RESUMO

Hemophagocytic syndrome (HS) is a severe hyper inflammatory condition whose cardinal symptoms are prolonged fever, cytopenia, hepatosplenomegaly, and hemophagocytosis by activated, morphologically benign macrophages. The clinical course resembles sepsis, sharing similar physiopathological features. We report four patients with the syndrome. A 61-year-old female presenting with fever and pleuritic pain. During the course of the disease, a pancytopenia was detected and a bone marrow aspiration was suggestive of HS. The patient was treated with cyclosporine and steroids with a good response. A 61-year-old male with fever and pancytopenia and a bone marrow aspirate suggestive of HS. The patient did not respond to treatment and died. A 23-year-old male with fever, pancytopenia and positive Hanta virus antibodies. A bone marrow aspirate was suggestive of HS. The patient recovered without any treatment. A 72-year-old male admitted with the diagnosis of pneumonia, that developed a progressive pancytopenia and bone marrow aspirate was suggestive of HS. A bronchoalveolar lavage showed the presence of Acinetobacter baumanii. Despite treatment with methylprednisolone and gammaglobulin, the patient died. Awareness of the clinical symptoms and of the diagnostic criteria of HS is important to start life-saving therapy in time.

RESUMO

La amiloidosis sistémica primaria y el mieloma múltiple con amiloidosis primaria se han presentado con características clínicas e histopatológicas que simulan una arteritis de células gigantes. Hasta el momento la asociación se basaba en el rol antigénico del depósito de amiloide sobre las arterias, desencadenando la respuesta inmune que finaliza con una arteritis. Presentamos el primer caso en la literatura de un paciente con mieloma múltiple y arteritis de células gigantes sin amiloidosis sistémica, sugiriendo una relación patogénica entre estas dos entidades. En el caso de nuestro paciente se descartó la presencia de amiloide en la pared arterial, por lo que proponemos que el estímulo para el desarrollo de la arteritis podría ser una excesiva producción de interleuquina 6 fabricada por las células mielomatosas


Primary systemic amyloidosis with clinical and histopathologic features of giant cell arteritis has already been described. The association of multiple myeloma (with primary amyloidosis) and giant cell arteritis is also known. We present the first case in the literature of a patient with multiple myeloma and giant cell arteritis without systemic amyloidosis, suggesting a pathogenic relationship between the two diseases
