[Macrophagic activation syndrome revealing Hodgkin lymphoma: an individual case].

Macrophagic activation syndrome (SAM) or Hemophagocytic lymphohistiocytosis is a clinical-biological entity of non-specific proliferation and activation of macrophages of the reticulohistiocytic system, with phagocytosis of the figurative elements of blood. It is a rare pathology combining non-specific clinical and biological signs and images of hemophagocytosis. It can be primary or acquired secondary to an infection, an autoimmune or neoplastic disease. While T or NK lymphomas are the classic causes of reactive SAM and its association with Hodgkin lymphoma is exceptional. This is a diagnostic and therapeutic emergency given the risk of development towards a fatal multivisceral failure due to an absence of appropriate support. This is a report of a case of SAM revealing a case of Hodgkin lymphoma in a 35-year-old patient.
