Paclitaxel is an antineoplastic agent derived from the bark of the Pac
ific yew tree that has activity against many tumors including breast a
nd ovarian carcinomas. In the past, its extravasation quality has been
considered to be a local irritant; however, recent reports suggest th
at the agent may be a vesicant. A patient experienced a delayed vesica
nt reaction to a paclitaxel extravasation that resulted in severe necr
osis. No acute symptoms were reported at the time of extravasation fro
m the 24-hour peripheral paclitaxel infusion. However, on day 11 the p
atient complained of severe and progressive pain at the site of extrav
asation. The site was erythematous and had areas of central necrosis r
equiring debridement and closure by a plastic surgeon. Because paclita
xel possesses vesicant characteristics, health care professionals shou
ld be aware of its potential extravasation hazard. Prolonged periphera
l infusions should be avoided or administered with extreme caution.
