Lymphopenia is a reduction in the numbers of lymphocytes in the blood.  This phenomenon is most commonly associated with stress (as part of the '''stress leucogram''') or with viral infection.  Causes include:
 
Lymphopenia is a reduction in the numbers of lymphocytes in the blood.  This phenomenon is most commonly associated with stress (as part of the '''stress leucogram''') or with viral infection.  Causes include:
*[[Stress leucogram]], characterised by '''[[Neutrophilia|neutrophilia]]''', '''[[Monocytosis|monocytosis]]''', '''[[Eosinopenia|eosinopenia]]''' and '''[[Lymphopenia|lymphopenia]]'''.  A similar pattern may occur with hyperadrenocorticism (Cushing’s disease) or exogenous corticosteroid therapy as these hormones selectively suppress lymphocytic activity and the inflammatory response in general.

*Bone marrow suppression caused by '''chemotherapy''' or '''radiotherapy'''.  Since neutrophils have a much shorter circulating half life, they are the first cell line to fall with any insult to the bone marrow but lymphopenia may occur as part of a more severe pancytopenia.
