Unusual presentations of Non Hodgkin lymphoma Part I: A rare case of Primary malignant lymphoma of spleen presenting as splenic abscess

Non Hodgkin lymphoma (NHL) is well known for its unusual clinical presentations, varying sites of origin and spread in an unpredictable fashion. Each case of extra nodal lymphoma will have some unique feature. We worked up a series of very unusual cases of NHL, with rare clinical presentations, histopathological features, management modalities and prognosis.Here we are reporting a case which presented as a retroperitoneal abscess and massive splenomegaly, along with auto-immune haemolytic anemia.Splenectomy was done and the final histopathological diagnosis was Non-Hodgkin's lymphoma, large cell type, with dominant splenic involvement.The condition is also termed primary malignant lymphoma of spleen (PMLS).The patient's haemotological status improved immediately after splenectomy.
