[Hemophagocytic lymphohistiocytosis associated with a lymphohistiocytic pattern anaplastic large cell lymphoma: a case report]. / Syndrome d'activation macrophagique révélant un lymphome anaplasique à grandes cellules de variante lymphohistiocytaire : à propos d'un cas.

We report the case of a 16-year-old girl with an anaplastic large cell lymphoma of lymphohistiocytic pattern revealed by a hemophagocytic syndrome. Histologically, the lymphomatous population was concealed by clusters of histiocytes. Immunohistochemical study allowed the diagnosis. The combination of these two entities is rarely described and may be a source of delay in diagnosis of a life-threatening condition.
