ABSTRACT
Multiple myeloma (MM) is a malignant neoplasm of monoclonal plasma cells that accumulate in bone marrow (BM). Malignant pleural effusions (MPE), as part of multiple myeloma clinical presentation, are unusual. Is even more rare as the first sign of presentation, occurring in less than 1% of the cases. The most common associated immunoglobulin with malignant pleural effusions is IgA subtype (80%). This condition carry a poor prognosis. We aim to describe a refractory case of multiple myeloma with extensive disease that presented with extramedullary relapse with malignant pleural effusions , besides discussing the importance of differential diagnosis.
O mieloma múltiplo (MM) é uma neoplasia maligna de células plasmáticas monoclonais que se acumulam na medula óssea (MO). Os derrames pleurais malignos (EPM), como parte da apresentação clínica do mieloma múltiplo, são incomuns. É ainda mais raro como primeiro sinal de apresentação, ocorrendo em menos de 1% dos casos. A imunoglobulina associada mais comum a derrames pleurais malignos é o subtipo IgA (80%). Esta condição carrega um mau prognóstico. Nosso objetivo é descrever um caso refratário de mieloma múltiplo com doença extensa que apresentou recidiva extramedular com derrame pleural maligno, além de discutir a importância do diagnóstico diferencial

As noted under the natural history, the bone of axial skeleton and the ileopelvic lymphnodes specially the obturator groups are the commonest sites of metastasis spread of cancer prostate. Visceral metastasis in the absence of the above is extremely rare. We present a 50-year-male patient of cancer prostate with pleural metastases, pleural effusion and lung collapse on right side. Bone scan was essentially normal. Bilateral orchiectomy was done. Pleural effusion subsided and PSA dropped to 1.4 ng/ml from the initial 120 ng/ml at three months. Patient is on regular follow-up at three monthly intervals and last PSA done at 9 months was 2.1 ng/ml.
