We analyzed 66 cases of immune-mediated thrombophilia in patients with lymphoma reported in the literature. Sixty-one cases had a lupus anticoagulant, three an antibody to protein S, one to protein C, and one to ADAMTS 13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13). Lupus anticoagulants occurred in all histological subtypes of non-Hodgkin lymphoma, except mantle cell lymphoma, MALT (mucosa-associated lymphoid tissue) lymphoma, and angioimmunoblastic T-cell lymphoma, and rarely in Hodgkin lymphoma. The largest number of cases was described in splenic marginal zone and lymphoplasmacytic lymphoma. Lupus anticoagulants were highly associated with immunoglobulin M (IgM) paraproteinemia, autoimmune hemolytic anemia, and immune thrombocytopenia. About half of the patients had thrombotic events (antiphospholipid antibody syndrome). Venous thromboembolism was more than twice as common as arterial thrombosis; 6.5% had a catastrophic antiphospholipid antibody syndrome. The lupus anticoagulant could be eliminated by lymphoma treatment (chemoimmunotherapy or splenectomy) in more than one-third of patients. It is suggested that a search for lupus anticoagulant should be done in all patients with lymphoma, because a diagnosis of lupus anticoagulant may influence the management of lymphomas in some patients.

A 49-year-old woman with severe thrombocytopenia was admitted after an episode of syncope. She also had anemia, fever, pleural effusion and ascites, and multiple lymphadenopathies subsequently appeared. Her bone marrow showed increased megakaryocytes with mild fibrosis, whereas her lymph nodes lacked histologically specific findings. Her presentation was not consistent with multicentric Castleman's disease, angioimmunoblastic T-cell lymphoma, systemic lupus erhythematosus or any other well-recognized entities. Her clinical features were, however, thought to be compatible with TAFRO (thrombocytopenia, anasarca, fever, reticulin fibrosis, and organomegaly) syndrome. Corticosteroid therapy induced a partial remission of fever and systemic fluid retention, but thrombocytopenia persisted. After additional immunosuppressive therapy with cyclosporin A, her symptoms showed full resolution. [J Clin Exp Hematop 53(1) : 95-99, 2013].

Several conditions have clinical and laboratory features that can mimic those present in Systemic Lupus Erythematosus (SLE). Some of these "SLE mimickers" are very common, such as rosacea which can be mistaken for the butterfly rash, while others such as Kikuchi disease, type-1 interferonopathies, Castleman's disease, prolidase deficiency, angioimmunoblastic T-cell lymphoma, Evans' syndrome in the context of primary immune deficiencies and the autoimmune lymphoproliferative syndrome are exceptionally uncommon. A proper diagnosis of SLE must therefore be based upon a complete medical history as well as on the adequate constellation of clinical or laboratory findings. While there is no single test that determines whether a patient has lupus or not, the search for auto-antibodies towards nuclear antigens is a key step in the diagnosis strategy, keeping in mind that ANAs are not specific for SLE. In case of persistent doubt, patients should be referred to reference centers with experience in the management of the disease.
