[Pneumocystis pneumonia in two breast cancer patients treated with docetaxel: an unusual adverse event of chemotherapy]. / Deux observations de pneumocystose chez des patientes traitées par docétaxel pour un cancer du sein : une complication inhabituelle de la chimiothérapie.

We report two cases of pneumocystis pneumonia in patients receiving chemotherapy for breast cancer. These case series emphasize the frailty of the patients as the causative role for occurrence of this uncommon complication of chemotherapy in breast cancer. We remind the importance of screening for unusual adverse events in frail patients receiving chemotherapy.
