initial bone marrow biopsy and blood imaging were inconclusive. Three months later his renal function had deteriorated and a lymph node biopsy revealed mantle cell lymphoma. Within three months of initiating chemotherapy, his renal function returned to normal levels and remained normal at one year of follow-up. CONCLUSIONS: It is important to have a high degree of suspicion when patients present with acute immune complex glomerulonephritis with no other identifiable cause, because it could be the first presentation of a non-Hodgkin lymphoma such as mantle cell lymphoma.

ABSTRACT

INTRODUCTION: Primary antiphospholipid syndrome can be a difficult diagnosis in the absence of typical clinical features. We describe an unusual presentation of primary antiphospholipid syndrome mimicking vasculitis for which the only diagnostic clue on initial presentation was antiphospholipid syndrome nephropathy. CASE PRESENTATION: A 29-year-old Sri Lankan woman presented with features mimicking vasculitis with no obvious clinical features of antiphospholipid syndrome. Classical symptoms of antiphospholipid syndrome only appeared months later. A retrospective analysis showed that the only evidence of antiphospholipid syndrome at her first presentation was antiphospholipid syndrome nephropathy on her renal biopsy. CONCLUSIONS: A high degree of suspicion of antiphospholipid syndrome is needed when patients present with non-specific vasculitis features. It has a broad clinical impact as antiphospholipid syndrome can present to any clinician with rare manifestations such as nephropathy. This significantly adds to the advancement of knowledge as antiphospholipid syndrome nephropathy should be recognized as a true entity and considered as a classification criteria for antiphospholipid syndrome.
