In this report the association of autoimmunity and autoimmune syndromes with lymphoproliferative disorders (LPD) is described in 15 patients. Non-Hodgkin's lymphoma (NHL) developed in 10 patients, Hodgkin's disease (HD) in 3 and chronic lymphocytic leukemia (CLL) in two. In most instances clinical and laboratory phenomena preceded the development/diagnosis of these disorders. Manifestations ranged from the presence of autoantibodies in the serum to the presence of both ill defined or incomplete autoimmune syndromes including cold urticaria, Raynaud's phenomenon, cold agglutinin disease, thyroiditis, nephrotic syndrome and vasculitis to typical systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and even one of scleroderma. It is suggested that in some patients (in)complete clinical manifestations of autoimmunity may precede the development of lymphoid neoplasias. The link between autoimmunity and lymphoproliferative disorders is briefly discussed.

Urticaria has been observed occasionally in association with lymphoproliferative disorders. We report the case of a 56-year-old man with acute urticaria associated with a small cell carcinoma of the lung. Following surgical treatment, the patient remained free of the urticaria.

Hepatitis C virus (HCV) infection affects about 3% of the world's population and often leads to chronic liver disease. In some industrialized countries, HCV prevalence increases with age, but the optimal management of older patients has not been accurately defined. HCV infection can also lead to lymphoproliferative disorders, the most common being mixed cryoglobulinemia (MC), and also for this condition that frequently affects elderly patients, the optimal therapeutic strategy is still debated. We report the case of a 77-year-old Caucasian woman with HCV-related chronic hepatitis and cutaneous manifestations consisting of urticaria and pruritus related to MC resistant to antihistamines. The patient underwent a treatment with interferon and ribavirin. Such a treatment led to early biochemical and virological response associated with the resolution of cryoglobulinemia and cutaneous symptoms. After the end of treatment, HCV replication relapsed, but cryoglobulinemia and cutaneous symptoms did not recur. In the absence of definite treatment guidelines in this particular context, our experience suggests that the presence of symptoms related to HCV-infection that deeply affect patient quality of life warrants antiviral therapy even beyond the age limits that currently exclude patients from treatment.

Hydroa vacciniforme (HV) and solar urticaria (SU) are uncommon immunologically mediated photodermatoses. HV occurs almost exclusively in children, usually beginning in childhood and remitting spontaneously by adolescence. Association with chronic Epstein-Barr virus infection has been reported in HV, which raises the possibility of lymphoproliferative disorders in these patients. SU is characterized by skin erythema, swelling, and whealing immediately after sun exposure. Although several treatment options are available, the management of both conditions remains a challenge.

Acquired angioedema due to deficiency of C1 esterase inhibitor is also called acquired angioedema and is abbreviated as C1INH-AAE. It is a rare syndrome of recurrent episodes of angioedema, without urticaria, and in some patients, it is associated with B-cell lymphoproliferative disorders. Kidney involvement is rare in this condition. The monoclonal immunoglobulin secreted by a nonmalignant or premalignant B-cell or plasma cell clone, causing renal damage that represents a group of disorders which are termed as monoclonal gammopathy of renal significance (MGRS). In this article, we report a rare case of acquired C1 esterase deficiency angioedema and acute kidney injury with renal biopsy-proven MGRS. We present a 64-year-old Caucasian woman who presented with 2 weeks of recurring urticaria and new onset of acute kidney injury. She was diagnosed with monoclonal gammopathy-associated proliferative glomerulopathy through kidney biopsy, and serological workup came back positive for C1 esterase deficiency, implying acquired angioedema. Acquired angioedema is a rare disease with systemic involvement. Recurrent allergic manifestations and acute kidney injury should prompt MGRS as a differential.
