[Pleural effusion as the only manifestation of cryptococcosis in an AIDS patient].

Cryptococcosis is often seen in immunodeficient patients, including those with AIDS. It usually affects mainly the respiratory tract and central nervous system. We present a rare case of pleural involvement with no sign of disease at other sites. A review of the literature yields only three other similar cases. We discuss the diverse clinical manifestations of cryptococcosis, particularly those found in the respiratory tract.
