RÉSUMÉ
Abstract Multiple myeloma (MM) is a hematological malignancy characterized by unregulated and clonal proliferation of plasma cells in the bone marrow; these cells produce and secrete an anomalous monoclonal immunoglobulin, or a fragment of this, called M protein. The clinical manifestations of MM result from the proliferation of these plasmocytes, the excessive production of monoclonal immunoglobulin and the suppression of normal humoral immunity, leading to hypercalcemia, bone destruction, renal failure, suppression of hematopoiesis and humoral immunity, increasing the risk for the development of infections. The increase in life expectancy of the world population led to a concomitant increase in the prevalence of MM, a pathology that usually affects the elderly population. The aim of this review is to update the reader on epidemiology, diagnostic criteria, differential diagnosis with other monoclonal gam-mopathies, systemic treatment and prognosis of MM.
Resumo O mieloma múltiplo (MM) constitui neoplasia maligna de origem hematológica caracterizada pela proliferação desregulada e clonal de plasmócitos na medula óssea; estas células produzem e secretam imunoglobulina monoclonal anômala, ou um fragmento desta, denominado proteína M. As manifestações clínicas do MM decorrem da proliferação destes plasmócitos, da produção excessiva de imunoglobulina monoclonal e da supressão da imunidade humoral normal, levando à hipercalcemia, destruição óssea, insuficiência renal, supressão da hematopoiese e da imunidade humoral,aumentandooriscoparaodesenvolvimento de infecções. O aumento na expectativa de vida da população mundial levou a concomitante incremento na prevalência do MM, patologia que habitualmente acomete a população idosa. O objetivo desta revisão é atualizar o leitor sobre a epidemiologia, critérios diagnósticos, diagnóstico diferencial com outras gamopatias monoclonais, tratamento sistêmico e prognóstico do MM.

Strongyloides stercoralis (S.S.) is a human intestinal parasite, which may lead to complicated strongyloidiasis. We report a case of disseminated strongyloidiasis following the treatment of myeloma. The patient developed skin lesions, respiratory distress, aseptic meningitis and bacterial and fungal sepsis. The diagnosis of strongyloidiasis was established through endotracheal tube secretions. Despite the treatment with Ivermectin and Albendazole, the outcome was fatal. The value of screening for strongyloidiasis is unclear but may be of benefit in patients with hematological malignancies from high endemic areas.

En el presente artículo se realiza una revisión bibliográfica de un neoplasia fundamentalmente del hueso llamada mieloma, en donde se destacan aspectos etiológicos, clínicos, radiográficos e histopatológicos de la lesión; al mismo tiempo se presentan 5 casos de los cuales 3 se corresponden con el diagnóstico de la enfermedad y dos de éstos se presentan como diagnóstico diferencial, ya que se mostraron con características similares.
