Introduction:
Pneumocystis is a common opportunistic infection in patients with severe
T-cell immunodeficiency. Its occurrence in patients with solid tumors is
relatively rare, unless additional significant predisposing factors are
present.
We present the case of a patient who developed a Pneumocystis
jirovecii pneumonia after the 9th course of Paclitaxel, administered as
part of adjuvant chemotherapy for breast cancer.
