Pneumocystis pneumonia (PCP) is an opportunistic fungal infection that is usually seen in immunocompromised patients, especially those with HIV, malignancies, organ transplants and on drug therapies like chemotherapy and steroids. PCP has subacute presentation in patients with AIDS which if left untreated gets worse and is a significant cause of morbidity and mortality. Here we present a case of PCP went undiagnosed, partially due to the patient being unaware of his HIV positive status and partially because no organism could be found under the microscope.
