Infectious mononucleosis in the case of two elderly (80 and 57 years old age) patients.

There are reported two cases of infectious mononucleosis in elderly. In the first case (80 years; probably the oldest in the geriatric literature) the infection provoked a very serious illness and the patient deceased three months after dimission, because of diminished resistance. In the second case the mononucleosis induced an autoimmune haemolytic anemia. The patient's daughter and granddaughter must be treated for complications of an infectious mononucleosis too.
