The association of rheumatic syndromes and malignancy is highlighted in this review. The prevalence of malignancy in a series of patients with unclassified rheumatic syndromes is reported. The spectrum of arthropathies associated with malignancy includes bilateral knee effusions, sacroiliitis, and adult-onset Still's disease. There are further reports on the well-recognized association between dermatomyositis and malignancy. The importance of screening for malignancy in patients with classic dermatomyositis as well as dermatomyositis sine myositis is highlighted. The association of mixed cryoglobulinemia with hepatitis C virus infection, hepatocellular carcinoma, and non-Hodgkin's lymphoma is discussed. Finally, the association of miscellaneous rheumatic features such as autoantibodies, vasculitis, carpal tunnel syndrome, and multicentric reticulohistiocytosis with malignancy is described.

With the advent of a minimally invasive laparoscopy technique, the advantages of diagnostic laparoscopy are being rediscovered. We report here on four patients with systemic disease of unknown origin and splenomegaly, in whom minilaparoscopy-guided splenic biopsy yielded a definitive diagnosis. Four patients with unclear systemic disease were studied using diagnostic minilaparoscopy and guided spleen biopsy, after failure of diagnostic work-up. Minilaparoscopic spleen biopsy revealed the diagnosis of a B-cell non-Hodgkin's lymphoma in two cases. In one patient, who had a history of Still's disease, the spleen biopsy showed granulocytic infiltration in the spleen typical of an acute episode of Still's disease. One patient with a known immunodeficiency syndrome (stage C III) showed multiple hypodense lesions in the spleen. Biopsy allowed a diagnosis of mycobacterial infection, with identification of Mycobacterium tuberculosis. No major complications occurred in any of the four cases; post-biopsy bleeding was observed in three of the four, but was easily managed by argon plasma coagulation or application of fibrin glue, or both. We recommend the use of spleen biopsy as a diagnostic tool in splenopathy of unknown origin if previous diagnostic methods have failed to yield a definitive diagnosis.

Brucellosis is a systemic infectious disease caused by Gram-negative bacilli, the genus Brucella, and clinical features are diverse. Therefore, several infectious and non-infectious diseases are considered in its differential diagnosis. In this study, we aimed to determine the positivity rate of Brucella agglutination tests in the culture-positive brucellosis and in diseases mimicking brucellosis clinically.Thirty patients with culture-positive brucellosis, and 280 patients with the diseases mimicking brucellosis clinically (20 with miliary tuberculosis, 33 with malaria, 20 with typhoid fever, 20 with adult-onset Still's disease, 47 with systemic lupus erythematosus, 50 with rheumatoid arthritis, 27 with sarcoidosis, and 63 with active lymphoma) were included in the study. Brucella agglutination tests (Rose-Bengal and Wright) were studied in serum samples of these 310 patients. Both Rose-Bengal and Wright tests (the latter in a titer of 1/160 or higher) were positive in all patients with brucellosis. For the other diseases, the test was slightly positive (1/40) in one patient with malaria and another with non-Hodgkin's lymphoma, and weakly positive (1/20) in a patient with typhoid fever. It remained negative in the remaining. In conclusion, agglutination tests currently used in the diagnosis of brucellosis are very sensitive and specific. Brucellosis can be effectively excluded from the diseases having similar clinical features by the use of agglutination tests.
