Pneumocystis Pneumonia in a Non-AIDS Patient

We present a unique case of <i>Pneumocystis jirovecii</i> pneumonia (PCP) in a patient with HIV. Both treated and untreated HIV patients are susceptible to opportunistic pathogens. Depending on the patient's underlying cluster of differentiation 4 T-cell (CD4 T-cell) count, HIV is associated with a wide range of infections. Historically, PCP has been observed in HIV patients with AIDS or in those receiving immunosuppressive therapy. However, it should remain a differential diagnosis in patients who present with comorbidities and symptoms of acute lung disease.
