The clinical spectrum of hypersensitivity reactions reported with pacl
itaxel has not included the occurrence of pulmonary infiltrates. This
report describes three patients who developed transient pulmonary infi
ltrates after receiving paclitaxel. These infiltrates were noted 2 day
s to 2 weeks after administration of paclitaxel. The infiltrates resol
ved spontaneously in all the patients but one of them did receive ster
oid therapy. This syndrome of transient pulmonary infiltrates did not
reoccur in the two patients who were rechallenged with paclitaxel. Phy
sicians should be made aware of this unique occurrence during the cour
se of treatment with paclitaxel.
