Multiple myeloma presenting initially with pleural effusion and a unique paraspinal tumor in the thorax.
ABSTRACT We herein report an extremely rare case of a patient with IgD-lambda positive multiple myeloma presenting with myelomatous pleural effusion and ascites. A 58-year-old man visited our hospital with dyspnea as his initial symptom. His chest radiograph findings on admission revealed a left pleural effusion, and later, bilateral involvement. Computed tomography (CT) of the chest showed a paraspinal tumor with extension from the upper mediastinum to the abdomen. The cytological examination demonstrated myeloma cells in the pleural effusion and ascites, and histologically, in the pleura, an abdominal subcutaneous tumor and bone was observed. The pleural effusion was an exudate and slightly bloody. The ADA was 70 IU/L. Pleural effusion accompanying myeloma or primary pleural myeloma is very rare and, furthermore, the extremely rare findings of both myeloma cells in the ascites (although the ascites was mainly caused by liver cirrhosis) and a high ADA activity in the pleural fluid were also observed in this case.

ABSTRACT: A patient with mediastinal EP with extension to pleural spaces and subsequent pleural effusion is described. The finding of many plasma cells in pleural fluid led to diagnosis. Similar histologic findings such as multiple myeloma and immunoblastic lymphoma were ruled out by clinical approach and immunochemistry, respectively. This pleural effusion represents the first case described caused by EP.Chest 08/1992; 102(1):296-7. · 5.85 Impact Factor

ABSTRACT: We report the first case of IgA-kappa multiple myeloma presenting as a myelomatous and eosinophilic pleural effusion with increased adenosine deaminase activity. In a review of the literature, 80 percent of myelomatous pleural effusions are due to IgA multiple myeloma.Chest 03/1994; 105(2):622-4. · 5.85 Impact Factor

ABSTRACT: Adenosine deaminase (ADA) can aid in the diagnosis of tuberculous pleural effusions, but false-positive findings from lymphocytic effusions have been reported. The purpose of this study is to assess the ADA levels in nontuberculous lymphocytic pleural effusions (lymphocyte count > 50%) of different aetiologies. Altogether, 410 nontuberculous lymphocytic pleural fluid samples were consecutively selected. These included malignant effusions (n = 221), idiopathic effusions (n = 76), parapneumonic effusions (n = 35), postcoronary artery bypass graft surgery effusions (n = 6), miscellaneous exudative effusions (n = 21) and transudative effusions (n = 51). The ADA level reached the diagnostic cut-off for tuberculosis (40 U x L(-1)) in seven of the 410 cases (1.71%). The negative predictive value of ADA for the diagnosis of pleural tuberculosis was 99% (403 of 407 cases) in the group of lymphocytic pleural effusions. In five of these seven patients ADA1 and ADA2 were measured, and in all these cases (100%) ADA1/ADA(p) correctly classified these lymphocytic effusions as nontuberculous (ratio < 0.42). This prospective study provides additional evidence that adenosine deaminase levels in nontuberculous lymphocytic pleural effusions seldom exceed the cut-off set for tuberculous effusions. The pleural fluid adenosine deaminase levels were significantly higher in different types of exudative effusions than in transudates. An adenosine deaminase level < 40 IU x L(-1) virtually excluded a diagnosis of tuberculosis in lymphocytic pleural effusions. Adenosine deaminase1/adenosine deaminase(p) correctly classified all nontuberculous lymphocytic pleural effusions with high adenosine deaminase levels.European Respiratory Journal 02/2003; 21(2):220-4. · 6.36 Impact Factor
