Abstract
Hemophagocytic lymphohistiocytosis (HLH) association with an underlying lymphoma is an uncommon entity in paediatrics. It may precede lymphoma diagnosis by several years or may occur at the time of remission or relapse of lymphoma. Simultaneous occurrence of HLH & lymphoma is rare. We here with report a case where HLH was the initial presentation which masked the diagnosis of lymphoma, however tissue biopsy revealed the underlying non-Hodgkin's lymphoma.
