A. Brief Descriptions：

  1. In healthy individuals ---- asymptomatic or mononucleosis-like infection.

  2. Immunosuppressed patients or neonates ---- devastating systemic infection.

  3. Patients with AIDS ---- almost always accompanied by Pneumocystis carinii.

  4. Recipients of autologous marrow transplants ---- interstitial pneumonitis.

B. Gross Findings：

     略.

C. Micro Findings：

  1. Intracytoplasmic or intranuclear inclusion in tubule.

  2. Basophilic inclusion surrounded by a clear halo -- bull eye appearance.

  3. Interstitial inflammation may present.

D. Others:

  1. Opportunistic infection.

  2. Salivary gland, kidney, liver, lung, pancreas, thyroid, adrenal gland, brain are frequently affected.
