Hemophagocytic lymphohistiocytosis (HLH) is a rare syndrome frequently secondary to infectious disease, especially in immuno-compromised patients. We report a HLH secondary to disseminated nocardiosis and Streptomyces spp pulmonary infection. ⋯ Recent diagnosis of HLH without obvious etiology should lead to etiological investigation, including the search for infections with slow-growing bacteria such as Nocardia or Streptomyces spp.
